What kind of can be regarded as a true CNC programming master?
To become a good programmer must have five hearts: humility, carefulness, patience, responsibility, gratitude. Do not explain that we all understand that with these five hearts, many things will be done, but can it not really become a programming guru? Many people asked, does the programming master need 10 years of experience? If not, what kind of real programming master can it be? Today, I will talk about personal views on this issue. By the way, I will also sum up some years of programming and teaching experience.
The first thing to understand is that the length of time a person works in an industry does not equal his personal level. Because there are many people who work hard to get to work, or if they are working in a mechanical way, they do it for 10 years and 8 years. The result will be the same thing as before. On the other hand, if it is done at the level of intention, it will be more than a person with 10 years and 8 years of experience.
What kind of can be considered a real programming master?
The highest realm of programming masters is: to complete the most satisfied customers with the most simple tool path and the fastest processing speed.
The simplicity is simple and tasteful. This quality is embodied in the grasp of programming details. Every small part must be carefully considered. The knife path is concise and practical, and it does not require more fancy, starting with the actual situation. Such as taking into account the aircraft operator's work, mold structure, clamping, EDM, direction, saving mode die, then Shun, tool costs and so on.
The fastest processing speed is not as fast as a few programs. In some cases, it takes less time to write more than one tool and combine them to complete a certain local processing; you need to consider before and after using a knife. There is a clear understanding of the characteristics of each processing method; for example, using a contour method to open the rough, it is necessary to lift the knife less, get up faster, there are reference line knife path and so on.
What the customer is most satisfied with is that the brighter or more polished your workpiece is. This is a misunderstanding of many people. They blindly pursue the perfection of the knife path, the workpiece is bright, regardless of time, do not understand the structure of the mold, do not understand the purpose of the workpiece, every place is clear, each place can not be processed with copper Normally sparks, each surface has R knife light, and all of them have very small tolerances, small steps, and take a lot of time. The most typical example is where the blow molds dodge the air and do not know where they are rushing. The result is that the place is beautiful, but it takes a long time. The customers are not happy because the places are useless and you delay. Time, did not deliver to him as soon as possible, delayed the mold cycle. There are a lot of mold people who are going to dry the grain. What they want is the feeling of sanding. You can finish the same process again. Therefore, the customer is most satisfied with the completion of his work as quickly as possible to meet his requirements.
Next, I used the programming software Powermill as an example to summarize some practical things.
1. Preparation
Before opening thick, there is an important thing to do well, that is, the model is positioned, whether it is in the middle or in the opposite side, whether it is the top zero or the bottom bottom number, whether the long direction is the x direction or something else. These must be first Make it clear that if you do it better, then it's no use wondering if you're going to do it better. Of course, there's nothing wrong with the materials that you're going to process. Many programming and operating systems counteract both the front and back boxes, and they also have the wrong data. If you want to do this well, you usually communicate with your superiors much more often. Don't be too busy with the situation. You must reflect more and communicate with the operating mechanism. Express your meaning clearly to him. Don't misunderstand it. What do you mean, you'd better mark with a marker pen, which piece of material, what direction, how to position and take the number. There are mold structure these many humbly consult the workers in the mold room, free to go online to see some of the information.
2. Open rough
Opening is usually the first tool path, and the processing time is also longer, so it is very important to make it. The most commonly used roughing strategy is the removal of the model area. One thing to note is:
1) The choice of tools, which should be emphasized in particular, is also something that many people do not care about, that is, in the same time can complete the work, consider the cost of the tool. In this way, you are creating more value for the company or private owner, and virtually increasing your own value.
2) The margin, if too much, the next one is heavy, too little may be too much. In particular, the amount of flying knife should pay attention to, such as the remaining side of the D30R5 left 0.5mm can stay at the bottom of 0.2mm.
3) Cut-in and cut-out, cut-out can be set to none, cut-in is set to two, the first choice can be set to a horizontal arc, the second choice is set to oblique.
4) Anti-stepping knife, this is done by setting the threshold value.
5) Anti-crater knife, this is done by rounding the knife path, generally set to 0.1 or more.
6) Open rough, especially if there is open on the edge, when not open, it is necessary to adjust the rough size, and sometimes in order to improve the efficiency of open rough, you can even draw borders and make border blanks. In addition to the clearing of the model area, roughing may be used in some cases, such as contours, reference line processing, contour section removal (use a lot more when falling surfaces), two-dimensional curve area elimination (less use), and parallel finishing (falling surfaces). When used) and so on. Whether the use of a knife path is not a death rule is in which direction. As long as you can meet your requirements and it is safe and fast, you can use it flexibly. This is what I call the programming student "pragmatic work-around."
3. Two coarse or medium light
Usually use the contour to go on the whole, the light with two rough one-time to get, such as the D17R0.8 knife. Which should pay attention to:
1) Anti-squeeze knife, which is achieved by additional blanks;
2) Anti-stepping knife is accomplished by deleting the knife path.
