What manufacturers typically customise
| Customisation | Why it matters |
|---|---|
| Program header with part, revision, operation and programmer | Traceability and correct program selection |
| Tool list with lengths, holders and stick-out | Faster setup and fewer tool errors |
| Safe start and restart blocks | Safe mid-program restarts after tool breakage |
| Probing macros for setup and in-process checks | Automatic work offsets and quality checks |
| Tool life and breakage detection calls | Unattended machining reliability |
| Program naming and numbering rules | DNC and MES integration |
| Estimated cycle time in the header | Planning and quoting |

Manufacturers with several machines benefit from a post family: one shared code base with machine-specific settings. Programs look the same on every machine, and operators move between machines without surprises. Changes to shared behaviour are made once.
Restart-friendly output
Every operation can begin with a complete, self-contained block (tool, offset, spindle, coolant, work offset, positioning), so operators can restart safely from any operation after a tool break or inspection stop.
Customer and industry requirements
Aerospace, medical and automotive customers may require specific program formats, documentation or approvals. Custom posts produce this automatically, avoiding manual paperwork.
A customised post processor turns your shop's best practices into automatic behaviour.
