Checking the radius of the replacement tool with M108
Application
If you program M108 before inserting a replacement tool, the control checks the replacement tool for any radius deviations.
Description of function
Effect
M108 takes effect at the end 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.
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.
11 TOOL CALL 1 Z S5000 | ; Insert the tool |
12 M101 M108 | ; Activate automatic tool change and radius checking |
The control exchanges the tool and activates the automatic tool change and radius checking in the next NC block.
If the maximum tool age of the tool expires during machining, the control inserts the replacement tool. The control checks the tool radius of the replacement tool based on the M108 miscellaneous function defined previously. If the radius of the replacement tool is greater than the radius of the tool being replaced, the control issues an error message.
Without M108 the control will not check the radius of the replacement tool.
Note
M108 is also used to reset M107 (#9 / #4-01-1).
