What results from deflecting of a cutting tool in machining?

• A. Improved surface finish
• B. Accurate dimensions
• C. Poor surface finish and inaccuracies
• D. Faster cutting speed

Answer: (C)

Deflection of a cutting tool during machining leads to a situation where the tool is not in the optimal position to remove material as intended. This misalignment can cause inconsistencies in the cutting process, resulting in a poor surface finish. The tool may not contact the workpiece uniformly, leading to an uneven texture on the finished part. Additionally, when the cutting tool deflects, it can alter the effective cutting dimensions. This means that the final machined part may not meet the desired specifications, leading to inaccuracies in dimensions. In contrast to improved surface finish or accurate dimensions, which are outcomes of a well-functioning machining operation, deflection tends to compromise these objectives. Higher cutting speeds may sometimes compensate for certain factors, but they do not inherently resolve the issues arising from deflection.
