Checklist: CNC startup and preparation
Control points from machine start to first approved item
Use this checklist each time a CNC machine is set up for a new task, or a new program is to be run for the first time. It gathers the control points that prevent the most common errors: wrong zero point, loose clamping and undetected collisions.
§Before startup
- 01Check that the machine is lubricated and has completed its daily inspection
- 02Check that correct tool is in the correct stations
- 03Verify component drawing and program version against the work order
- 04Review the program in simulation for collisions
§Clamping and zero point
- 01Clean clamping and item for chips and oil
- 02Clamp the component firmly and verify it cannot move during machining
- 03Measure null point and confirm it against the drawing's reference point
- 04Double-check tool lengths in the tie-rod
§First drive
- 01Run the program in single block or at reduced speed the first time
- 02Keep hand at emergency stop during first movements
- 03Stop and measure the first item before series production starts
- 04Approve first item against drawing dimensions before more are run
