What is a common cause of long, unbroken snarls winding around the tool or workpieces in turning operations?

• High feed rate

• Low feed rate

• Correct tool geometry

• High cutting speed

Which solution is recommended for chip control when the feed is too low for the chosen geometry?

• Decrease the feed

• Use a tool with lower precision coolant

• Increase feed

• Change the material

What is advised to do when the depth of cut is too shallow for the chosen geometry to control chip formation?

• Increase the depth of cut or select a geometry with better chip breaking capability

• Use a smaller nose radius

• Reduce the feed rate

• Use a tool with less entering angle

For controlling very short chips that stick together, what type of geometry should be chosen?

• A geometry designed for lower feeds

• A geometry with poor chip control

• A geometry designed for higher feeds, preferably a single-sided insert

• Any type of geometry

What is a suitable solution when facing bad chip breaking due to high feed rate for the chosen geometry?

• Increase the feed rate further

• Choose a geometry designed for lower feeds

• Reduce feed

• Use a tool with smaller nose radius

What is a common cause of a "hairy" surface finish on a component?

• Incorrect tool geometry

• Excessive notch wear on the cutting edge

• Low feed rate

• Use of non-coated inserts

Which solution is recommended for chips breaking against the component and marking the finished surface?

• Increase the feed rate

• Select a geometry that guides the chips away from the component

• Use a smaller nose radius

• Increase the depth of cut

What is advised to prevent burr formation at the start or end of a cut?

• Use a holder with a large entering angle

• Increase the cutting speed

• Use a holder with a small entering angle

• Use a larger nose radius

For reducing the rough surface generated by a high feed rate and small nose radius, what is a recommended solution?

• Select a wiper insert or a larger nose radius

• Decrease the cutting speed

• Use non-coated inserts

• Increase the depth of cut

What is a typical cause of high radial cutting forces during internal machining with boring bars?

• Suitable entering angle

• Unsuitable entering angle

• Correct tool positioning

• Adequate clamping rigidity
