Question 156General Subjects - QMED

The correct answer is C) chatter. If the distances "A" and/or "B" as shown in the illustration are excessively increased, the tool will be more susceptible to chatter. Chatter is an undesirable vibration that can occur in machining operations, which can negatively affect the surface finish and dimensional accuracy of the workpiece. Increasing the distances "A" and/or "B" reduces the tool's rigidity, making it more prone to vibration and chatter during the cutting process. The other answer choices are incorrect because they do not accurately describe the effect of excessively increasing the tool's distances "A" and/or "B".
