Milling Speed and Feeds Calculator
- Tool Diameter: Enter the diameter of your milling tool.
- Surface Speed: Input the surface speed in SFM (Surface Feet per Minute), or refer to the provided table.
- Spindle Speed: The calculator automatically computes the RPM based on the given parameters using the formula (12 * SurfaceSpeed) / (PI * CutterDiameter).
Feed Rate Calculator
- Spindle Speed: Enter the spindle speed in RPM.
- Feed/Tooth (Chipload): Input the chipload (inches per tooth) or IPT.
- Number of Flutes (Teeth): Specify the number of flutes on your tool.
- Feed Rate: The calculator instantly calculates the feed rate in IPM (inches per minute) using the formula Chipload * NumberFlutes * RPM.
