Linear Tool Changer (Type 2)

Two types of linear tool changer are supported with some different control logic inputs and outputs. Please see both Type 1 and Type 2 logic explanations and see the one that fits best to your machine requirements.



Selecting the tool changer


In the Tool Changer window select the tool changer and double click for settings.






Tool Changer Inputs and Outputs


INPUTS


  • Tool Changer – Input 1 for Spindle drawbar Status (Low for clamped and High for un-clamped)
  • Tool Changer – Input 2 for Tool in place Status (Alarm when Low)
  • Tool Changer – Input 3 for Dust Hood UP OK signal (High means hood UP)


OUTPUTS


  • Chuck Clamp M10/M11 for spindle drawbar clamp and un-clamp (Low to clamp and High to un-clamp)
  • Tool Changer – Output 1 to move Dust Hood UP/DOWN (When HIGH the hood will move UP)
  • Tool Changer – Output 2 for air return (Will stay high for 6 seconds after tool change)


INFORMATION: From MASSO software v3.48, if "Tool Changer - Output 2" is not assigned as an output in F1-Setup screen then the 6 second delay is automatically ignored by the logic.




Tool Changer logic


When a tool change command is received, the tool changer logic works in the followings steps:


  1. Spindle is turned OFF and system waits for the spindle to stop as per the spindle "Spin down delay" value in the spindle settings.
  2. System checks if the current tool in the spindle is setup in a slot is the F4-Tools screen, else gives an error.
  3. System checks if the tool to load is setup in a slot is the F4-Tools screen, else gives an error.
  4. Z Axis moves up to the homing position.
  5. "Tool Changer - Output 1" goes HIGH to move Dust Hood UP, then system waits for 6 seconds for the "Tool Changer - Input 3" (Dust Hood UP OK) signal to go HIGH, else gives an error.
  6. X & Y Axis moves to tool unload position.
  7. Z Axis moves down to the tool unload position.
  8. "Chuck Clamp M10/M11" goes HIGH to unclamp the tool, then system waits for 6 seconds for the "Tool Changer - Input 1" (Spindle draw bar Status) signal to go HIGH, else gives an error.
  9. Z Axis moves up to the tool unload clearance position.
  10. X & Y Axis moves to new tool load position.
  11. Z Axis moves down to the tool load position.
  12. "Chuck Clamp M10/M11" goes LOW to clamp the tool, then system waits for 6 seconds for the "Tool Changer - Input 1" (Spindle draw bar Status) signal to go LOW, else gives an error.
  13. Axis moves to slide out the new tool.
  14. Z Axis moves up to the homing position.
  15. "Tool Changer - Output 1" goes LOW to move Dust Hood DOWN, then system waits for 6 seconds for the "Tool Changer - Input 3" (Dust Hood UP OK) signal to go LOW, else gives an error.
  16. "Tool Changer - Output 2" goes HIGH for 6 seconds (For spindles with air return requirment).


INFORMATION: From MASSO software v3.48, if "Tool Changer - Output 2" is not assigned as an output in F1-Setup screen then the 6 second delay is automatically ignored by the logic.


INFORMATION: All input & output signals can be easily inverted by selecting the input or output in the list and pressing the space-bar key on the keyboard to invert the signal. These settings are automatically saved.


INFORMATION: Make sure to assign each tool into a tool slot in the F4 - Tools & Work offset screen else on a tool change command if the tool is not set in a slot you will get a tool error alarm.
