HEIDENHAIN iTNC 530 HSCI - Tool Radius and Tool Length Measurement

July 2013 8.13 Touch probe 1553
Tool radius and
tool length
measurement
 With MP6500 bits 1 and 2, specify whether tool radius and tool length
measurements are allowed and whether individual teeth are to be
measured.
 Specify in MP6500 bit 14 if tool measurement with stationary spindle is to
be carried out for tools with the value 0 in the "number of teeth" column
(CUT.) in the tool table. This can be necessary for tools with diamond teeth,
for example.
MP6500 Tool measurement with TT table touch probe
Format: %xxxxxxxxxxxxxxx
Input: Bit 1 –
0: Tool radius measurement allowed
Tool length measurement with rotating spindle
1: Tool radius measurement and individual tooth measurement
disabled
Bit 2 –
0: Tool length measurement with rotating spindle (bit 1=1)
1: Tool length measurement with rotating spindle, only if a tool
radius offset (TT: R-OFFS) has been entered in the tool table
Bit 14 – Tool measurement with number of teeth = 0
0: Tool measurement with rotating spindle
1: Tool measurement with stationary spindle
Oriented
spindle stop
Spindle orientation must be active for individual tooth measurement,
otherwise the tool radius measurement is subject to error:
 Define with MP6500 bit 3 whether the tool is measured with or without
spindle orientation. If MP6500 bit 3 = 1 (without spindle orientation), each
entry in MP6560 that does not equal 0 is not considered.
 With MP6560, specify whether the spindle is to be oriented directly via NC
or through the PLC.
• For spindle orientation directly by NC:
Reset M4012.
• For spindle orientation by PLC:
Enter the number of the M function in MP6560.
The respective positions are transferred as in the "oriented spindle stop" cycle.
M4017 is set during every spindle orientation.
MP6500 Tool measurement with TT table touch probe
Input: Bit 3 –
0: Tool measurement with spindle orientation
1: Tool measurement without spindle orientation.
Individual tooth measurement not possible. Tool radius
measurement possibly faulty.
MP6560 M function for spindle orientation during individual tooth
measurement
Input: –1: Spindle orientation directly by NC
0: Function inactive
1 to 999: Number of the M function for spindle orientation by
PLC
