What would increase the tool life in machining operations?

Optimizing cutting speeds and feeds, as well as using coolant effectively, significantly contributes to increasing tool life in machining operations. By setting the appropriate cutting speeds and feeds, the cutting tool engages the workpiece in a manner that minimizes wear and tear. This is essential because excessive speeds or feeds can lead to overheating, which can diminish the tool’s hardness and lead to premature failure.

Additionally, the effective use of coolant helps in several ways. It reduces friction and heat buildup at the cutting interface, which in turn lowers the wear rate on the tool. Coolants also assist in removing chips from the cutting area, which can otherwise cause damage to both the tool and the workpiece. By managing these variables appropriately, machinists can enhance the durability and performance of cutting tools, thereby extending their life and reducing the frequency of tool changes.

In contrast, using a softer material for tooling would generally lead to quicker degradation under machining conditions, as softer materials may not withstand the stresses involved in cutting operations. Changing tools every hour does not necessarily correlate with increased tool life; while regular changes can mitigate issues, it can also be inefficient and may not maximize the potential life of the tool if it’s not worn out. Lastly, implementing manual cutting tends to be less efficient
