Prepare toolpaths

An operation combines the geometry to machine, cutting depths, a tool, and cutting options. The calculated toolpath is the result of those choices.

Choose the target layersCopy Anchor Link

Select only the layers the operation should machine. Separate geometry that needs different cutting treatment into different layers and operations.

See Draw with layers for an example.

Review the cutting depthsCopy Anchor Link

Check where the cut begins and how deep it should go relative to the job's setup. Confirm the stock thickness and origin assumptions before calculating.

Select the toolCopy Anchor Link

Choose the intended cutter from the tool library. Review the effective cutting values and make sure the tool is appropriate for the geometry and material.

Set the cutting optionsCopy Anchor Link

Depending on the operation, review options such as cut side, cutting direction, allowance, and holding tabs. Treat these as decisions about the actual part and setup rather than accepting defaults without inspection.

Calculate and keep the result currentCopy Anchor Link

Calculate after the drawing and settings are ready. The result belongs to that version of the job. Changes can make calculated paths stale; use a current result for simulation, preflight, and export.

Review operation order as well as each individual path. Plan how the part will remain supported throughout machining.

Next: Simulate and export.
