The 4th National CNC Skills Competition was held in Fushan City, Guangdong Province from December 19th to 26th, 2010. Seventy-one outstanding athletes from 31 provinces and cities participated in four projects. The competition of the seven groups. The players' good spirits, exquisite operation skills, skillful processing skills and perfect processing test pieces show the high-skilled talents of contemporary CNC and leave a deep memory for people. The 4th National NC Skills Competition is the most popular NC competition in the CNC Skills Competition, with the largest number of contestants, the highest level, and the most influential event. The CNC Skills Competition demonstrates advanced technology and operational skills and is a large classroom for cultivating highly skilled personnel. The CNC Skills Competition is a platform for numerical control technology exchange. The CNC contest mobilized the potential of the contestants, demonstrating the talents of the players and promoting the rapid growth of the players. With the rapid development of equipment manufacturing technology, it is necessary to cultivate and create millions of highly skilled personnel. The CNC Skills Competition is one of the best ways. I. Review of previous NC skills contests The first phase (the first National CNC Skills Competition) is a feature of the NC competition practical test that focuses on the basic level of technology and skills. The second stage (the second national numerical control skill competition) is the characteristic of the actual test of the CNC contest: the focus of the assessment is no longer the technical skills in the processing of a single specimen, focusing on the process, focusing on the processing accuracy and precision, focusing on The overall processing process of the parts. The difficulty is much higher than the first. The third stage (the third national numerical control skill competition) is characterized by the practical test questions of the CNC competition: exploring the processing technology of complex parts, the processing technology and processing precision of the typical parts of the parts are the focus of assessment. Second, the characteristics of the fourth CNC skill contest practical test questions At this stage, the period of rapid development and transformation of numerical control technology, multi-axis processing technology and composite processing technology are the mainstream of development. The 4th CNC Skills Competition has increased the five-axis competition project of the machining center. Multi-axis machining technology is the cutting-edge technology of modern CNC machining. Multi-axis machining technology represents the main features of modern machining manufacturing technology, popularizing, promoting and improving multi-axis machining. Technology is an important task of the CNC Skills Competition. Due to the promotion of the first three CNC skill competitions, especially the implementation of the four-axis competition project set by the third CNC skill competition, the five-axis competition project for the machining center was made. Full technical preparation. The five-axis machining center manufacturer and the domestic and foreign CNC system manufacturers have given great support to the five-axis competition project of the machining center, and provided equipment for the five-axis competition. The conditions for the five-axis competition have been added. The main points of the actual operation of this year's CNC contest are: to carry forward the successful practice of the first three CNC contests, combined with the new development of technology in the actual CNC machining, highlighting the advanced, practical and operability of the test. For this reason, the actual numerical control contest of this year's CNC contest has been greatly adjusted. First of all, the game function has been strengthened, and the players are required to delve into some advanced and cutting-edge operations and programming skills in CNC machining. The test questions of this competition emphasize the structure and function of the parts. The test pieces are composed of 3~6 pieces, and the matching parts provided by the stadium form a complete part. The number of specimens processed has increased compared with previous years, and the processing difficulty and workload have been greatly improved compared with the previous session. One of the characteristics of this practical test is: the characteristics of the test piece are obvious. For example, the five-axis test piece of the machining center is assembled into a lantern shape. After connecting the power, there is a spiral propulsion and an electric "razor" action display. The engraving icon "Asian Games" reflects The atmosphere of the times. After the CNC milling test piece is assembled, it looks like a machine tool three-jaw chuck. Each set of questions has its own style and characteristics. This is a highlight of this practical test. Another feature of this practical test is: clear assessment objectives, such as the five-axis machining test for the five-axis blade test in the machining center; the four-axis cavity test for the machining center is the cylindrical and circumferential machining skills; There are 2~3 identical test pieces in the car and CNC milling test questions, which are the skills of small batch parts processing in the production process. Strengthen the mastery of automatic programming technology test sites. Mastering a variety of methods for programming and processing is the basic requirement for high-skilled talents in numerical control at this stage. In the operation test project, there are both general operation skills and the conditions provided by the game field to effectively carry out the workpiece clamping process. It also requires the machine to synchronize the program and transmit it in the automatic operation. In particular, in the competition, players are added to participate in the processing assembly test site, the purpose is to open up the players' vision, and promote the player's operational skills and comprehensive quality.
