3. Cutting Speeds-Determine the time to perform a roughing operation for the main table with the following assumptions: 3/8in diameter carbide end mill Cutting speeds (SFM) i. Cast iron-300 ii. Tool steel-175 Feed per tooth (in) i. Cast iron--.003 ii. Tool steel--.001 7000 inches of tool travel 4. Taylor Tool Life-Determine the number of tools necessary to complete roughing operations for a batch of 1000 parts for the two materials Cast iron (n = .25, C = 350) Tool steel (n = .25, C = 185) 5. of each) Describe the cost/benefit analysis for using carbide tooling vs high speed steel tooling (pros and cons
