Measuring Cycles for Turning Machines
6.3 CYCLE982 tool: Measure turning and milling tools
Requirements
For incremental measurement, the tool probe must be calibrated in the measuring axis and
direction in which measuring will be performed.
The tool T to be measured must be called with tool offset (D number).
The tool type is entered in the offset data.
For a milling cutter, setting data SD 42950: TOOL_LENGTH_TYPE = 2 must be set (length
calculation as for turning tool).
For milling tools, the tool spindle must be declared the master spindle. For a drill, SD 42950:
TOOL_LENGTH_TYPE = 0 is also possible (refer to Chapter "Measuring drills – special
applications").
