- TITLE: INCREASING THE EFFICIENCY OF DIAMOND DRILLING OF CARBON COMPOSITES BY A DEVICE WITH COMBINED ELECTRIC MACHINES
- ABSTRACT: The paper presents an original solution to the actual problem of increasing the efficiency of the drilling of composite materials of the carbonic group through the use of coupled electric rotary type machines whose combination of movements allows to obtain controlled rotary-reciprocating motion of the instrument. Show, by creating cyclic low frequency load of the cutting zone, it is possible to improve the efficiency and quality of processing, without destroying the composite. Stress state of the cutting zone in composite materials based on carbon fibers has been evaluated and it is proved that their processing with ring diamond-coated drills is reasonable and effective. The use of a cyclic linear feeder allows significantly reducing the thickness of the destructive layer and reducing the cutting force, requiring further research on the issue of rational geometric dimensions of the tool end, the presence of cavity elements on it to remove the microstrip from the processing area. It is also proven that the proposed design of a power head with coupled electric machines to provide rotary and translatory motion in coaxial execution is a promising technical solution that can be successfully implemented in both manual tools and automated processing programmed control systems.
