With the wide application of CNC machine tools in production practice, CNC program design has become one of the key issues in CNC machining. In the process of programming the NC program, it is necessary to select the tool in real time and determine the amount of cutting in the human-computer interaction state. Therefore, the programmer must be familiar with the selection method of the tool and the principle of determining the amount of cutting, so as to ensure the processing quality and processing efficiency of the part, give full play to the advantages of the CNC machine tool, and improve the economic efficiency and production level of the enterprise.
CNC machining tools should generally include general-purpose tools, universal joint shanks and a small number of special shanks. The tool holder is connected to the tool and mounted on the power head of the machine, so it has been standardized and serialized. There are several ways to classify CNC tools.
First, according to the tool structure can be divided into:
1. monolithic;
2. Mosaic,
3. It adopts welding or machine clamp type connection, and the machine clamp type can be divided into two types: non-indexing and indexable ;
4. Special types, such as composite tools, shock-absorbing tools, etc.
Second, according to the materials used in the manufacture of tools can be divided into:
1. High speed steel cutter ;
2. Carbide tools ;
3. Diamond tool ;
4. Other material tools, such as cubic boron nitride tools, ceramic tools, etc.
Third, according to the cutting process can be divided into:
1. Turning tools, divided into outer circle, inner hole, thread, cutting tool, etc .;
2. Drilling tools, including drill bits, reamers, taps, etc .;
3. Cutting tools ;
4. Milling tools, etc.
