QUESTION 2 Tool life is the most important factor in the evaluation of machinability. Tool life can be defined as the period of time which the tool cuts effectively and efficiently. A cutting tool should have a long tool life. On the other hand, the cutting speed decreases the tool life due to the abrasive action that occurs between the cutting tool and materials. The increase in cutting speed will decrease the machining time, thus reduce the total machining cost. Justify what actions should be taken to increase the tool life and at the same time shorten the machining time.

Machining Processes and Machine Tools

Machining is represented as the process in which an excessive amount of substance is eliminated from the particular element in the form of pieces. In machining, cutting tools such as rotary tools, lathe, drill press, grinder, chop saw, welders, and many more are applied to get the desired shape. As compared to other manufacturing processes, machining is precise and versatile.
