If you need to cut a slot in a piece of low carbon steel what tool material would you use to yield the fastest/highest production rate?

Assuming the cutter has a diameter of .500”, what spindle speed would you select?

Assuming the cutter is a high speed steel 4 flute end mill rotating at the recommended maximum RPM for the tool material/material combination and the recommended feed, what would the federate be and how long will it take to make a single pass if the length of the slot is 24” long overall.

Solution

Speed- 60-100 (Selected from the chart Table 10)

Feed-0.002 inch/tooth (Table 10 A)

Time: 0.048

Coolant: water soluble oil

Recommended to use the maximum cutting speed of 100
