Write the NC part program for the part. Holes are threaded and requires two tools; T1 is a 0.5" HSS drill bit and T2 is a 0.5" tapping bit. The rest of the features are cut using a 0.75" HSS milling tool, T3. Feed rate and spindle speed are 10 ipm and 2000 rpm. The material is low- carbon steel. Part thickness is 0.5”. Use dotted lines two show the path of tools movements. Set up proper operation conditions as discussed in the class today.
