Use the feed rates and the number of passes in the program to calculate the time it will take. If the roughing pass is running at 2 inches per minute and the part is 6 inches in size, the section will take 12 minutes. Estimate the other passes, including the finishing cuts. Add that and estimate about 30 seconds per tool change to get an estimate of total time. References. Modern machine Shop ...
