CNC cutting machine programming is no longer a problem

The CNC cutting machine is used as an automatic cutting and cutting equipment. Its working principle is: converting the graphic to be cut into a machining program (G code) through programming software, and then driving the numerical control system through the machining program to control the CNC cutting machine to perform the cutting work.
In terms of cutting form, CNC cutting machine is divided into CNC flame cutting machine, CNC plasma cutting machine, CNC water cutting machine (waterjet), laser cutting machine and so on. In principle, the programming principle is the same regardless of the cutting method. Therefore, in principle, programming software for CNC plasma cutting is also suitable for water cutting or laser cutting.
The G code instruction set used by the CNC system of different manufacturers is different. However, a general-purpose CNC cutting programming software can customize the cutting G code instruction set. Therefore, there is basically no condition that cannot be used.
From the function of CNC cutting programming software, it can be divided into two types: general-purpose programming software and professional CNC cutting programming software.
The function of the general-purpose programming software is to select the part to be cut drawn by the drawing software (such as: AutoCAD) according to the numerical control cutting process, and finally convert it into the numerical control processing G code instruction. There are many such software, such as: FastCAM, IBE, StarCAM, SmartNest and so on. Each CNC cutting programming software differs depending on the version, and the cutting process it supports varies.
Professional CNC cutting programming software is a CNC cutting programming software that is introduced for a specific industry. Such as: Wentai software for the advertising industry, PM2000 for cutting galvanized ducts, etc. This kind of software is specially designed for a certain industry to carry out special optimization and function expansion, which can realize a set of software internal parts design, material discharge, cutting and processing program output integration operation.  


CNC cutting machine programming common problems and solutions
First, the programming software can not open or opened too slowly.
The software is used for too long, and the program spawns too many junk files and should be cleaned or reinstalled.
There is a system failure or too many files on the desktop.
Second, the output of the program pattern found certain color lines (will seriously affect cleavage, destruction of the workpiece) ----- garbled software outputs, to find the corresponding code into the program codes manually remove or modify the pattern. If you cannot modify it, you can rewrite the output.

Third, the program could not be read.
The program is named incorrectly and cannot be Chinese characters when naming.
Two " . " numbers cannot appear in the program name .
The program name is too long.
Poor U disk contact.
     Fourth, NC plasma cutting machine interface resolution.
Fifth, we must pay attention to the size of the plate while programming, to have unilateral 10mm cutting margin.
    
Arc voltage; plasma system fixed output current 200A , adjust the arc voltage to adjust the output plasma energy, the greater the arc voltage, the greater the output energy.
     Arc height; that is, arc height, because the plasma arc is a football shape, the arc height seriously affects the cutting quality. If improperly selected, the cutting surface will not be vertical or severely deviated. Generally, the arc height of the thick plate is smaller than the thin plate. .
Delay; mainly used for perforation, the purpose of delay is to be able to perforate normally, is the time required from the perforation to travel when cutting, and the delay time of the thick plate is greater than that of the thin plate.
Movement speed; reasonable parameters have only one optimal movement speed.
     Hand (self) height adjustment system; here is mainly set up the automatic height adjustment system, the main adjustment in the automatic height adjustment system is the perforation height, the perforation height is set to protect the torch during piercing, the unreasonable perforation height is easy to damage Consumables can even cause serious consequences of burnout (too high to burn the electrode, too low to easily burn the gun).
    

Generally, the hand-held cutting machine will be replaced by the CNC cutting machine slowly. The main reason is that the difference between the CNC cutting machine and the general hand-held cutting device lies mainly in the automatic operation of its numerical control system. Learning to understand the programming mode of the numerical control operating system is bound to play an effective role in the operation of the CNC cutting equipment. Below we will explain the programming method and working principle of the numerical control operating system.
From the working principle, the CNC cutting machine needs an instruction before the work to command it to walk. This instruction is called CNC cutting program. How does this program come from?

1. Automatic programming: Using a computer or a programming machine to complete the process of programming a part program is convenient for complex parts.
　 2. Manual programming: The specific shape and size are obtained from the part drawing. The part is graphically analyzed, processed, numerically calculated, and then the program list is input into the cutting machine system in the form of a button. The system will execute according to the input program. Finally get the graphics you need.
　 3. Active programming: Using the CNC cutting machine computer or the knitting machine to complete the process of compiling the part program, it is very convenient for complex parts.

4. CAD : Using CAD software to cooperate with the cutting machine application software developed by our company, only need to input the required size and graphics into CAD , generate the cutting machine graphics, do the compilation process, and then generate the cutting machine code, directly convert to CNC cutting. Cut on the machine. Although this programming has a single effect, it is easy to learn and low in price, and it is still the choice of SMEs.
