Using the VNUC simulation system of Fick's CNC machining simulation software, multimedia teaching methods are used to teach machine selection, blank clamping, tool selection, workpiece coordinate system determination, processing program import, automatic processing, etc. They have a basic understanding of the commonly used CNC system tools such as FANUC system, SIEMENS system, Huazhong system, etc., through the teacher's teaching and using the school's CNC machine tools to enable them to independently operate the machine tools and improve their practical ability.
For students with comprehensive ability, teachers can help them choose topics, use different instructions to program, make the topic one more solution, stimulate their interest in learning, and exert their potential to enhance their innovative ability. For students whose basic knowledge is not well mastered, teachers should select some topics with strong basic knowledge according to their characteristics, strengthen their mastery of basic knowledge, and enable them to master both basic knowledge and enhancement in numerical control training courses. The hands-on ability has improved their practical ability and enhanced their confidence in the future.
According to the teaching plan, the homework assignments are arranged to enhance students' self-learning ability and strengthen the teaching effect of the numerical control training course. After each training session, students will be assigned the training content of the next class, so that students can purposefully learn the contents of the next training session. In the class, students are asked to answer a few questions, understand the self-study effect of the students, and focus on explaining the content that is easily confused and inaccurate. This not only improves the students' self-learning ability, but also improves the students' ability to analyze and solve problems, and enhance the effect of numerical control training.
According to the test equipment and the ability of students to group, organize competitions to improve students' comprehensive quality and practical ability. Students are divided into groups according to the school's existing equipment. The ability level of each group is high, medium, and low. Students with such high levels can drive students with low levels. Introducing a competitive mechanism through organizing competitions will help mobilize students' enthusiasm for learning the course and the initiative to acquire knowledge, enhance students' team awareness, improve students' ability to analyze and solve problems, and enhance students' practical ability. And comprehensive quality.
Use modern technology to strengthen the cultivation of students' innovative ability and practical ability. The development of modern science and technology provides a broader knowledge base, equipment foundation and relaxed teaching environment for the cultivation of innovative education and practical ability. The CAXA 3D solid design software enriches the teaching content of the classroom, and activates the learning atmosphere. Students are allowed to use computer-aided design software to draw the entities, and then generate G code through post-processing to simulate the machining of parts.
This teaching method makes the parts intuitive and visual, and the processing process is clear. The students' impressions are rich and vivid, and the learning atmosphere is active. It not only consolidates the content of the CAXA design software course, but also the actual operation of the machine tool. The foundation has been laid, which has increased the charm of practical training courses, allowing students to think actively, increase the knowledge content, expand the scope of vision, and lay a solid foundation for the cultivation of innovative and practical abilities.
Reform the assessment of practical training courses, improve students' innovative ability and practical ability, adopt a diversified evaluation method, and focus on assessing students' innovative ability and practical ability. The results of organizing the competition in teaching are part of the student's usual grades. In the course of training, students who have a multi-solution, innovative ability and strong hands-on ability will score extra points, avoiding an examination to determine the final score, so that students can learn and acquire knowledge in a proactive manner during the training process. Expand innovative thinking and improve practical ability. The test scored high with innovative thinking, skilled machine operation, short processing time, and good product processing quality. The usual grades and test scores each account for 50%, which is finally determined as the test score for this course.
In short, it is necessary to reform the effect of CNC machining training courses, improve students' innovative ability and practical ability, proceed from the actual situation of students, respect the objective quality of students, stimulate students' enthusiasm for learning, and continuously enhance their innovative ability to make students Chile. Both non-intellectual factors have been exerted so that they can participate voluntarily and proactively in the entire teaching activities. Let me learn to learn for me, using advanced science and technology to let students understand the latest CNC in the world today. The development of technology, strive to improve the teaching effect, and cultivate a large number of talents with innovative consciousness and practical ability for the society.
