Tool Changing Time for each Tool given min production time Formula

Tool Changing Time and its effect on Production.

Every time a tool has certain life within which it can perform satisfactorily, and thus replacement or re-sharpening is required to perform once tool life exceeds. Cutting or machining action is also required to pause for a certain time. An increase in cutting speed or feed rate will reduce tool life and thus frequent tool changing will be desired. This unplanned and frequent interruption in machining will impose loss to the industry.
