Method for improving multi-angle grinding experiment precision of carbon fiber composite material

Abstract

The invention discloses a method for improving the multi-angle grinding experiment precision of a carbon fiber composite material. The method comprises the following steps that: a carbon fiber composite material is machined into a plate-shaped sample with a regular polygon-shaped cross section, and the plate-shaped sample is fixed on a force measuring device of a numerical control machine tool byutilizing a positioning hole; the machining paths and machining parameters of a grinding wheel are set on the numerical control machine tool, the grinding wheel is used to sequentially complete grinding of all the machining paths along the outer contour line of the plate-shaped sample, and a force measuring device is used to record complete grinding force signals in the grinding process; and grinding force under various grinding angle changes is calculated through comprehensive analysis of the grinding force signals of all the machining paths, and the machining quality of different machined surfaces is compared and detected. The number of the regular polygons can be flexibly adjusted according to experiment subdivision requirements, the grinding force and surface quality characteristics ofmachining in all directions can be completely obtained through one-time feeding of the grinding wheel through a grinding experiment along the edges of the regular polygons, and therefore the experiment can be rapidly and accurately completed, the experiment frequency is reduced, and the experiment precision is improved.
