DP Technology Corp. is a software company founded in 1982 that has 120 employees and a worldwide presence across over 50 countries. They produce ESPRIT CAM software that provides full-spectrum 5-axis machining capabilities for milling, turning, and mill-turn applications. ESPRIT supports advanced features for machining complex parts like impellers and blisks with capabilities like impeller-specific cycles, rolling edge support, trochoidal channel roughing, pinch milling, and more. Customers praise ESPRIT for its flexibility and ability to optimize multi-function machining.

3. 28 years Experience in CNC and CAM software

4. Managed by Founders

6. ESPRIT Customers

7. ESPRIT 2011 Full-spectrum CAM for Power, Utility, Oil, and Gas Engineering 2 to 5-axis milling Including over 30 5-axis simultaneous cycles Dedicated impeller 5-axis machining cycle Multiple axis turning Unlimited number of turrets and spindles Full C-axis and Y-axis mill-turn support Multi-tasking/Mill-turn machining B-axis mill-turn

8. ESPRIT Impeller Cycle Support for impellers with or without splitter blades Roughing and finishing Parametric and contour offset tool motion patterns Taper tools support Collision free tool path for impellers and blisks

9. New Developments in Impeller/Blisk Machining Rolling edge support improves the tool path quality at the trailing and leading edges of the blades Available for both roughing and finishing Support for both impellers and blisks

10. New Developments in Impeller/Blisk Machining Trochoidal Channel Roughing tool moves along a circular path that constantly adapts to the channel shape allows machining of deep cavities with thin walls (blisks) suitable for difficult-to-machine materials, like Titanium can replace several phases of conventional machining

11. Blade Machining Blade roughing accomplished by 3+2 (cut in 3-axes, position in 2-axes) machining Any possible combination of axes can be defined Finishing accomplished using 5-axis cycle Possible tool motion patters 4 possible tool orientations In-line and cross angle settting

12. New Developments in Blade Machining “Foil Surface” tool orientation A robust algorithm for forward/cross angle calculation Eliminates large accelerations in the tool path Allows programmers to use “less than perfect” CAD data without the need for healing the solid Works especially around the themost critical zones (leading and trailing edges of the blade) “bad CAD data” red foil surface

13. New Developments in Blade Machining Acceleration Control The tool axis rotation around the edges is anticipated/delayed in order to keep acceleration of the rotary axis constant Without this control, the rotation of the tool around the blade edges causes a sharp angle in the tool-end trajectory (discontinuities) and a bad surface finish The result of acceleration control is smooth tool movement with no jerking, producing a high-quality part surface

14. New Developments in Blade Machining Pinch Milling Lower turret leads the upper turret, cuts semi-finish Upper turret trails, cuts the finishing in 5-axes

15. Pinch Milling Advantages Semi-finish program cycle time is completely eliminated: cycle time reduction 35% Blade is stabilized during finishing and semi-finishing operations by the lower turret Utilizes main and sub spindles to drive rotary axis – no twisting of airfoil Part can be placed into “tension” using the sub spindle – better surface finish

16. ESPRIT for Turning Support for an unlimited number of turrets Indexing turrets “Swiss-style” gang tooling Automatic tool changing “multi-tasking” style turrets Support for an unlimited number of spindles Tailstock and steady rest support

17. Turning – Shafts Simulation Eliminate dry runs at machine Entire machining environment Advanced tool path control Control of lead in – lead out Many cycles – special grooving Increase tool life Accuracy of machining Tool nose compensation control

18. Turning – Large Part; Vertical or Horizontal Simulation Collision checking Specialized attachments Special machining cycles

19. Turning – Large Part

20. Generator Shaft - Grooving Development of special cycles using API Accurate simulation Special tools

21. Automation in ESPRIT API – Application Programming Interface Allows users to customize ESPRIT Microsoft VBA (Visual Basic for Applications) is integrated into ESPRIT Can be accessed from any programming environment that supports Microsoft’s Component Object Model (COM) KBM – Knowledge Base Machining Teach ESPRIT to program your parts Control tooling, feeds and speeds, and operations FX – Feature Exchange Import manufacturing data directly from CAD file

22. What are our customers saying about us? ESPRIT by DP Technology provided all of the capabilities we were looking for.” — Marc Pollok, MSI Products “The real strength of ESPRIT lies in the tools that it provides to optimize the operation of a multifunction machine ...” — Walter Lentz, Halliburton “Only a few companies had software that could handle the mill-turn machines ... We selected ESPRIT primarily because of the flexibility of its postprocessor.” — Tom Lawler, Fairfield Manufacturing
