DP Technology Now Shipping ESPRIT 2013

Written by

Computer-aided manufacturing (CAM) industry leader DP Technology Corp. is now shipping ESPRIT® 2013, the latest version of its flagship software, designed to program today’s multi-spindle, multi-turret mill-turn and Swiss-turn machine tools.

ESPRIT 2013 includes new productivity-enhancing technology for all CNC programmers and for all machining disciplines. This latest version focuses on providing new and enhanced machining technology that ensures smarter, more efficient toolpath and new strategies for greater overall productivity.

Featuring functionality that emphasizes higher cutting speeds, longer tool life and suitability to increasingly complex geometry, ESPRIT 2013 is comprehensive in its ability to handle today’s most advanced machine tools and demanding machining applications.

New ProfitMilling Pocketing

Experience better CAM programming with ProfitMilling, a smart and efficient toolpath that puts greater profit in your pocket. New to ESPRIT 2013, the patent-pending ProfitMilling strategy for 2-, 3- and 5-axis roughing cycles allows customers to remove more material in a shorter period of time. Using highly advanced technology, the ProfitMilling strategy optimizes engagement angle, chip load, material removal rate (MRR), lateral cutter force and machine acceleration to achieve optimal results.

This innovative machining cycle represents the “best of both worlds” by utilizing trochoidal tool motion and a traditional offset of the toolpath, allowing usage of the full tool flute length.

“Our tests have shown that ProfitMilling typically reduces cycle time by 70 percent, minimizes programming time, reduces energy consumption, and increases tool life by an average of 500 percent,” said ESPRIT Product Manager Kenyon Whetsell. “We’ve seen the most dramatic benefits in using the ProfitMilling strategies with light to medium-duty machine tools.”

Trochoidal tool motion pattern has been improved in ESPRIT 2013 to take you even faster through your cuts.

Improvements include an optimized trochoidal strategy to reduce cycle time and additional tool lifts during transitional moves to reduce tool drag.

New Improvements to Lathe Grooving

ESPRIT 2013 offers new options for cutting grooves faster and more efficiently by taking advantage of the latest technology in grooving inserts. Among these upgrades is a new plunge setting added to the plunge turning (zigzag) cycle. Using a pre-plunge along walls reduces the tool load against walls and cuts wide grooves faster.

Also added is a lateral feed-rate setting that provides customers with more control and an option to perform extra-plunge along a profile to deliver fewer scallops for the finish pass. Also new in ESPRIT 2013 are two new strategies for the “Diagonal Zigzag” groove type: “Thin-to-Thick Chip” for a progressive engagement of the tool and “Thick-to-Thin Chip” that is particularly suited to ceramic inserts. It generates rapid metal removal without vibration, as well as improved finish and prolonged tool life.

Engraving

ESPRIT 2013 offers a completely new editable and customizable engraving machining cycle that allows customers to use “True Type” fonts, single-stroke fonts or features of the part geometry. In addition to more conventional contouring and pocketing machining strategies, the ESPRIT 2013 engraving cycle introduces an available V- carving strategy. V-carving is dedicated to the usage of engraving tools with tapered ends. This strategy, specific for use with tapered engraving tools, offers benefits that include more accurate and aesthetic designs, the ability to machine sharp corners, and reduced cycle time.

Advancements to 3- and 5-axis ESPRIT FreeForm Cycles

A new 5-Axis Roughing Cycle has been designed to quickly and easily rough a 5-axis part using the same familiar technology used to rough a 3-axis part, including the new ProfitMilling pattern. The 5-Axis roughing cycle automatically adjusts the orientation of any tool shape (end mill, ball mill, bull-nose mill) to keep the tool perpendicular to the underlying surface, thereby eliminating undercuts.

Also new to ESPRIT 2013 is a 5-Axis Port Machining Cycle dedicated to machining cylindrical apertures and devised to cut as deeply as possible into a port while containing tool swings. This cycle is aided by an automatic recalculation of tool points along a spine curve.

ESPRIT 2013 features improvements for all 5-axis cycles, including the new, patent-pending 5-axis channel-roughing cycle. By directly selecting channel walls without creating complicated features, machining channels between thin blades is faster and easier than ever before; simply select the walls on either side of the channel, set the incremental depth and go. Another important enhancement is the ability to generate multi-level cuts by input of an incremental depth of cut.

Improvements to the 5-Axis Blade Machining Cycle include the ability to optimally machine a single blade from one end to the other. A new hub-blending option eliminates unwanted interruptions in the cut that occur when the tool reaches the end of the blade and comes into contact with the hub surface.

Additionally, the Impeller Machining Cycle now includes built-in remachining, which allows for the complete machining of an impeller without concern for tool dimensions. The impeller cycle allows customers to machine as far as possible using the current tool before automatically stopping at the first unreachable level. The system retains the maximum depth increment machined, which is then used to start the next roughing remachining. This flexible method allows multiple remachinings with decreasing tool sizes. The impeller cycle offers additional control over the tool orientation to avoid undesired table swing.

Built-in Collision Avoidance in Multi-Axis Milling

In ESPRIT 2013, new collision-detection strategies have been added to all 3-axis and 5-axis milling operations, which detect collisions while toolpath is being calculated instead of during the simulation process. ESPRIT can be instructed to recommend the minimal tool length to avoid collision, or to automatically trim away the colliding toolpath and reconnect with appropriate links.

New Geometry for Multi-Axis Machining

The machining of engine ports and turbine blades requires precise control of tool motion, and ESPRIT 2013 makes the task easier than ever before with new curves and surfaces to guide the tool.

A major enhancement unique to ESPRIT 2013 is a new “Mid Surface” function added to the Knitted Surfaces toolbar.

The new “Mid Surface” function is perfect for blade machining, where it serves two purposes: allowing for the calculation of toolpath from a single source instead of multiple faces on the model, and controlling the orientation of the tool axis throughout the cut, rather than on individual surfaces of the blade.

The new “Spine Curve” option creates a curve along the centers of radial surfaces and is ideal for port machining, as it allows programmers to guide the tool as far as possible into the opening.

The “Curve From Surface” command has been enhanced in ESPRIT 2013 with a new option to create either a parametric curve or a spine curve.

New Improvements to Wrap Machining

“Wrap Pocketing” and “Wrap Contouring,” enhanced for ESPRIT 2013, now support the machining of non-cylindrical parts. In addition to wrapping a feature on a working diameter, a 3D feature chain may also be selected as an input, no longer necessitating “unwrapping” the feature. A distinct advantage over the legacy cycles, current wrap operations also offer the user the ability to apply a Y-axis offset in order to obtain the desired wall geometry.

Computer-aided manufacturing (CAM) industry leader DP Technology Corp. is now shipping ESPRIT® 2012, the latest version of its flagship software designed to program today’s multi-spindle, multi-turret mill-turn and Swiss-turn machine tools.

Performance-enhancing upgrades built into this new version of ESPRIT provide existing ESPRIT customers with additional tools to increase productivity. Included in ESPRIT 2012 are a significant number of innovative programming technologies for all machining disciplines — including 2-5 axis milling, 2-22 axis turning, 2-5 axis wire EDM, multi-tasking mill-turn, and high-speed 3- and 5-axis machining.

ESPRIT’s high-performance capabilities include machining any part geometry — solid, surface, or wireframe — universal post processing to format G-code for virtually any machine tool, and solid simulation and verification with dry runs rendered in dynamic solids for optimal part quality and consistency.

ESPRIT 2012 is available now and runs on the Microsoft® Windows® 7™ and Microsoft® Vista™ operating systems.

Advancements to 3-and-5-axis ESPRIT FreeForm Cycles
Numerous enhancements and additions have been made to 3-and-5-axis FreeForm cycles in ESPRIT 2012.

Among them is a new 5-axis trochoidal channel-roughing cycle that utilizes a circular toolpath to constantly adapt to the shape of a cavity bounded by two walls, which allows the machining of deep cavities with thin walls.

Also new to ESPRIT 2012 is a 5-axis blade cycle that creates finishing toolpath on a single blade. This new cycle is designed specifically for the challenges of optimizing the toolpath on models with convex faces on one side and concave faces on the other.

Among all-new 5-axis impeller-cycle upgrades unique to ESPRIT 2012 are a wider array of settings that include a “single pass” roughing strategy that creates multiple cuts down the center between the blades before roughing starts.

A new “roll around edges” setting enables users to roll the tool around blade edges to guarantee an overlap of the toolpath.

A new “spiral” option creates spiral toolpath that expands outward from the mid-line between the blades for smoother toolpath that keeps the tool on the part. Likewise, multi-blade optimization with new settings for “number of blades” and “cut all blades” offers options for machining priorities to cut blades by either region or by level to prevent deflection and vibration when the blades are thin.

All 3-axis FreeForm cycles have been improved with enhanced distribution of points in the toolpath and autotilt options to transform 3-axis toolpath into 5-axis. Autotilt is ideal when short rigid cutting tools are used in deep cavities.

Improvements have also been made to ESPRIT’s existing knitted surface option, which creates a single surface from any number of faces on a solid model. New to ESPRIT 2012 is the ability to cover openings in more than one face with knitted surfaces.

Expanded Machining Cycles in all Disciplines
ESPRIT 2012 offers upgrades in all machining disciplines, with enhancements to turning, milling, mill-turn and wire EDM cycles.

For turning, the “park” cycle has been redesigned in ESPRIT 2012 to allow a machine tool’s head or turret to be parked. Increased versatility is achieved with the enhancement of allowing parking on each axis, which can be individually controlled using one of the four modes available — not parking the axis; moving the axis to home, as it would be set for a tool change; the tool moves to the input position in the operation coordinate system, or the axis moves to the input position in the machine-coordinate system.

For milling, ESPRIT 2012 offers an enhanced method of treating features used for contouring operations. Rather than allowing the tool to "roll" over the edge when at or near the starting depth, the feature edge can be extended to maintain the desired shape.

For wire EDM, new feature extension settings make it possible to extend the extremities of the feature so the wire path can start or end outside of the material when contouring or with EDM turning operations. This allows the wire path to be extended without actually modifying the feature. A new “dwell time” setting that inserts a dwell at the end of the rough cut to enlarge the exit point, ensuring that the wire for the skim cut can be re-threaded, has been added to all EDM contouring cycles.

Computer-aided-manufacturing (CAM) industry leader DP Technology, creator of ESPRIT®, will exhibit ESPRIT 2011, the latest version of its innovative software, at Precision Machining Technology Show, or PMTS, 2011, scheduled for April 19-21 in Columbus, Ohio.

PMTS, a biennial international forum for manufacturers, suppliers and users of products dedicated to the production of precision-machined and turned parts, will take place this year at the Greater Columbus Convention Center.

Visitors to PMTS 2011 are encouraged to visit ESPRIT at booth No. 1010, where knowledgeable DP representatives will be available to discuss vital upgrades and perform demonstrations of how those upgrades can be put to work for you.

SolidTurn® drilling has been enhanced in ESPRIT 2011 with the addition of “Full Clearance” as an option for “Return Plane.” The advantage of adding the “Full Clearance” option to the drilling cycle is that the user can set and view the distance on the technology page.

To better support Swiss-style turning, a new lead-out option, called “Edge Break,” has been added to ESPRIT 2011. Swiss-style lathes utilize a guide bushing to support the bar stock for better rigidity. Occasionally, it is necessary to retract the turned stock back into the guide bushing. If there is a burr on the outer diameter (OD) of the stock, the guide bushing could jam or be damaged when the stock retracts. The new “Edge Break” option for the lead-out move will create a chamfer move to break the edge of the stock at the OD.

Computer-aided-manufacturing (CAM) industry leader DP Technology, creator of ESPRIT®, will exhibit ESPRIT 2011, the latest version of its innovative software, at Eurostampi 2011, slated for March 24-26 in Parma, Italy.

Considered an important platform for both users and exhibitors, Meccanica Specializzata, or Specialized Mechanics (MecSpe) Eurostampi 2011, is an international exhibition of mold, press and injection-mold machines. Exhibitors from around the globe attend the event to present the latest mold-industry specific software, equipment and processing techniques.

Visitors to Eurostampi are encouraged to visit the ESPRIT exhibit, at which knowledgeable representatives of DP Technology will be available to discuss vital upgrades and perform demonstrations of how those upgrades can be put to work for you.

Among significant enhancements included in ESPRIT 2011 are upgrades to 3-and-5-axis ESPRIT mold cycles.

Among these upgrades is the new tangent pass extension toolpath option, which allows users to apply a tangent extension at the two extremities of open passes. This new option has been added to parallel planes, Z-level and between-curves finishing, as well as to 5-axis composite milling.

For all 3-and-5-axis SolidMill® Mold cycles, “Retract Optimization” has been updated with a new option called “Within Operation” that optimizes retracts within the operation. The tool starts and ends at the full clearance height.

Among several enhancements made to all 5-axis mold cycles is a new option for controlling the orientation of the tool axis within the composite cycle. This new “Normal to Model” orientation strategy keeps the tool axis perpendicular to model surfaces regardless of the selected drive surface.

This new strategy is advantageous when a knitted surface is selected as a drive surface for a projected toolpath (‘Machining Pattern’ set to ‘Project Parametric Pattern’ or ‘Project Spiral’).

Computer-aided manufacturing (CAM) industry leader DP Technology Corp. is pleased to announce the release of ESPRIT® 2011, the latest version of its ESPRIT flagship product.

Upgrades within the latest version of ESPRIT provide new productivity-increasing tools that focus on both the immediate needs of ESPRIT’s current users and the long- term direction of the manufacturing community.

Included in ESPRIT 2011 are a significant number of innovative programming technologies for all machining disciplines — including milling, turning, wire EDM, multitasking mill-turn, and high-speed 3- and 5-axis — in addition to notable system-wide enhancements and new analysis tools. ESPRIT 2011 is designed to run on both the Microsoft® Windows® 7™ and Microsoft® Vista™ operating systems.

New Analysis Tools in ESPRIT 2011

New to ESPRIT 2011 are a series of analysis tools — the zebra, porcupine, heat map and toolpath analysis commands — that provide graphic displays for the inspection of solid models and ease in programming.

The ‘Zebra’ command simulates the reflection of long strips of light on a shiny surface, making it easy to spot wrinkles or defects in a surface. The striped display also makes it easier to verify that two adjacent faces are in contact, are tangent, or have continuous curvature. If stripes smoothly connect from one face to another, elements are tangent. This tool can save substantial time and money by enabling the detection of part model imperfection before parts are machined.

The 'Porcupine' command displays normal vectors on faces and surfaces to aid in the visualization of changes in part curvature, which assists with the selection of ideal machining strategies.

The ‘Heat Map’ command displays surfaces rendered in different colors according to the local radius of curvature. This allows users to review minimum and maximum curvatures for the selection of the most appropriate cutting tools.

The 'toolpath analysis' command traces the position of the tool along a selected toolpath to aid in evaluating toolpath smoothness and to examine the quality of point distribution.

Improvements to ESPRIT Milling Cycles
Pocketing and trochoidal pocketing have been enhanced in ESPRIT 2011 to recognize feature properties for top blends, bottom blends and walls with different tapers. ESPRIT 2011 now finds the contact point with the feature according to the blend information.

If a pocket contains multiple sub-pockets with different tapers and multiple islands with different tapers, users can now machine those pockets with one operation.

Additionally, open-pocket toolpath now supports wrap pocketing, open islands and the “extra moves” parameter.
Chamfer milling is fast and easy in ESPRIT 2011, and blend properties have been added to chain and profile features.

This means that, when “Top Blend Type” or “Bottom Blend Type” is set to “Chamfer,” additional properties can be defined for the chamfer angle and depth. When the chamfer property is properly set on the feature, the toolpath will automatically adapt to find the touch point between the tool and the chamfer profile.

Upgrades to 3-and-5-axis ESPRIT Mold Cycles
Numerous enhancements have also been made to 3-and-5-axis cycles.

Among these upgrades is the new tangent pass extension toolpath option, which allows users to apply a tangent extension at the two extremities of open passes. This new option has been added to parallel planes, Z-level and between-curves finishing, as well as to 5-axis composite milling.

For all 3-and-5-axis SolidMill® Mold cycles, “Retract Optimization” has been updated with a new option called “Within Operation” that optimizes retracts within the operation. The tool starts and ends at the full clearance height.

Among several enhancements made to all 5-axis mold cycles is a new option for controlling the orientation of the tool axis within the composite cycle. This new “Normal to Model” orientation strategy keeps the tool axis perpendicular to model surfaces regardless of the selected drive surface. This new strategy is advantageous when a knitted surface is selected as a drive surface for a projected toolpath (‘Machining Pattern’ set to ‘Project Parametric Pattern’ or ‘Project Spiral’).

Upgrades to ESPRIT Turning Cycles
SolidTurn® drilling has been enhanced in ESPRIT 2011 with the addition of “Full Clearance” as an option for “Return Plane.” The advantage of adding the “Full Clearance” option to the drilling cycle is that the user can set and view the distance on the technology page.

To better support Swiss-style turning, a new lead-out option, called “Edge Break,” has been added to ESPRIT 2011. Swiss-style lathes utilize a guide bushing to support the bar stock for better rigidity. Occasionally, it is necessary to retract the turned stock back into the guide bushing. If there is a burr on the outer diameter (OD) of the stock, the guide bushing could jam or be damaged when the stock retracts. The new “Edge Break” option for the lead-out move will create a chamfer move to break the edge of the stock at the OD.

Upgrades to ESPRIT Wire EDM Cycles
In many 4-axis wire EDM machining situations, users need the ability to thread the wire at an angle to match the tilt of a cavity or when a wire cannot be threaded vertically.

That need has been met in ESPRIT 2011, in which EDM 4-axis features can now be modified to add a tilted thread angle for 4-axis contouring and pocketing operations.

Also included is improved automatic recognition of dies, holes and punches from solid models. Once the part type is selected, ESPRIT does the rest automatically.

System-Wide Upgrades in ESPRIT 2011
System-wide upgrades within ESPRIT 2011 increase ease-of-use and productivity, and include the enhanced management of post-processor files and ESPRIT updates.

Post Processors files are now managed in the machine set-up, which allows users to associate one or more post processers with a specific machine. This upgrade translates to faster access to NC code and better management of NC code programs, support for multiple post processors, and machine “memory” regarding which post processor should be used.

As ESPRIT updates are now managed directly inside ESPRIT, users can now link to the DP Technology Web site to check for, download and install ESPRIT updates.

Frivolous fanfare was not on the set list in early December, when ESPRIT took the main stage for DP Technology’s premier West Coast skill builder event in Costa Mesa, Calif.

Created to help ESPRIT’s users take advantage of time-saving tips and tricks, the day of no-cost training was supplemented with presentations from users and partners with unique insights on the software.

“The user seminar was the best opportunity to discover some new ways to utilize ESPRIT and uncover a few mistakes I’ve been making when approaching part features and processes,” said Bob Lewis of Metalore, an El Segundo, Calif.-based company that specializes in the manufacturing of precision parts for the motor sports, military hardware and medical sectors.

In addition to attending the event, Lewis shared his stories of success with peers in attendance. “It was a great opportunity to discuss the parts and processes of Metalore with participants having different parts but similar issues when processing parts,” he said.

James Kim, an applications engineer for Agie Charmilles, LLC, was invited to speak about the latest wire EDM developments, particularly rotary wire EDM applications.

“This allowed ESPRIT end users from diverse machining backgrounds to see sample application examples and programming approaches, and to see and feel rotary EDM sample parts up close, in their hands,” Kim said. “I met customers face-to-face after my presentation and was pleasantly surprised to see great interest and excitement in their eyes.”

With thorough coverage provided by experienced ESPRIT instructor and Application Engineer Paul Walczyk, the skill-building event was designed to do just that — build skills. Created to get into the nuts and bolts of the software, the day of learning in a casual atmosphere was meant to provide ESPRIT customers with tools they can really use.

"There is something to be said about being interactive," Walczyk said. "It's a great chance to ask questions and have them answered on the spot."

Walczyk encourages future attendees to bring both questions and feedback.

"This gives us an opportunity to collect information about what end-users are looking for in the future," he said. "They get to see what's new, but they also give us an idea of what's needed and this information is given to R&D (research and development) for consideration."

“The goals of the skill builder event were to deliver training on a variety of hidden gems in ESPRIT, as well as to share powerful success stories from our users,” said DP Marketing Events Manager Shelby Paul.

The event was also an opportunity for users to learn about ESPRIT’s current development plan, recent acquisitions and partnerships, and the ESPRIT of today and the near future.

“We wanted attendees to come away with valuable new tricks and to be inspired to take on new challenges with ESPRIT,” Paul said. “The Costa Mesa event was a complete success and we look forward to bringing it to cities across the U.S. in the next several months.”
