CNC Machine Maintenance Log

CNC Job and Tooling Sheet
A free printable CNC job sheet — stock, origin, workholding, a tool list with the feeds and speeds you ran, and a run record for one job on a router, mill or laser.

One page. Choose your paper size — both versions are laid out identically, so neither one gets shrunk to fit.
Print it and write on it

The fillable versions have real form fields — open them in any PDF reader, type into them and save. Printing help.
What this sheet is for
Run a repeat job on the first attempt, because the tool list and the numbers that worked last time are on one sheet with the program name.
Who it is for
Small CNC shops, makers with a desktop router or mill, laser cutters, and makerspaces where more than one person sets up the same machine.
How to use it
- Fill in the stock, origin and workholding before touching the machine.
- List every tool in the order the program calls it, with the feed, speed and depth you actually set.
- Log each run with the quantity, cycle time and anything scrapped.
- When a number changes, note why in the run record rather than overwriting the tool list.
- File the sheet with the program so the next order starts from it.
What is on the sheet
One page, top to bottom:
Printed under the title: One CNC job on paper before the spindle turns — stock, origin, workholding, and every tool with the numbers you ran it at.
The feeds, speeds and depths of cut are yours: they depend on your machine, your tooling, the material and how it is held, and the tool maker's data is where they start. This sheet is where the numbers that actually worked are kept with the job.
Write-on lines: Job / part · Customer or project · Date · Machine · Material & stock size · Program / file name · Post / controller · Quantity · Work offset & origin · Workholding · Z reference · Coolant / air
Tool list — one line per tool number, in the order the program calls them
Table, 5 rows: T no. · Tool · Dia. · Stick-out · Holder · Feed · Speed · Depth / step · Notes
Run record — each setup or batch run of this job
Table, 4 rows: Date · Op / program · Qty run · Cycle time · Scrapped · Why / what changed · Operator
Questions
Why does the sheet not suggest feeds and speeds?
Because there is no right number without knowing your machine, your tooling, the material and how it is held. Tool makers publish starting points for their own cutters; your machine tells you the rest. The sheet records what you settled on, so it is not worked out twice.
Can I use it for a laser cutter?
Yes. Treat the tool list as your power, speed and pass settings per material, and the run record works the same way.
