CNC Software with ShopMill 1.5 SP4
Good results can be achieved by applying the following measures:
The circle segment to be measured should ...
- be free of remains of previous machining operations - burrs, etc.
- the production technology used should guarantee a circular shape that is as precise as possible,
and which should have the lowest possible surface roughness!
- be measured with high quality probes, which means that the probe balls must have a spherical
shape
that is as homogeneous as possible.
- be measured using the 4-point measurement version (_PRNUM=1xxx).
- be measured using an up-to-date calibrated probe.
Information on measuring tools with CYCLE982 in conjunction with CUTMOD:
The command CUTMOD = -2 is internally programmed in the CYCLE982 measuring cycle. This is kept
after the cycle has been called; this means that the value that was programmed before the cycle call is no
longer valid.
Note on CYCLE998 or on the function "Align edge" in the JOG mode from MC 07.05.06.00 onwards
Alarm 61189, "Invalid rotary axis positions" has, in conjunction with measuring cycles, the following
significance from version
MC 07.05.06.00 onwards:
Alarm 61189 can be output for the "1-angle measurement with CYCLE998" in the automatic mode and for
the function "Align edge" when measuring in JOG, together with the rotary axis correction target!
When this alarm is output, no correction is made to the zero offset of the selected rotary axis - the
measurement program must be cancelled with "RESET"!
Cause:
The measured physical angle does not lie in the working plane or is not vertical to this. As a
consequence, the result of the 1-angular measurement is sub-divided into several result components,
which cannot be corrected in a rotary axis with only one degree of freedom (e.g. rotary axis C rotates
around Z)!
Remedy:
Correction target, instead of "Correction in the rotary axis", select -> "Correction in the coordination
rotation".
Note when measuring in the JOG mode:
Modified behavior when calibrating the workpiece probe (radius):
New adjustable parameter to transfer the determined radius value into the tool correction
parameter radius of the active workpiece probe when measuring in JOG:
_CBIT[15]=0: No transfer (standard value)
_CBIT[15]=1 The determined radius value is transferred
Note: _CBIT[15] is effective unchanged - also in the automatic mode (CYCLE976)!
Commissioning measuring cycles for SINUMERIK 840D sl, SW 1.x
Preconditions
- The software release of the measuring cycles, which are to be commissioned, must be on the CF card.
Otherwise, no additional software tools are required for commissioning.
- Before starting commissioning, it must be carefully ensured that the existing state is archived; if required,
read-out the series commissioning archive.
Step 1 - Machine data settings
The following machine data apply when using Siemens standard and measuring cycle packages.
