Study of machinability and processing of synthetic materials

Cutting parameters should be adjusted with regard to the material being processed, among other factors. Precision, speed, and efficiency are also taken into account. Modern tools can provide all this, provided that they are used for a specific purpose and set up correctly. When selecting cutting parameters, attention should be paid to the hardness of the material, which is the resistance it offers when a cutting tool is pressed into it, as well as the way deformations occur.

The selection of cutting parameters involves:

• Choosing the appropriate tool;

• Selecting the right cutting insert for the material, considering its coating;

• Determining the basic cutting parameters (Vc – cutting speed and Fn - feed rate) recommended by the manufacturer for processing the specific material;

• Based on the selected cutting parameters, determining the machining parameters for the machine tool (spindle speed n and feed rate vf), taking into account the maximum parameters of the selected machine;

Research plans for cutting trials have been outlined for the following machining processes: turning, milling, drilling, waterjet cutting, and knife cutting.
