How can improper tool selection affect CNC milling?

• A. It makes the milling faster
• B. It leads to premature tool wear and poor surface finish
• C. It has no effect on the outcome
• D. It is beneficial for small jobs

Answer: (B)

Improper tool selection in CNC milling can lead to premature tool wear and poor surface finish due to several reasons. When a tool is not suited for the material being machined or the specific operation being performed, it can quickly degrade. For instance, using a tool with the wrong geometry, material, or coating can cause excessive heat generation, leading to rapid wear and even tool failure. Furthermore, the tool may not effectively cut the material, resulting in an uneven surface finish, which is crucial for meeting quality standards in finished products. This can result in additional rework or scrap, significantly increasing production costs and time. In contrast, tool selection optimized for the job will help ensure efficient machining, reduce wear, and improve the overall quality of the workpiece. Thus, careful consideration of tool selection is essential for achieving desired results in CNC milling.
