Abstract

The invention discloses a processing path generation method of a machine tool. The method comprises the following steps: 1, according to geometric shape and technical parameters of a processing part, generating a machine tool processing program; 2, according to the machine tool processing program, adjusting a knife site position and a cutter shaft vector of the machine tool, setting a key control point, adjusting a direction and a cutting depth, and determining a workpiece clamp and a workpiece height; 3, performing acceleration and deceleration planning and smooth switching processing on a processing segment in a processing path of a cutter by use of a five-segment S-curve method; 4, determining cyclic processing frequency; 5, performing compensation processing on a corner according to a radius of the cutter; and 6, fitting the machine tool processing program to perform grinding wheel grinding processing on the processing part. According to the invention, the machine tool processing path is continuous, the cutter can be prevented from turning idly, the processing method is simple, the processing efficiency is high, the processing precision is high, the production cost is low, and therefore, the application prospect is quite large.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a method for generating a processing path of a machine tool. Background technique [0002] Machine tool processing refers to the processing of raw materials with machine tools. The cutting process of the machine tool is realized by the relative motion between the tool and the workpiece, and its motion can be divided into surface forming motion and auxiliary motion. The surface forming motion is the motion to obtain the required surface shape and size of the workpiece, which includes main motion, feed motion and cutting motion. The main motion is the motion that plays a major role in stripping excess material from the workpiece blank. It can be a rotary motion of the workpiece (such as turning), a linear motion (such as planing on a planer), or a rotary motion of the tool (such as Milling and drilling) or linear motion (such as slotting and broaching); feed motion is the mov...
