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
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).
