What causes Siemens SINUMERIK alarm 112099?

Malformed or incomplete contour geometry definition in the part program. Insufficient memory available for contour pocket calculation. Invalid pocket parameters or conflicting pocket depth specifications. Corrupted NC program or syntax error in contour definition block. Machine control software version incompatibility with contour pocket cycle.

How do I fix Siemens SINUMERIK alarm 112099?

1. Review the NC program syntax for the contour pocket block; verify all required parameters are defined and geometrically valid before the pocket call 2. Clear the CNC memory cache and restart the control system; check available memory in Diagnostics menu under Storage 3. Verify the contour geometry is closed and properly dimensioned; use the program editor to step through the contour definition line-by-line 4. Reduce contour pocket complexity by breaking the operation into multiple smaller pockets or simplifying the geometry profile 5. Check the machine's software version in the System Information menu and compare against Siemens release notes for known contour pocket issues; perform a software update if available
