Technical Tools
Both tools share one dataset: material groups follow the ISO 513 classification and cutting speed ranges are defined per tool material and coating. From a result you can go directly to the matching size row.
Cutting Parameter Calculator
Spindle speed (n), feed per tooth (fz), table feed (vf), material removal rate (Q) and required spindle power from material group, cutting diameter and flute count. Chip thinning is corrected automatically when radial engagement is below half the diameter.
Cutting Parameter CalculatorTool and Coating Selector
Tool geometry, flute count and coating recommendations based on material, operation and engagement. Warnings are rule based and every recommendation is shown with its reasoning.

The formulas behind the calculation and the selection rules are covered in detail in the guides.

Results and recommendations are starting values. Machine rigidity, holder, clamping and coolant conditions change the outcome considerably; values are to be verified and adapted on the workpiece.
