Problems solved by technology

[0002] In the sheet metal processing industry, the punching process is usually to draw parts on a 3D design platform, and manually review to determine whether the parts are machinable. After the drawings are approved, it is necessary to manually convert the 3D model into a 2D graphic, and then rely on programming software. Or manually identify two-dimensional graphic features to arrange tool programming, and finally generate CNC code programs for machine tools to call for production. figure 1 It shows the existing NC punching programming process. This method of manually reviewing the punching rationality is very easy to issue the wrongly designed drawings for production. Errors start from the design source, which seriously affects the production progress.
In addition, there is a lot of manual intervention in the entire programming process, high requirements for the skills and experience of the participants, low intelligence, and slow programming speed

Embodiment Construction

[0027] Such as figure 2 As shown, the automatic matching method of CNC punching proposed by the present invention is mainly used for punching processing of sheet metal parts, and the method includes steps 1 to 5, which will be described respectively below.

[0028] Step 1. Create punching rule library and NC punching layout rules.

[0029] The punching rule library can be embedded in the 3D design platform. The punching rule library contains the relevant design standards of CNC punching, such as combing and trimming tools, etc. written into the punching rule library, so as to realize the The punching features such as the size of the gap automatically match the trimming tool with the highest processing efficiency. Specifically, the punching rule library includes a tool rule library and a machine tool library. The machine tool library includes several CNC punching machines and the corresponding CNC punching machines. The processing rules include the programming rules of the CN...

Abstract

The invention discloses an automatic matching method and system of numerical control punching. The method comprises the steps that 1) a punching rule library, a characteristic model library and numerical control punching layout rules are created; 2) a part is drawn in a 3D design platform, and whether processing of the part is feasible is detected; 3) the punching rule library is called to generate a punching interface process; 4) a production order is received, and the numerical control punching layout rules are called to carry out suit-cut layout and generate a suit-cut punching process automatically; and 5) a specification of material is cut according to the suit-cut punching process. Thus, automatic programming of numerical control punching can be realized, manual intervention is not needed, and the production efficiency is improved effectively.

Description

technical field [0001] The invention relates to the technical field of numerical control machining, in particular to a method and system for automatic matching of numerical control punching. Background technique [0002] In the sheet metal processing industry, the punching process is usually to draw parts on a 3D design platform, and manually review to determine whether the parts are machinable. After the drawings are approved, it is necessary to manually convert the 3D model into a 2D graphic, and then rely on programming software. Or manually identify two-dimensional graphic features to arrange tool programming, and finally generate CNC code programs for machine tools to call for production. figure 1 It shows the existing NC punching programming process. This method of manually reviewing the punching rationality is very easy to issue drawings with wrong designs for production. Errors start from the design source, which seriously affects the production progress. In additio...
