Machine details that shape the post
| Machine detail | Post impact |
|---|---|
| Tool changer type (arm, umbrella, carousel) | Pre-select support, tool change position |
| Maximum spindle speed and feed | Output limits and warnings |
| Travel limits | Range checks before posting |
| Coolant options | Flood, mist, air, through-spindle codes |
| Probing system | Setup and in-process macro calls |
| Controller options | High-speed mode, extended offsets, macros |
Core output requirements
- Safe start block that cancels modal states.
- Reliable tool change with length offset.
- Arcs in all three planes with correct format.
- Canned cycles instead of expanded moves.
- Cutter compensation with safe lead-in and lead-out.
- High-speed mode around 3D finishing.
- Clean program end and return to a safe position.
3-axis post checklist
[ ] Safe start: G90 G17 G40 G49 G80 (or controller equivalent)
[ ] Tool change + pre-select
[ ] G43 H matches tool
[ ] Work offsets incl. extended
[ ] Arcs G17/G18/G19 verified
[ ] Drill, peck, tap, bore cycles verified
[ ] G41/G42 lead-in / lead-out
[ ] High-speed mode on/off
[ ] Program end: spindle, coolant off, safe positionRestart and multi-part output
Restart-friendly operation blocks and multi-part (multiple work offset) output are two of the most valuable 3-axis customisations for production shops.
The best 3-axis posts make routine work faster and safer every single day.
