CutMate CNC is a practical milling parameter calculator for machinists, CNC operators, engineers and small-batch workshops. It helps you quickly calculate key cutting parameters before machining, including spindle speed, feed rate, chip load per tooth and cutting speed. Instead of switching between formulas, notes and web calculators, you can enter the material, tool diameter, flute count and machining conditions to get usable reference values in seconds. Key features: • Calculate spindle RPM • Calculate feed rate • Calculate chip load per tooth • Calculate cutting speed • Support common CNC milling scenarios • Get quick trial-cut risk suggestions • Works offline • Simple interface for shop-floor use CutMate CNC is designed for practical reference, not theoretical complexity. It is useful when setting up a new job, checking a rough parameter, comparing tool settings, or making a quick adjustment near the machine. Typical users include: • CNC milling operators • Machinists • Manufacturing engineers • Workshop technicians • Hobby CNC users • Prototype and small-batch makers Cutting conditions vary by machine rigidity, tool quality, workholding, coolant, material batch and machining strategy. Always verify the result with a safe trial cut and adjust based on real machine feedback.
