Working safely

PureCutCNC helps you inspect a job; it does not certify that the job is safe to run. Preview, simulation, warnings, and G-code export are verification aids. The operator remains responsible for the machine, workholding, stock, tooling, controller setup, and physical test procedure.

Main idea

Section titled “Main idea”

Treat every generated toolpath as a claim to inspect, not permission to cut. A path that looks reasonable on screen can still be wrong for the installed cutter, stock position, fixture, controller mode, work offset, or machine limits.

PureCutCNC does not decide safe feeds, spindle speed, tool limits, controller capabilities, or machine setup for you. Keep project units, origin, machine selection, and post-processor choice explicit, because each affects the physical motion described by the exported program.

Review before export

Section titled “Review before export”

Before exporting, confirm:

  • The project units and stock dimensions match the material at the machine.
  • The project origin and the machine work offset use the same zeroing plan.
  • Every selected operation targets the intended geometry and has the intended tool.
  • The tool diameter, length, feed, plunge feed, spindle speed, and machine capability match the actual setup.
  • Tabs, clamps, clearance heights, entry moves, retracts, and rapid moves are suitable for the fixture and tool.
  • Every clamp is shown. Hidden clamps are left out of the clamp clearance checks; see Feature tree and properties.
  • Warnings are understood and resolved rather than dismissed to make output look valid.

Use the export dialog’s operation checklist to verify exactly which valid operations will be included. Do not infer the exported set from a tree visibility state alone.

Review the generated result

Section titled “Review the generated result”

Use Sketch, 3D view, and Simulation to inspect a change before export. Check material removal, depth, entries, exits, rapids, and clearance around fixtures. When a feature, tool, origin, machine, or operation changes, regenerate and review again; a previous preview no longer answers the new question.

After export, open the G-code in the controller or another appropriate viewer. Check the program against the selected machine, origin, expected units, tool changes, and safe-Z behavior before it reaches the machine.

Test at the machine

Section titled “Test at the machine”

Set up the real stock and workholding, establish the work offset, and verify the installed tool. Use the machine’s normal dry-run or air-cut procedure with the spindle off before allowing the tool to contact material. Stay ready to stop the machine while proving a new or changed job.
