ABSTRACT:
This is a method for working and processing different materials, mainly elastomers, in different manufacturing processes. Moving cutting tools act upon the material to create ultrasonic-frequency oscillations of the material in a working zone. The power of the drive units is set at no less than 100–300 kW. The revolution speed of the tool is set in the range of 3,000–12,000 rev/min. The quantity of cutting edges for the tool is selected according to the relation ω×n is less than 800, where ω is equal to the angular velocity of the tool and n is equal to the number of cutting edges of tool. The attach angles of the tool are set in the range of 85–95 degrees. Separate particles of material embedded to the cutting portion of the tool are removed using a fluid flow containing gas and/or liquid. The effect is an enhanced efficiency of method, increased disposition degree and uniformity of ready product structures.
