Internal turning
Insert point angle:
• Choose insert shape dependent on the entering angle
and accessibility requirements of the tool.
• In general, the largest possible point angle should
be used to maximize insert strength and reliability.
However, a large point angle needs more machining
power and has a higher tendency to vibrate due to a
large cutting edge engaged in the cut.
• A small insert point
angle can improve tool
stability as possible radial
movements give less
variation in chip area and
cutting force.
Wiper inserts
• For better surface finish and higher productivity.
• Require very stable conditions to be successful.
• Give higher cutting forces.
General recommendations when using wipers:
• Increase the feed.
• Reduce the nose radius.
