The repair and maintenance of CNC machine tools are very important. Time should be taken in the work to reasonably arrange the inspection work of the machine tools to avoid damage to the work caused by the damage of the machine tools.
In the machinery industry or automation industry, CAD, CAE, and CAM complement each other. Design with CAD and then manufacture with CAM. CAD is the design process using computer technology, CAE is the use of computer simulation to analyze physical problems, and CAM is the use of computers and computer software to control machines for manufacturing, usually suitable for mass-produced parts.
Shaft parts are one typical part of machining. The shaft part is a rotating part whose length is greater than the diameter, and its surface is several outer cylindrical surfaces, conical surfaces, holes, and threads of the same axis.
