Hardware introduction CNC machining center programming production process

Programming production process:

When programming, you should follow the programmed production process, otherwise it is easy to appear incorrect. First, you must analyze the engineering drawings, write the processing technology sheet, etc., then you must write the processing program of the product workpiece, and then type the program into the CNC machine tool, and finally carry out the program inspection and cutting test.

1) Analyze engineering drawings

When processing abrasive tools on a CNC machine tool, the initial material obtained by the programming staff is a part drawing. According to the part drawing, it is possible to analyze the appearance of the part, the precision of the specification, the roughness, the raw material of the product, the type of the blank and the quenching and tempering treatment, and then select the CNC lathe and the cutting tool, clarify the precise positioning of the clamping equipment, the processing method, The processing sequence and the size of the tool durable.

In the whole process of clarifying the processing technology, the characteristics of commonly used CNC machine tools should be taken into consideration, and its functions should be fully utilized to ensure effective processing lines, low feed frequency and short processing comprehensive working hours. In addition, relevant production process documents should be filled in, such as CNC machine tool processing process credit card, CNC machine tool tool credit card, and tool route map.

(2) Writing program

The programming staff should select effective machining methods and main drilling parameters based on the analysis results of the machining process and the characteristics of the programming mobile phone software, and write highly efficient programs. For example, to use UG mobile phone software to carry out programming, you must understand the various programming methods of UG and the actual meaning of various main parameters.

(3) Type in the program

The methods to enter the processing program into the CNC machine tool include: optical reader, computer keyboard, hard disk, audio tape, memory card, RS232 interface and Internet, etc. At this stage, the common methods are: according to the numeric keyboard program; according to the communication socket between the electronic computer and the CNC machine tool, the processing program is transferred to the program memory of the CNC machine tool (now some new CNC machine tools have long been equipped with large-capacity memory cards to store the processing program. It is a numerical control machine tool program memory application, so the numerical control machine tool program can be stored in the memory card in advance); it can also be processed by the electronic computer to the CNC lathe while processing (this kind of method is generally called DNC, and the program is not stored in CNC lathe storage).

(4) Testing procedures and conducting trial cuts

The CNC machine tool program must undergo testing and trial cutting before it can be declared processing. Generally, it is possible to use the analog simulation control module of the numerical control software, and the first to carry out the simulation simulation processing on the electronic computer to distinguish whether there is a collision, less cutting, and more cutting. Graphical simulation simulation processing can also be carried out on the numerical control machine tool with graphic simulation function to check the accuracy of the tool trajectory. If you want to learn and train UG programming, you can add QQ group 304214709 to receive learning materials and course content. For non-existent CNC machine tools, dry operation detection can be carried out. However, this type of method only detects whether the tool path is appropriate, and cannot detect the tool and tool setting deviation. Since there will be machining deviations caused by poor tool adjustment or some data errors, the key process of first sample cutting must be carried out. When it is found that there is a processing deviation that does not meet the requirements of the engineering drawing, the reason should be analyzed to facilitate the modification of the processing procedure or the use of tool specifications compensation and other countermeasures until the product workpiece that meets the requirements of the engineering drawing is processed.
