Starting cutting values for WDN0204
Calculated for a Ø2 mm cutting diameter and 4 flutes. Radial engagement is taken as ae = 0.5×D and axial depth of cut as ap = 1×D. Values assume a carbide tool and medium duty conditions; machine rigidity and workholding change the result. These are calculated reference values. They change considerably with the machine, tool holder, clamping and the result you need; applying them remains the responsibility of the user.

About this size
- Square end mill; used for side milling, slotting and square shoulders. The cutting corner is sharp, so stress concentrates there and edge chipping usually starts at the corner.
- 2 mm sits in the micro machining range: reaching the target cutting speed requires very high spindle speed and most machines hit their rpm ceiling, so in practice Vc stays below target. In this range holder runout matters more than the tool itself.
- Length of cut to diameter ratio 3; standard configuration. At full engagement deflection becomes measurable and an allowance should be left on the side wall.
These notes are derived from the geometry and ratios of this size and are general in nature. Machine, holder, clamping and coolant conditions change the outcome considerably.
