This parameter shows the spindle speed in revolutions per minute (RPM) . You can set the direction of the spindle rotation to the clockwise (CW) or counterclockwise (CCW).
SURFCAM uses the following formulas to calculate the Spindle Speed.
|
|
Inches: |
Spindle Speed = (Surface Speed*12) / (3.14159*Diameter) |
|
|
Millimeters: |
Spindle Speed = (Surface Speed*1000) / (3.14159*Diameter) |
Surface Speed
The Surface Speed value in the formula is from the Material Library. The value refers to the material that you cut and the material of the tool.
Diameter
The Diameter value in the formula is the value of the Tool Diameter parameter in the Tool Information tab.
To override the Spindle Speed value that was calculated, enter a new value. SURFCAM again calculates the Surface Speed, the Feed Chip Load, and the Plunge Chip Load values.
