The detection and control system (such as the CNC system in the machine tool) that ensures the coordinated work of all parts of the machine is composed (that is, the machine is composed of the original part, the transmission part, the executive part and the measurement and control part). By further decomposing the machine, various parts can be obtained.
Strength requirement
Strength refers to the ability of parts not to break or produce plastic deformation beyond the allowable limit, which is the most basic requirement for normal operation and safe production of the machine.
The principle measures to improve the strength of parts are as follows:
① increase the size of the dangerous section of the parts and design the section shape reasonably to increase the inertia moment of the section;
② adopt high-strength materials, carry out heat treatment to improve the strength and reduce the internal stress of the materials, control the processing technology to reduce or eliminate the micro defects, etc;
