Measuring Cycles for Turning Machines
6.3 CYCLE982 tool: Measure turning and milling tools
Comments
A special tool is used as the calibration tool and is entered as a turning tool (5xy) with cutting
edge. Calibration is possible with cutting edge positions SL1, SL2, SL3 or SL4. It is usually
shaped (bent) such that it is also possible to approach point P4 for calibration (_MA=1,
_MD=0). Calibration tool: See section "Calibrate tool probe (machine-related)".
However, it is not necessary to calibrate all 4 sides for incremental measurement. The side
that is used for incremental measurement is sufficient. That does not apply to automatic
measurement. Here all 4 points must be calibrated or values entered for automatic central
positioning of the tool to be measured.
Programming example
Calibrate tool probe incrementally
Tool probe 1 is in the machining area and is
oriented parallel to the axis of the machine.
Calibration is to be performed in the minus X
direction and incrementally.
The calibration tool is inserted in the turret as tool T7.
Values of the calibration tool T7 D1:
Tool type (DP1):
Cutting edge position (DP2):
Length 1 - geometry (DP3):
Length 2 - geometry (DP4):
Radius - geometry (DP6):
Values of tool probe 1 in data block GUD6 before calibration:
_TP[0,0] = ?, _TP[0,1] = ?
_TP[0,2] = ?, _TP[0,3] = ?
