Who is learning CNC? I just started and don't understand it. I want to know how to understand drawings and read drawing programming. Please

.

1. The drawings of the control lathe are all rotating parts. Look at your first drawing,

those belts Φ The diameter dimension of the workpiece is the x value in the program,

if we establish a coordinate system at the rotation center of the right end face of the workpiece,

then the Z value on the left side of the length dimension 6 is z-6.0,

the Z value on the leftmost end face of the workpiece is z-29.3,

the more to the right, the larger the Z value, and the larger the diameter in the X direction, the larger the x value

2. The first step is to think about the process. Only when the process is determined,

can it be programmed according to the process. The process is the soul of NC program
when you reach a certain level, you will understand that programming milling operation is very simple (except macro programs), and technology is the most important
this part needs multiple processes to be manufactured, so when you ask a programming question, you should explain your process,

that is, the program of that step will not be compiled. This step is where to locate and clamp,

what kind of blank is and what surface to process

3. When the task is handed over to you, it is a drawing? No craft? Craft is to tell you how to do each step
here are the dimensions and materials of the materials
that is to say, what should be done? In the end, it completely conforms to the figure, or Φ Don't do it or anything else,

tell me all the known conditions given to you. And how large the batch is

extended data:

NC is the abbreviation of digital control. NC technology is a method of using digital information to control mechanical motion and machining process

the early CNC system was composed of hardware circuits, which was called hard NC. After the 1970s, the hardware circuit elements were gradually replaced by special computers and called computer CNC system. Generally, special computers were used and equipped with interface circuits to realize the action control of multiple CNC equipment. Therefore, today's numerical control is generally CNC (computer numerical control), and the concept of NC is rarely used again

the feed processing route of NC lathe refers to the path that the turning tool starts to move from the tool setting point (or the fixed origin of the machine tool) until it returns to the point and ends the processing program, including the cutting path and the non cutting empty travel path such as tool cut in and cut out

the feed route of finish machining is basically carried out along the contour of its parts. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and empty stroke

NC programming is easy to learn, but you need to find the right learning and training institution. You can go to Chunhua education NC programming training to understand

1. First, clarify the intention of learning CNC machining center. This is not simple. I want to learn vertical machining center, I want to learn horizontal machining center, and I want to learn the simple policy thinking of lathe. It's what you plan to do in the future and drill in a certain direction. For example: operators, programmers, technicians, maintenance engineers, etc. have different intentions and different learning directions

2. Experiential learning is very important, because real learning still needs actual combat, but it is possible that you can only get common sense in a certain category in your current work. For example, when you are in an auto parts factory, you touch common sense related to auto parts every day, including skill requirements, processing technology and metal materials. In this category, you can make rapid progress and even become a teacher! However, you may have to learn again in another field. For example, when you change to medical devices, the skill requirements and metal materials have changed, but you have a solid foundation. Even if you change the field, you can get used to it quickly, and even surpass your current skills in combination with previous experience. Therefore, experiential learning is good, but it does not advocate that everything is common and loose. Concentration is very important

learning NC programming can lead to Chunhua education. Chunhua education group was established on July 1, 2005. The group has established more than 100 schools in Hangzhou, Ningbo, Wenzhou, Taizhou, Lishui, Jinhua, Shaoxing, Wuxi, Suzhou and other places in Zhejiang Province. How to learn NC programming

don't be in such a hurry. You will understand mechanical drawing (or mechanical drawing) naturally.

you studied CNC lathe. Your part is almost round. Processing several external threads and internal threads are ordinary triangular threads. There is also a taper. And slots And wait. Look at the drawings very clearly. It mainly depends on how your program gets this car out
