Interpreting the feed rate as mm/rev with M136

Application

With M136, the control interprets the feed rate as millimeters per spindle revolution. The feed rate depends on the spindle speed.

Description of function

Effect

M136 takes effect at the start of the block.

In order to reset M136, program M137.

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.

; Switch interpretation of the feed rate to mm/rev

With M136 the control interprets the feed rate as millimeters per revolution.

Without M136 the control interprets the feed rate as millimeters per minute.

Notes

  • In NC programs based on inch units, M136 is not allowed in combination with FU or FZ.
  • When you move the axes while M136 is active, the control will display the feed rate in mm/rev in the Positions workspace and on the POS tab of the Status workspace.
  • The Positions workspace

  • The POS tab

  • M136 is not possible in combination with an oriented spindle stop. The control cannot calculate the feed rate because the spindle does not rotate during an oriented spindle stop, such as when tapping.
