PROBLEM #1. Directions: write a CNC program. Worth 5
Use for the work piece material: alloy steel Medium Carbon 4140 with hardness of 425. For the tool material use a high speed steel tool. Tool specifications and finished part dimensions are placed on drawing. T3= Drilling diameter ¼”, T2= center drill 1/8”, and T1=milling diameter 1in.
Tools | feed | Cutting speed | RPM | ipm |
T1= Milling 1” diameter high speed steel. N = 2 | ||||
T2 = center drill. Diameter 1/8” | ||||
T3= drill. Diameter ¼” |
Problem #2 Worth 10 points. Use for the work piece material: alloy steel Medium Carbon 4140 with hardness of 425. For the tool material use a high speed steel tool. Tool specifications and finished part dimensions are placed on drawing. Remember. T3= Drilling diameter ¼”, T2= center drill 1/8”, and T1=milling 0.5in.
Tools | feed | Cutting speed | RPM | ipm |
T1= Milling 0.5” diameter high speed steel. N = 2 | ||||
T2 = center drill. Diameter 1/8” | ||||
T3= drill. Diameter ¼” |
