G68.2-based CAM processing method for plane machining in numerical control system

Abstract

The invention discloses a G68.2-based CAM processing method for plane machining in a numerical control system. According to the method, a machining figure is input into the numerical control system inthe form of point data of line segments and arcs forming the machining figure; plane machining is carried out after G68.2-based CAM processing in the numerical control system. The method is high in flexibility and just has low requirements for an operator, and the operator just needs to have plane geometry knowledge. The method can be compatible with a 3+N multi-axis system, such as double-swing-head equipment, swing-head rotary table equipment, single-swing-head equipment and single-rotary-table equipment; rich selectivity is provided, and groove milling and edge milling can be switched andselected; and the figure of a plane can be adapted to plane machining of different angles according to the plane rotation of the G68.2.

Description

technical field [0001] The invention relates to the field of CAM processing methods of a numerical control system, in particular to a CAM processing method based on G68.2 plane processing in a numerical control system. Background technique [0002] CNC system machining centers generally run traditional G codes. Most systems only provide interfaces written online, and manual input of running instruction codes is based on artificial calculations. The processing code generated by the third-party CAM needs to be post-processed. At that time, an engineer who is specialized in the third-party CAM is required to process it, and the cost is relatively high; a few systems will also provide fixed programming modules with a few shapes, but the processing needs Ever-changing, simply can not meet the market demand. In response to the needs of the market, a few systems provide several packaged common graphics, such as chamfer, trapezoid, isosceles triangle, waist round groove, round hole...
