Method for machining slotted holes on carbon fiber laminated boards

Abstract

The invention discloses a method for machining slotted holes on carbon fiber laminated boards, which belongs to a machining method for nonmetallic materials, solves the problem that by the existing milling and drilling methods, carbon fiber laminated boards are easy to laminate, split and burn, and aims at improving the machining precision of carbon fiber composite products and reducing the surface roughness of carbon fiber composite products. The method disclosed by the invention comprises a clamping step, a machining step and a post-processing step, wherein the machining step is one or two of a milling machining step and a drilling machining step. According to the invention, in the machining process, a non-deformed clamping mode is used, and through selecting reasonable cutting tool materials, geometric parameters of cutting tools, and milling and drilling machining parameters, the appearance allowances in machining are reasonably arranged, thereby solving the quality problems of laminating, splitting and burning and the like existing in the process of opening or drilling carbon fiber thin-wall revolution bodies and carbon fiber laminated boards by using the traditional methods, so that the qualified rate of carbon fiber parts is increased from 50% to more than 99%.

Description

technical field

[0001] The invention belongs to a machining method for non-metallic materials, in particular to a method for machining slot holes on a carbon fiber laminate. Background technique

[0002] Carbon fiber composite material is a non-metallic material with excellent mechanical properties. It has the characteristics of light weight, high strength, easy molding, and corrosion resistance. It has been widely used in many fields such as military and civilian. Carbon fiber composite structural parts are the same as metal material structural parts. After the blank is formed, it generally needs further machining of the inner shape, and the connection between carbon fiber composite parts and between carbon fiber composite parts and metal parts requires holes and openings. . Due to the high overall strength and high brittleness of carbon fiber composite materials, factors such as cutting force, vibration, and clamping during machining may cause open mechanical damage to th...
