  • 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

    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
