Use a definição do frontmatter como significado controlado para setup, usinagem e inspeção.

Fórmula / Regra

• Rough machining prioritizes stable material removal and leaves a controlled allowance for later finishing.
• Increase removal only after chip evacuation, spindle load, and workholding stability remain predictable.

Faixa típica

• Leave a stable allowance for finishing instead of consuming the whole stock in one aggressive roughing pass.
• For thin walls or weak fixtures, reduce radial engagement before raising feed or axial depth.

Cenários de chão de fábrica

• Open up chip evacuation and spindle load margin before increasing stock removal on the next lot.
• Split roughing into predictable stages when the workholding or part stiffness changes across the program.

Erros comuns / Solução de problemas

• If chatter rises during roughing, reduce engagement or improve support before cutting speed is increased again.
• If roughing leaves unpredictable stock, review tool deflection, wear, and path overlap before blaming finishing.
