An insert map shows your machine's carriage or turret positions in detail for tool changes and setup. It helps you avoid expensive crashes and keeps work accurate.
By Ms Boitumelo Biyela, MD, Bay
An insert map is a simple diagram or chart showing where each tool, insert, or fixture is mounted in your CNC machine. In South African job shops, it’s especially important because many machines are shared between operators. If you skip this step, you risk tool collisions, incorrect offsets, and wasted materials.
For lathes and mills, a clear insert map also helps when you change inserts, regrind cutters, or swap out toolholders. If you can’t quickly check where each tool sits and what offset it uses, you might lose your zero position and have to reset everything, costing hours in lost production. Even just a quick photo on your phone can help, but a formal map is best practice.
Making an insert map is straightforward, but it needs focus. Dont rush the process, or you’ll be hunting for offsets the next time you set up. You want every operator and setter to be able to read and update the same map.
Here’s a step-by-step way to keep your CNC setup clear and safe:
If you’re unsure about mapping tools for a new machine or a complex turret, send us a message using our contact form. We can help you set up a standard layout, show you sample maps, or advise what details your operators should record.
If you use the Feature Tool Crib or need to organise your cutter and insert storage, ask us for advice on shadow boards, pegboards, and records for quick tool changes. Our team can also check your setup during service or training handover if you request it.
A common slip is leaving the insert map out of date after a tool breakage or swap. This leads to lost offsets or even a tool crash if the wrong tool is called up in the programme. Sometimes nobody updates the map after a night shift, and the next job ends up with the wrong setup.
Another issue we see is storing the map on someone’s phone only, or scribbling it on scrap paper that gets lost. For best results, keep one laminated copy by the machine and another digital record for backup, so anyone can find it when needed.
