Microcomputer system is the "brain" of the whole system, intelligent control and management of the whole system, and processing of detection signals, generally using single-chip computer system. For example, the infusion pump adopts a highly integrated 32-bit ARMCPU system to fully control the infusion process, and adopts dual CPU to ensure the safety of the system.

CNC machining has the following advantages:

The micrometer often used in work, the scientific name should be called the spiral micrometer, it is made according to the principle of spiral enlargement, that is, the screw is rotated in the nut for one revolution, and the screw will move forward or backward along the axis of rotation for a distance of one pitch.

At the beginning of CNC machine tools, aircraft parts with complex surface are selected as machining objects, which is difficult to be solved by common machining methods. The biggest characteristic of NUMERICAL control machining is to use perforated tape (or tape) control machine tool for automatic processing. Because aircraft, rocket and engine parts have different characteristics: aircraft and rocket zero, component size, complex surface; Engine zero, small component size, high precision. Therefore, aircraft, rocket manufacturing department and engine manufacturing department of the choice of NUMERICAL control machine tools are different. In the aircraft and rocket manufacturing to use continuous control of large CNC milling machine, and in the engine manufacturing both use continuous control of CNC machine tools, also use point control of CNC machine tools (such as CNC drilling machine, CNC boring machine, machining center, etc.). Process focus

Aerospace Parts Rapid Prototypes is an important symbol of my country's scientific and technological development and an important manifestation of the improvement of comprehensive national strength.

CNC stands for Computerized Numerical Control. It is a computerized manufacturing process in which pre-programmed software and code controls the movement of production equipment.
