Before the machine session
- Post completed and all test programs simulated.
- Machine warmed up, referenced and in good mechanical condition.
- Tools measured and loaded; work offsets set.
- Operator and programmer available; emergency stop procedure agreed.
Commissioning steps
| Step | Purpose |
|---|---|
| 1. Header and tool change test | Confirm safe start, tool change and offsets |
| 2. Air cut above part | Verify motion with Z offset raised |
| 3. Single block critical moves | Rotary positioning, cycles, tilted planes |
| 4. TCP / tilted plane check | Touch a known point with rotary axes tilted |
| 5. Cycle checks | Drilling, tapping, probing on scrap material |
| 6. First-part cut | Measure features, surface and cycle time |
| 7. Sign-off | Record version, results and approvals |
Checking TCP on the machine
(Touch a probe or indicator tip at a known point)
(Rotate A/B with TCP active: the tool tip should stay on the point)
G43.4 H1
G0 A0. C0.
G1 A30. F500.
G1 A-30.
G49If the tip moves away from the point while rotating, the kinematic data in the controller or post needs correction.
Handover
- Approved post version stored under version control.
- Post settings and options documented for programmers.
- Known limitations listed clearly.
- Support channel agreed for future changes.
Commissioning is where the post processor earns the machine operator's trust.
