Calculating the correct spindle speed (RPM) and feed rate is crucial for efficient milling:
- Spindle Speed (S): Calculated using the formula S=VcπDS=πDVc, where VcVc is the cutting speed (surface feet per minute or meters per minute), and DD is the tool diameter.
- Feed Rate (F): Determined by F=z×S×FzF=z×S×Fz, where zz is the number of teeth (flutes), SS is the spindle speed, and FzFz is the feed per tooth.
These calculations help optimize cutting efficiency and prolong tool life.
