1. Factors affecting the selection of CNC cutting tools

When selecting the type and specifications of cutting tools, the main factors to consider are:

(1) Production nature

The production nature here refers to the batch size of the parts, mainly considering the impact on tool selection from the perspective of processing costs.

For example, using special cutting tools in mass production may be cost-effective, while choosing standard cutting tools is more suitable for single piece or small batch production.

(2) Machine tool type

The influence of the CNC machine tool used to complete this process on the selected tool type (drill, turning tool, or milling cutter). Under the condition of ensuring good rigidity of the workpiece system and tool system, it is allowed to use high productivity tools, such as high-speed cutting turning tools and high feed rate turning tools.

(3) CNC machining plan

Different CNC machining schemes can use different types of cutting tools. For example, the processing of holes can be carried out using drills and reamers, as well as drills and boring cutters.

(4) The size and shape of the workpiece

The size and shape of the workpiece also affect the selection of tool types and specifications, such as using special tools to process special surfaces.

(5) Surface roughness of machining

The surface roughness of the machining affects the structural shape and cutting amount of the cutting tool. For example, when rough milling of the blank, a coarse tooth milling cutter can be used, and when precision milling, a fine tooth milling cutter can be used.

(6) Processing accuracy

The machining accuracy affects the type and structural shape of precision machining tools, such as the final machining of holes, which can be processed using drills, reamers, or boring cutters based on the accuracy of the holes.

(7) Workpiece material

The material of the workpiece will determine the selection of the tool material and the geometric parameters of the cutting part. The tool material is related to the machining accuracy and material hardness of the workpiece.
