* = 12,500 RPM

 

NOTE: To eliminate rewelding increase the feedrate or change to a single edge tool

If using a downcut spiral and chip rewelding occurs, cut a slot in your spoilboard to allow the chips a place to expand

Incorrect chiploads can lead to knife marks occurring

 

FORMULAS: Chip Load = Feed Rate / (RPM x # of cutting edges)

Feed Rate = RPM x # of cutting edges x chip load

Speed (RPM) = Feed Rate / (# of cutting edges x chip load)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

NOTE: When chip rewelding occurs while cutting soft plastic, increase feedrate or go to a single edge tool.

Incorrect chiploads can result in cratering

FORMULAS: Chip Load = Feed Rate / (RPM x # of cutting edges)

Feed Rate (IPM) = RPM x # of cutting edges x chip load

Speed (RPM) = Feed Rate / (# of cutting edges x chip load)

DEFINITIONS: IPM = Inches Per Minute

IPR = Inches Per Revolution
