Workshop programming system

Abstract

The invention discloses a workshop programming method. The workshop programming method comprises extracting geometrical information of a part and displaying the three-dimensional model of the part; identifying manufacturing features of the part in dependence on the three-dimensional model of the part, and generating a manufacturing feature list; planning and setting a processing technology in dependence on the manufacturing feature list of the part; and generating a numerical control program in dependence on the manufacturing features and the processing technology of the part. The invention also discloses a corresponding workshop programming module. The workshop programming method can include all information of the part from the blank to the product, and therefore the numerical control system can obtain complete product information, and intellectualization is truly achieved; automatic programming can be achieved quickly and efficiently, and the working efficiency is greatly improved.

Description

Technical field [0001] The invention belongs to the technical field of numerical control processing, and specifically relates to a workshop programming system. Background technique [0002] As the basis of the equipment manufacturing industry, CNC machine tools are widely used in aerospace, energy equipment, automobile manufacturing, shipbuilding, and 3C processing to improve processing quality and efficiency. CNC machine tools are generally equipped with a program control system. The control system can logically process the program with control codes or other symbolic instructions, decode it, express it with coded numbers, and input it into the numerical control device through an information carrier. Control the machining process of the machine tool. After arithmetic processing, the numerical control system sends out various control signals to control the action of the machine tool, and automatically process the parts according to the shape and size required by the drawing.

Problems solved by technology

[0004] In fact, the G / M code only defines the movement and switching action of the machine tool axis, and does not contain other data information of the parts to be processed, so it is impossible for the CNC system to obtain complete information about the parts, and this programming method consumes a lot of time ,low efficiency

The traditional ISO6983 standard can only complete simple linear or arc interpolation, but cannot complete very complex processing tasks, such as spline curve interpolation, which programs the center point of the tool according to the axis of the machine tool, not according to the part to be processed. Make features to program

Once the program is generated, it becomes very difficult to modify it in the workshop environment. The processing process cannot be adjusted according to the actual situation of the workshop site, and visual processing, collision detection and modification of complex CNC programs cannot be realized on the CNC machine tool.

Due to the lack of unified standards, the control commands of different CNC system manufacturers are not completely consistent, the compatibility of the entire workshop programming system is relatively poor, and NC programs cannot be reused in different CNC systems, resulting in low efficiency of workshop programming
