CNC Post Processors

CAM-to-CNC Automation Using Custom Post Processors

The post processor sits at the exact point where engineering data becomes shop-floor instructions. That makes it the ideal place to automate everything that happens next.

What a post can generate besides G-code

  • Setup sheets in HTML or PDF with tools, offsets and images.
  • Tool lists in CSV or XML for presetters and tool cribs.
  • Job data (cycle time, tools, material) for MES or ERP.
  • Log files recording who posted what and when.

An automated flow

StepAutomated by
Name program from part number, revision and operationPost processor
Write NC file to the machine's DNC folderPost processor or script
Export tool list to presetterPost processor
Publish setup sheet to shop-floor screenPost processor + web app
Update job status in MESAPI call after posting

Example: tool list export

tool,description,diameter,stickout,holder
1,Endmill 16 rougher,16.0,45,BT40-ER32
4,Drill 8.5 carbide,8.5,60,BT40-HYD12
7,Tap M10x1.5,10.0,55,BT40-TAP

Zero-edit programs

The foundation of automation is that posted programs run without editing. Only then can they flow directly to machines, presetters and MES without someone opening and changing them.

Keep it controlled

  • Send programs only to approved folders; never overwrite running programs.
  • Keep NC file revisions linked to CAM file revisions.
  • Log every post and transfer for traceability.
A good post processor finishes programming; a great one starts production.
