What are the reasonable tool life?

Answer:

Production line tool durability should be defined as a class or two class, in order to change the knife at the end of the shift.

The key to meet the production rhythm, in order to make the workshop production balance, durability should be the process of the low. When one process per unit of time sharing to all the expenses is larger, the durability of cutting tools should be low.

For the installation of knife, knife and knife more complex multi machine tools, modular machine tools and automatic processing tools, durability should be higher. The machine can be turned into the vehicle and the ceramic cutter, the tool change time is short, the durability of the optional lower.

For manufacturing, grinding tool is relatively simple, the cost is not high, such as tool, drill, durability can be set lower, whereas the durability should be a little higher, such as milling cutter, broach and gear cutter.

In order to avoid the change of the tool in the process of the same surface, the durability should be higher, at least one knife should be completed.
