Introduction of WC-based (WC-Co)
In 1923, cemented carbide was patented in the United Kingdom and the United States.
They begin to be used to make blades of various knives [1].
Different tool wear tests show that the cutting edge made of WC is more wear-resistant, while it is higher than the blade made of stellite
High speed steel
Alloy or Alloy Tool Steel [2].
The average hardness of the diamond cutting edge is four times that of the WC cutting edge, but it is four times weaker in the case of bending strength, in addition, it is characterized by low toughness [3].
Carbide is an alloy of various metallic carbide. -tungsten (W), titanium (Ti)
And/or vanadium (V)
Adhesive with elastic adhesive.
WC was first used in wood processing industry in 1929 [3].
Usually the hard metal used in the wood industry is made of 80-90% W and 20 -10% cobalt (Co)[3].
The cutting edge of the tool used in composite wood processing contains about. 2. 5 -
4% Co, is the most wear-resistant.
These tools are recommended for the treatment of wood materials with a uniform structure, which leads to wear [4].
When the wood composite is processed, the cutting edge of the tool is more intensive than the cutting edge of the processing solid wood [1-4].
When the tool is used to handle wet wood or wood material, more intensive wear occurs on the cutting edge of the tool [3,4].
During cutting, thermal, electrical and chemical factors affect the wear and tear of WC tool blades [5-11].
Wear and tear of the knife (
Micro changes-
Geometry of cutting edge)
Is the main factor restricting the efficiency of tools [4, 6, 12].
According to the test, the wear of the cutting edge of the tool depends on the length of the processing or the duration of the processing, the tool material, the cutting method and the main properties of the processing of solid wood or wood composite [3, 4, 13, 14].
The wear of the cutting edge of the tool can be divided into three stages: initial, monotonous and emergency [5,6, 13].
Wear of the cutting edge leads to a continuous decrease in the quality of the machined surface [15-17].
Due to the particularity of machining, the surface is uneven.
The size of the uniformity depends on the machining mode, the micro-geometry of the cutting edge of the cutter blade (nose)
Cutting direction and cutting feeding speed [18-20].
The main purpose of this study is to determine the effect of the milling mode on the tool wear and surface quality of the processed router. 2.
