WebClimb milling is recomm ended over conventional milling as it provides better chip removal, lower tool wear and better surface finish. E nd mills with 4 flutes should be used when po ssible. Generally during milling step overs should be limited to 25% tool diameter and depths of cut 50% of tool diameter to achieve an optimal surface finish. Sawing WebThe ideal feed rate for milling is measured in inches per minute (IPM) and is calculated by this formula: IPM = F x N x RPM Where: IPM = feed rate in inches per minute F = feed per tooth N = number of teeth RPM = …
