Layering control method in carbon fiber machining process

Abstract

The invention provides a layering control method in a carbon fiber machining process. The layering control method in the carbon fiber machining process is characterized in that an ultrasonic machine tool is used for machining carbon fibers, and an electroplated diamond tool is adopted in a machining tool of the ultrasonic machine tool; and in the carbon fiber material machining process, reasonablemain-shaft speed value, feeding speed value, material treatment mode and an machined on a carbon fiber material, different feeding speeds are adopted for machining at different machining stages separately. According to the layering control method in the carbon fiber machining process, by adopting the electroplated diamond tool, the material removal rate during carbon fiber machining is improved,and the hole wall quality of the machined carbon fiber is improved; rotary ultrasonic machining technology is used for reducing the cutting force during carbon fiber machining and achieving a good layering control effect. A variable process machining method of the carbon fiber is proposed, the machining efficiency and machining quality are taken into account. The layering control method adopting support adding on the outlet side is adopted to effectively avoid or reduce the phenomenon of layering in machining.

Description

technical field [0001] The invention belongs to the field of carbon fiber composite material processing, and in particular relates to a layering control method in the process of carbon fiber processing. Background technique [0002] Carbon fiber composites are widely used in military, aerospace, transportation and other fields due to their excellent mechanical properties and physical properties. Hole processing is the most common processing method in the industrial application of CFRP (carbon fiber reinforced composite materials). In the process of processing, inappropriate process parameters cause delamination defects, which can easily lead to the scrapping of CFRP parts. According to statistics, in the final assembly process of aircraft, 60% of scrapped parts are caused by delamination defects. The main factor causing delamination defects is that the axial force during the drilling process is greater than the critical axial force for delamination on the material outlet si...
