1) Select appropriate tool material with good cutting performance;
2) Select reasonable tool geometric parameters;
3) Use proper cutting liquid;
4) Select reasonable cutting amount.

16. What are the advantages of using indexable carbide blade?
A: Have the following advantages:
1) Since the blade isn’t welded and doesn’t require grinding during usage, it will avoid
internal stress and crack due to welding and grinding and improve the tool durability.
2) The tool is used for long time, and it will avoid internal stress and crack due to welding
and grinding and improve the tool durability.
3) The tool can be used for long time, therefore it will not only reduce the tool material, but
also reduce the labor and equipment required to manufacture and grind the tool.
4) If the tool is blunt, you can just rotate the blade to continue using, and thus shorten the
time in tool change, tool setting, etc.
5) It is convenient to recycle when the blade is blunt, reduce tool material consumption and
reduce the cost.
17. What is size reference?
A: The start size is the size reference.
18. How to sselect reference while drawing?
A: The design reference, process reference and measurement reference should be unified, so as to
reduce error and convenient for measurement and checking.
19. What is metal cutting process?
A: While cutting, under the impact of cutting blade and tool face, the metal being cut slipd and
becomes chips.
20. What are the influences of cutting amount on cutting force?
A: (1) When cutting depth ap and feeding amount f increase, cutting force increases; it known from
the cutting force calculation formula FZ=150apf0.75 that if the cutting depth increases by one
time, main cutting force FZ increases by one time; if the feeding amount increases by one time,
the main cutting force FZ increases by 70% (chip thickness increases and chip distortion
decreases due to the increase of feeding amount, and therefore the cutting force must be
lower).
(2) When cut plastic metal, the cutting force usually decreases along with the increase of
cutting speed; when cut brittle metal, cutting speed doesn’t have much influence on cutting
force.
21. What are the materials of tool cutter?
A: At present, the tool materials include metal and non-metal materials: metal materials include
carbon tool steel, alloy tool steel and high-speed carbide. Non-metallic materials include synthetic
diamond and cubic boron nitride ceramics, in which the hard red performance of carbon tool steel
and alloy tool steel is low (about 200 to 400°C), and are rarely used to make tools.
