Have you ever been called to the shop to troubleshoot a probe routine only to find out the operator had put an offset in the Z axis Common Work Shift when he proofed the machining program and forgot to remove it? You can add one line of code in your probe programs to prevent this problem.
The code #5203=0(CLEAR COMMON Z) is an important safety feature that you should include in all probe programs. If the operator had put an offset in the Z axis Common Work Shift and then runs the probe, the offset is added to the coordinate system and the probe will probably error because it will miss the part.
However, if the operator notices the offset, presses Slide Hold, clears the offset and then presses Cycle Start the machine will rapid the amount of the offset and wont be in protected positioning mode. In any event, this one line of code will prevent wasted time.
To use this tip insert #5203=0(CLEAR COMMON Z) before calling G54 and positioning the probe to the part. Also, don't put this code in the machining program. If the operator expects the tool to position above the part and you have cancelled his Z axis Common Offset a crash can occur. |
