SINNGLE POINT CUTTING TOOL

What is the primary function of a positive rake angle in a cutting tool?

• Increase cutting forces

• Facilitate easier chip removal

• Strengthen the cutting edge

• Decrease tool wear

How does a negative rake angle affect the cutting edge of a tool?

• Makes it sharper

• Increases cutting edge strength

• Decreases heat generation

• Increases chip flow

Which rake angle is most likely to be used for machining hard materials?

• Positive rake angle

• Negative rake angle

• Neutral rake angle

• Zero rake angle

Why is chip control important in machining?

• To increase tool life

• To ensure smooth operation and prevent tool damage

• To reduce cutting forces

• To increase cutting speed

What impact does a positive rake angle have on cutting forces?

• Increases cutting forces

• Reduces cutting forces

• Has no effect on cutting forces

• Doubles the cutting forces

What is one consequence of using an excessively positive rake angle?

• Reduced tool wear

• Increased tool strength

• Decreased chip removal

• Increased likelihood of tool chipping

Which rake angle provides a balance between cutting forces and tool strength?

• Positive rake angle

• Negative rake angle

• Neutral rake angle

• Zero rake angle

How does a neutral rake angle benefit machining processes?

• It maximizes tool strength

• It provides a balanced approach for cutting various materials

• It minimizes heat generation
