CAD CAM's position-based force-controlled robotic mold polishing industrial robots have made significant progress and are applied to various industrial fields. Recently, the Open Construction Industrial Robot, with its open kinematics and servo control technology, has been worked out. Using such robots, we can explore new teaching applications without the traditional complex and proficient.

For example, a 3D sanding machine is presented with a robot designed for the manufacture of exquisite furniture [1,2]. Sander's robot achieves the status of non-teaching in terms of operation and the orientation of grinding tools connected to the robot arm. In the next stage, we are trying to polish the mold of a robotic PET (polyethylene terephthalate) bottle.

In the PET bottle mold manufacturing industry, 3D CAD CAM systems and CNC machine tools are widely used and extensive, and these advanced systems have greatly rationalized the design and manufacturing process of metal molds. However, the CNC machining and polishing process of post-PET bottle molds has been difficult to automate. Therefore, we must have the ability to depend on the skilled workers who control both dexterity and skilled abrasive trajectory control, as shown in Fig.

1。Skilled workers are commonly used to install abrasives of various sizes and shapes. When using these types of tools, keep in touch.

Metal workpieces with the required contact force and tangential velocity are the most important factors in obtaining a high-quality surface. When performing the task of polishing, it is also a critical point that skilled workers along the surface of the object with abrasives come reciprocatingly the word I have not seen.

I didn't see a supplement just now.,I thought you were going to ask a question.。

Last month we asked students about their free activities. Our questions were about exercise, computer use, and watching TV, and here are the findings.

We found that only 15% of students consistently exercised every day. 45% of students exercise four to six times a week. 20% of students exercise only once or three times a week. A further 20% of students don't exercise at all.

It's no secret that many students are online all the time, but to our surprise, 90% of them go online every day. The remaining 10% of students play at least three to four times a week. Most students use computers for entertainment rather than study.

The answer to our question about watching TV is also quite interesting. Only 2% of students watch TV once or three times a week, 30% watch TV four to six times a week, and 85% watch TV every day. Although many students enjoy watching sports shows, game shows are still the most popular.
