Multi-Axis Turning | Hurco IMTS 2012

  1. 1. Multi-Axis Turning Getting back to basics…
  2. 2. Machine Configurations TMM 3-axis (X, Z, C) TMXMY 4-axis or TMXMYS 6-axis (X, Y, Z, C) or (X, Y, Z, W, C, C3)
  3. 3. TMX 2-axis ( X, Z, W )Programmable Tailstock Z-Axis X-Axis Programmable Tailstock
  4. 4. Programmable C-Axis TMM & MY/MYS  Fully programmable C-Axis rotary axis for contouring operations  Can be clamped in place for more rigidity when necessary
  5. 5. MY / MYS Machine Y-Axis Configuration 2-Axis Wedge Design • X-Axis • Used to compensate for clearance of the moving Y-axis • Y-Axis • Programmed as perpendicular plane to the X-axis. C3-Axis (sub-spindle)
  6. 6. Visualize Movement Click for Video Y-Axis Perpendicular to X-axis
  7. 7. C-Axis Milling Y-Axis Milling(always points to center) (allowed to move laterally)
  8. 8. C-Axis Drilling Y-Axis Drilling(always points to center) (allowed to move laterally)
  9. 9. Let’s Talk PartsExamples…
  10. 10. TMM Parts All features on centerline C-axis & X-axis correlation for axial milling of flats Click for Video
  11. 11. TMM Parts C-axis & X-axis correlation for axial milling off center circles Click for Video
  12. 12. MY/MYS Parts Features can be off-centerline of the workpiece Flats can be milled using the Y-axis Click for Video
  13. 13. Real-World ExampleShow me the money…
  14. 14. 2 - Axis LatheOperation Setup Time Cycle Time Description Face, Turn OD Profile, Groove 1 1 hr 5:35 OD, Thread, Drill, Bore ID, Cutoff Face OAL, Turn OD Profile, Bore 2 30 min 1:27 ID Total 1.5 hours 7:02 3-Axis MillOperation Setup Time Cycle Time Description 1 30 min 1:03 Mill Hex 2 30 min 1:17 Mill Slot Total 1 hour 2:20 Grand 2.5 Hours 9:22 Total
  15. 15. Multi-Axis Lathe Operation Setup Time Cycle Time Description Face, Turn OD Profile, Groove 1 30 min 6:57 OD, Thread, Drill, Bore ID, Mill Slot, Cutoff Face OAL, Turn OD Profile, Bore 2 30 min 1:38 ID, Mill Hex Total 1 hour 8:35 Grand 1 Hour 8:35 Total Total Time Savings 1.5 Hours :47Saving Time …while the mill runs other work
  16. 16. Multiple OperationsConserving Turret Stations
  17. 17. The Dilemma… Tools Needed12 Stations Available - 14 tools 1. Rough Turnneeded! 2. Finish Turn 3. Groove 4. Thread 5. Radial Endmill 6. Spot Drill 7. Lg. Drill 8. Boring Bar 9. Cut-off Tool 10.Rough Turn (Sub Spindle) 11.Finish Turn (Sub Spindle) 12.Axial Endmill (Sub Spindle) Oops… 13.Cross Hole? 14.Face Groove?
  18. 18. The Solution…Multi-Tool Holders Dual 1” shank Dual ER 32 turning main and Collets main and sub sub Quad turning Dual turning (Y axis required) (Y axis required)
  19. 19. The Solution…Multi-Tool Holders Dual Axial Live Dual Radial Live Tool Tool (Y axis required) (Y axis required) Dual Boring Bar Blade Cutoff Holder (Y axis required) Extra Clearance
  20. 20. More Creative Examples
  21. 21. Tool Holder OrientationAxial vs. Radial
  22. 22. Axial Tool Radial Tool Radial Tool Axial Tool
  23. 23. Radial Tool TMM Turret Axial ToolTools Mount to Turret Face
  24. 24. TMXMY / MYS Turret Axial Tool Radial ToolTools Mount to Outside Edge of Turret
  25. 25. Tool Holder ClearanceBe Careful
  26. 26. Radial Clearance Limited clearance for long tools – especially on the TMM (pictured) Measure before indexing turret Use offset toolholders when possible
  27. 27. Axial Clearance Limited clearance for long tools Clearance issues on both front and back side of turret (main & sub-spindle)
  28. 28. Balancing the Weight
  29. 29. Turret Balance Space toolholders to evenly distribute weight – unbalanced weight could cause premature turret damage and wear
  30. 30. Tool Holder StylesVDI vs. BMT
  31. 31. VDI Turrets Must indicate holders due to allowable play in mounting Some holders have adjustment dials built-in to the holder
  32. 32. VDI Advantages Quick change-over More availability of flexible tool holder options than BMT Versatility – can be used on different turret styles (TMM or MY/MYS) Typically has higher quality bearings than BMT Can be adjusted for increased accuracy
  33. 33. BMT Turrets No need to indicate Locating keys present on turret
  34. 34. BMT Advantages More rigid setup Keyed for quick alignment – but also has no ability for fine adjustment Can be DIY if needed – make your own
  35. 35. Workholding Choices3-Jaw vs. Collet
  36. 36. Advantages3-Jaw Chuck  No part pull-back when closing  Flexible – wide range of sizes  Can clamp out-of-round or irregular shaped parts Disadvantages  Must grease daily  Not as accurate as collets  Difficult to change stock sizes  Serrations can damage part surface
  37. 37. Collet Chuck Advantages  Easy change-over  Chuck diameter is smaller – providing less interference  Increased accuracy  Low maintenance – no grease Disadvantages  More expensive  Separate collet needed for each clamping diameter – requires storage of many collets  Part can pull-back when closing
