CNC Machining, Computer-aided Design, And Computer-aided Manufacturing Of CNC Equipment

It is a new type of processing technology, whose main job is to develop processing programs and convert manual work into computer programming. The feed machining route of a CNC machine tool refers to the path that the turning tool passes through from the tool point to the point where it returns and ends the machining program, including the cutting path and the tool's entry and exit. The non cutting empty stroke path, while the feed path of precision machining is basically carried out in the order of its part contour. Therefore, the key to determining the route is. Determine the feed path for rough machining and empty stroke. CNC machining refers to the machining performed using CNC machining tools. CNC refers to a CNC machine tool that is programmed and controlled by a CNC machining language, usually G code. The CNC machining G code language tells the machining tool of the CNC machine tool what kind of Cartesian position coordinates to use, and controls the feed rate and spindle speed of the tool, as well as functions such as tool coolers and cooling agents. The most common CNC machining methods include CNC milling, CNC turning, and CNC EDM wire cutting.

Using computer assistance to complete the entire process from production preparation to product manufacturing, that is, by directly or indirectly connecting computers with manufacturing processes and production equipment, using computer systems to plan and manage the manufacturing process, control and operate production equipment, process data required in the product manufacturing process, and control and process the flow of materials (blanks and parts, etc.), Test and inspect the product, etc.

The core is computer numerical control (CNC programming for short), which generates NC codes that machine tools can read through computer programming, making the operation of machine tools more accurate and efficient, and saving a lot of costs for enterprises.

The CAM software available on the market includes UG NX, Pro/NC, CATIA, and CAD/CAM. Regarding the machine's far point, the engraving machine is a working unit controlled by a CNC system. The system itself only knows the current position relative to the previous position, and a reference point needs to be selected so that any position on the machine has a fixed coordinate as a parameter. This reference point is the machine's far point. Ensure that there is only one limit position in the X, Y, and Z directions of the machine.

Regarding the work origin, it refers to the origin of the work coordinates, which is determined by programming the work size. The work origin can be selected by the programmer and is generally the starting point for workpiece processing. When the "Return to workpiece origin" option is selected, the tool tip will automatically return to the working origin from the current position, and the tool tip will actively return to the working origin from the current position. The working origin can be set at any position of the machine's stroke and saved multiple times.
