How does an increased lead angle affect chip formation? Increased lead angles create:POSSIBLE ANSWERS:Chips that are wider and thinner, allowing for faster cutting speeds.Chips that are hard and tough and cause rapid flank wearing.Discontinuous chips, leading to improved surface finish quality.Thick chips that tend to crater the tool and tangle the workpiece.

An increased lead angle in machining affects chip formation in the following ways:

1. Chips that are wider and thinner: An increased lead angle causes the chips to be wider and thinner. This is because the lead angle determines the direction of the chip flow. A larger lead angle causes the chips to flow in a more sideways direction, which results in wider and thinner chips. This can allow for faster cutting speeds as the chips are easier to remove.

2. Does not cause chips that are hard and tough: The hardness and toughness of the chips are more related to the material being cut and the cutting conditions, not the lead angle. Therefore, an increased lead angle does not necessarily cause chips that are hard and tough and cause rapid flank wearing.

3. Discontinuous chips, leading to improved surface finish quality: An increased lead angle can lead to the formation of discontinuous chips. This is because a larger lead angle can cause the chip to break up more easily. Discontinuous chips can lead to an improved surface finish quality as they are easier to remove and less likely to scratch the workpiece.

4. Does not create thick chips that tend to crater the tool and tangle the workpiece: An increased lead angle actually creates thinner chips, not thicker ones. Therefore, it does not lead to the formation of thick chips that tend to crater the tool and tangle the workpiece.
