Machining process of NC machine tool

Machining CNC lathe processing refers to the process of machining parts on CNC machine tools. CNC machine tool is a machine used to control the machine tool, used to control the machine tool computer, whether the special computer, or general computer are all known as numerical control system. The movement and auxiliary actions of CNC machine tools are controlled by the instructions issued by NC system.
The instructions of the CNC system are compiled by the programmer based on the material, processing requirements, the characteristics of the machine tool and the instruction format specified by the system (NC language or symbol). The CNC system controls the motion of the machine tool according to the program instructions to send servo or other functional parts to run or terminate information. When the parts processing program is finished, the machine tool will stop automatically. A CNC machine tool can not work without input instructions in its CNC system.

The controlled action of machine tool consists of the starting and stopping of the machine tool; the starting and stopping of the spindle, the rotation direction and the transformation of the speed; the direction, the speed and the way of the feed movement; the compensation for the choice of the tool, the length and the radius of the tool; the replacement of the tool, the opening and closing of the coolant, etc.
The CNC machine tool selected the aircraft parts with complex surface as the processing objects at the very beginning, and solved the key problem that the ordinary machining methods were difficult to solve.  The most important feature of NC machining is to use perforated tape (or tape) to control machine tools for automatic processing.
The aircraft, rocket and engine parts have different characteristics: the aircraft and the rocket are zero, the component size is large, the surface is complex, the engine zero, the small size, high precision.
Therefore, the machined aircraft, the rocket manufacturing department and the engine manufacturing department choose the numerical control machine tool to be different. Large numerical control milling machines with continuous control are used in aircraft and rocket manufacturing, while continuous control CNC machine tools are used in engine manufacturing, and numerical control machines (such as NC drilling machine, NC boring machine, machining center, etc.) are used as well as point position control.
