User-entered cutting-condition arithmetic
Milling cutting parameters
Inputs
Effective cutting diameter used for spindle-speed arithmetic.
User-selected surface cutting speed; this workspace does not recommend it.
Engaged cutter tooth count used for the stated feed relation.
User-selected feed per tooth; this workspace does not select it.
Stated engaged axial cut depth.
Stated engaged radial cut width.
User-entered material/process force coefficient; no lookup is used.
User-entered machine efficiency from 0 to 100 used only in the stated power arithmetic.

When
- Face-milling arithmetic
- Constant engagement
- Inputs user-selected
- Theoretical process values
Don’t
- This is face-milling reference arithmetic using user-entered cutting conditions, specific force, and efficiency. It excludes selection of speed/feed/tool/material parameters, tooth engagement variation, radial chip thinning, cutter geometry, runout, acceleration, spindle torque limits, rigidity, chatter, coolant, tool wear, fixture limits, thermal effects, surface quality, and process qualification.
