Touch Probe Cycles: Automatic Workpiece Inspection | MEASURE HOLE (Cycle 421, DIN/ISO: G421)
Q330 Tool for monitoring?: Definition of
whether the TNC is to monitor the tool (See "Tool
monitoring", page 588). Input range 0 to 32767 .9,
alternatively tool name with maximum of 16
characters
0: Monitoring inactive
>0: Number or name of the tool that the TNC used
for machining. You are able to apply a tool via soft
key directly from the tool table.
Q423 No. probe points in plane (4/3)?: Define
whether the TNC should measure the stud with 4
or 3 probing points:
4: Use 4 measuring points (standard setting)
3: Use 3 measuring points
Q365 Type of traverse? Line=0/arc=1: Definition
of the path function with which the tool is to move
between the measuring points if "traverse to
clearance height" (Q301=1) is active:
0: Move in a straight line between machining
operations
1: Move in a circular arc on the pitch circle
diameter between machining operations
Q498 Reverse tool (0=no/1=yes)?: Only relevant
if you have entered a turning tool in parameter
Q330 before. For proper monitoring of the turning
tool, the TNC requires the exact working condition.
Therefore enter the following:
1: Turning tool is mirrored (rotated by 180°), e.g.
by Cycle 800 and parameter Reverse the tool
Q498=1
0: Turning tool corresponds to the description in
the turning tool table (toolturn.trn), no modification
by e.g. Cycle 800 and parameter Reverse the tool
Q498=0
Q531 Angle of incidence?: Only relevant if you
have entered a turning tool in parameter Q330
before. Enter the angle of incidence between
the turning tool and the work piece during
machining, e.g. from Cycle 800 parameter Angle
of incidence? Q531. Input range: -180° to +180°
