Suppressing touch probe monitoring with M141

Application

In conjunction with the touch probe cycles 3 MEASURING or 4 MEASURING IN 3-D, if the stylus is deflected, you can retract the touch probe in a positioning block with M141.

Description of function

Effect

M141 is in effect blockwise for straight lines and takes effect at the start of the block.

Application example

NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.

Change the following contents as needed:

  • Tools
  • Cutting parameters
  • Feed rates
  • Clearance height or safe position
  • Machine-specific positions (e.g., with M91)
  • Paths of program calls

Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.

In addition, test the NC programs using the simulation before the actual program run.

 
Tip

With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.

; Retract with M141

In Cycle 3 MEASURING the control probes the X axis of the workpiece. Since no retraction distance MB is defined in this cycle, the touch probe stands still after the deflection.

In NC block 16 the control retracts the touch probe against the probing direction by 20 mm. M141 suppresses monitoring of the touch probe.

Without M141 the control issues an error message as soon as you move the machine axes.

Note

 
Notice
Danger of collision!
The miscellaneous function M141 suppresses the corresponding error message if the stylus is deflected. The control does not perform an automatic collision check with the stylus. Based on these two types of behavior, you must check whether the touch probe can retract safely. There is a risk of collision if you choose the wrong direction for retraction.
  1. Carefully test the NC program or program section in the Single Block mode
