Regarding whether the career of a CNC programmer is a good career, different people have different answers, and you cannot simply answer whether it is good or bad. When a person just goes out to work and faces an unfamiliar industry, in addition to considering the salary and prospects of the career, he also needs to consider his personality, abilities, interests, and hobbies. If you are engaged in a career that does not match your personality and hobbies, even if you are paid a high salary, you will be bored with the work and become listless all day long. If you think that this career is promising, but your abilities are not up to it, you will not achieve something and you will eventually fail and leave. CNC machining usually refers to computer numerical control precision machining. The main job of a CNC programmer is to compile machining programs. If you have studied CNC and have a certain foundation, such as knowing some commonly used G code and M code, and have a certain interest in this industry, then you can try to engage in this kind of work. As a CNC programmer, it is not the assembly line work. The assembly line work can start to work after simple training. As a CNC programmer, there is a certain degree of technicality. In addition to taking special training courses, it also needs specific practical experience. Of course, the salary is relatively high. As for career prospects of the CNC programmer, whatever job you have has a future, and the top pick

Advantages of five-axis machining Five-axis CNC machining is the most difficult and most widely used technology in CNC technology. It integrates computer control, high-performance servo drive, and precision machining technology, and is used for efficient, precise, and automated machining of complex curved surfaces. Compared with three-axis CNC machining, from the perspective of technology and programming, five-axis CNC machining for complex curved surfaces has the following advantages: Improve processing quality and efficiency Expand the process range Meet the new direction of composite development However, due to interference and position control of the tool in the machining space, five-axis CNC machining has a much more complicated CNC programming, CNC system, and machine tool structure than a three-axis machine tool. Therefore, it is difficult to truly realize five-axis machining, and it is even more difficult to operate and use it well. True and false five-axis machining When talking about five-axis machining, we have to talk about true and false five-axis machining. The main difference between true and false five-axis machining is whether it has the RTCP function. RTCP is the abbreviation of “Rotational Tool Center Point”. Only five-axis machining with RTCP function is true five-axis machining. Five-axis machine tools and CNC systems that do not have the RTCP function must rely on CAM programming and post-processing, and plan the tool path in advance. For the same part, if the machine tool is changed, or the tool is changed, CAM programming and post-processing must be performed again, so it can only be called false five-axis machining. In short, true five-axis machining means

3D printing seems simple, but in fact, various problems often appear in printing. For professional users or users who like DIY, it is relatively simple to solve the problems in the printing process. For ordinary users, it is especially important to be able to quickly find the questions and answers during the printing process. The following problems are all problems that may occur during the printing process, and we have given solutions. Of course, these answers are not unique. You can also use your own insights and experience to deal with common printer problems as a user. No material squeezed out at the beginning of printing If your 3D printer starts printing, the nozzle does not squeeze out the consumables, then there are four main problems: The extruder is not ready For most extruders, when the consumables are left in the high-temperature nozzle, the consumables will slowly seep out of the nozzle, which will cause a cavity to form inside the nozzle. When you print again, the consumables will gradually fill the space in the nozzle, causing a delay of several seconds. To avoid this problem, the nozzle must be filled with material and ready to be extruded before printing. The usual solution is that the extruder will draw a circle around the printed model before printing to ensure the correct extrusion of the printed material. Of course, the user can also manually control the extruder to extrude the material. The nozzle is too close to the hot bed If the nozzle is

Titanium alloy has low density, high specific strength (strength/density), good corrosion resistance, high heat resistance, good toughness, plasticity, and weldability. Titanium alloys have been widely used in many fields, such as in aerospace, automotive, medical, sporting goods, and electrolysis industries, etc. However, poor thermal conductivity, high hardness, and low modulus of elasticity have also resulted in titanium alloy becoming a metal material that is more difficult to process. This article summarizes some technological measures in the cutting of titanium alloys based on their technological characteristics. Use cemented carbide tools as much as possible. Tungsten-cobalt cemented carbide has the characteristics of high strength and good thermal conductivity and is not prone to chemical reaction with titanium at high temperatures. It is suitable for processing titanium alloys. Reasonably select the geometric parameters of the tool to process titanium alloy parts. Toreduce the cutting temperature and reduce the phenomenon of tool adhesion, we can appropriately reduce the rake angle of the tool, and increase the contact area between the chips and the rake surface to dissipate heat. At the same time, increase the clearance angle of the tool to reduce the phenomenon of tool sticking due to the frictional contact between the machined surface and the flank surface of the tool. The tip of the tool should adopt a circular arc transition to enhance the strength of the tool. When processing titanium alloys, the tools must be sharpened frequently to ensure their sharp edges and smooth chip removal. Appropriate cutting parameters. To determine the cutting parameters, please refer to

In the CNC cutting process, there are many reasons for machining errors. The error caused by the tool radial runout is one of the important factors, which directly affects the minimum shape error and the machined surface geometry accuracy. In actual cutting, the radial runout of the tool affects the machining accuracy, surface roughness, uneven wear of the tool, and the cutting process characteristics of the multi-tooth tool. The greater the radial runout of the tool, the more unstable the machining state of the tool, and the more obvious the impact. Causes of radial runout Tool manufacturing errors and clamping errors cause drift and eccentricity between the tool axis and the ideal rotation axis of the spindle, as well as specific processing techniques and tooling, which may cause radial runout of CNC milling machine tools during processing. The influence of the radial runout of the spindle itself The main reasons for the radial runout error of the main shaft are the coaxiality error of each journal of the main shaft, various errors of the bearing itself, the coaxiality error between the bearings, and the deflection of the main shaft. Their influence on the radial rotation accuracy of the spindle varies with the processing method. These factors are formed in the process of manufacturing and assembling the machine tool, and it is difficult for the operator of the machine tool to avoid their influence. The impact of the inconsistency between the tool center and the spindle rotation center When the tool is installed on
