Abstract

The invention provides an experimental device for cutting off a carbon fiber composite material, and belongs to the field of research on hardly machined material cutting devices. The experimental device is provided with experiment functional devices by taking a cutting device as a basic structure, wherein the experiment functional devices comprise a work piece quick assembling-clamping and temperature control device, a high-speed micro-examination device, a temperature and cutting force online measuring device and a dust remover. In the high-speed micro-examination device, a lens is connected with a high-speed camera, the high-speed camera is arranged on a single-axis precision displacement platform pedestal which is arranged on a camera support, a light source is aligned to a cutting area and the high-speed camera is connected with a computer system. The experimental device for cutting off the carbon fiber composite material, which is disclosed by the invention, can effectively realize the observation on a cutting process, precisely measures the temperature and the cutting force in real time, controls the temperatures of a sample and a cutter, and studies on material breakage forms, material removal mechanisms and cutter abrasion mechanisms under different cutting conditions, so as to provide experimental support for the explanation of the carbon fiber composite material cutting basic theory.

Description

technical field [0001] The invention belongs to the research field of cutting devices for difficult-to-machine materials, and relates to an experimental device for cutting carbon fiber composite materials. Background technique [0002] Carbon fiber composite materials (CFRP) have the characteristics of high specific strength, high specific stiffness, fatigue resistance, etc., can effectively reduce the weight of aircraft structures, and have been widely used in the aerospace field. An important guarantee for sex and environmental protection. With the extensive application of carbon fiber composite materials in large-scale aerospace main load-bearing components, based on the requirements of high service reliability in the complex load-bearing environment of large-scale main load-bearing components, the quality requirements for its machining are also more stringent. In aircraft components, a large amount of machining is used to ensure dimensional accuracy and connection assem...
