Measuring Cycles for Turning Machines
6.3 CYCLE982 tool: Measure turning and milling tools
Prerequisite
The tool probe must be calibrated.
The approximate tool dimensions must be entered in the tool offset data:
Tool type, cutting edge position on turning tools, radius, length 1, length 2.
The tool to be measured must be active with its tool offset values when the cycle is called.
For a milling cutter, the 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").
