Multi-Axis Turning | Hurco IMTS 2012 Multi-Axis Turning | Hurco IMTS 2012 Presentation Transcript

  • Multi-Axis Turning Getting back to basics…
  • 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)
  • TMX 2-axis ( X, Z, W )Programmable Tailstock Z-Axis X-Axis Programmable Tailstock
  • 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
  • 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)
  • Visualize Movement Click for Video Y-Axis Perpendicular to X-axis
  • C-Axis Milling Y-Axis Milling(always points to center) (allowed to move laterally)
  • C-Axis Drilling Y-Axis Drilling(always points to center) (allowed to move laterally)
  • Let’s Talk PartsExamples…
  • TMM Parts All features on centerline C-axis & X-axis correlation for axial milling of flats Click for Video
  • TMM Parts C-axis & X-axis correlation for axial milling off center circles Click for Video
  • MY/MYS Parts Features can be off-centerline of the workpiece Flats can be milled using the Y-axis Click for Video
  • Real-World ExampleShow me the money…
  • 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
  • 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
  • Multiple OperationsConserving Turret Stations
  • 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?
  • 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)
  • 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
  • More Creative Examples
  • Tool Holder OrientationAxial vs. Radial
  • Axial Tool Radial Tool Radial Tool Axial Tool
  • Radial Tool TMM Turret Axial ToolTools Mount to Turret Face
  • TMXMY / MYS Turret Axial Tool Radial ToolTools Mount to Outside Edge of Turret
  • Tool Holder ClearanceBe Careful
  • Radial Clearance Limited clearance for long tools – especially on the TMM (pictured) Measure before indexing turret Use offset toolholders when possible
  • Axial Clearance Limited clearance for long tools Clearance issues on both front and back side of turret (main & sub-spindle)
  • Balancing the Weight
  • Turret Balance Space toolholders to evenly distribute weight – unbalanced weight could cause premature turret damage and wear
  • Tool Holder StylesVDI vs. BMT
  • VDI Turrets Must indicate holders due to allowable play in mounting Some holders have adjustment dials built-in to the holder
  • 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
  • BMT Turrets No need to indicate Locating keys present on turret
  • 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
  • Workholding Choices3-Jaw vs. Collet
  • 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
  • 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
