What is typically the result of using too high a chip load in milling?

  1. Decreased accuracy and finish

  2. Enhanced cutting efficiency

  3. Extended tool life

  4. Increased coolant usage

The correct answer is: Decreased accuracy and finish

Using too high a chip load in milling typically results in decreased accuracy and finish. Chip load refers to the amount of material that a cutting tool removes during each rotation. When this load is too high, the cutting tool may become overloaded, leading to excessive wear or potential failure. This excessive loading can cause vibrations, leading to instability in the milling process. Such vibrations can result in poor surface finish and dimensional inaccuracies, as the cutting tool might bounce or chatter, failing to maintain a consistent cutting path. These conditions deteriorate the overall quality of the machined part. In contrast, a balanced chip load allows for efficient cutting while maintaining the integrity of both the tool and the workpiece, promoting a good surface finish and accuracy.
