Siemens alarm 61704: Machined part contour missing

What it means

A stock-removal cycle expects the description of the finished part contour but none is available at the call position. Contour turning works by comparing finished part against blank; without the part contour the comparison is impossible. Provide the contour subroutine and reference it correctly in the cycle call.

Likely causes

• Finished-part contour subroutine absent from program storage
• Contour label/name mismatch in the cycle call
• Contour blocks executed before the cycle instead of stored as subroutine
