PER PART REDUCED BY Increasing the feed by 278% has decreased the total hours of machine time by 100 hours $0.15 $0.61 gaining manufacturing capacity; this factored with the hourly shop rate has resulted in the (19.55%) (79%) largest portion of the savings. $0.10 With a tool life of 500 parts compared to 140 parts or a 357% improvement in tool life $0.04 (12.51%) equates to less time dedicated to changing tools to keep the job running. (5.47%) Increasing the material removal rate by .28 cubic inches or 275% requires less time in the cut and a reduced use of coolant. www.kyocera-sgstool.com
