What does the CNC lathe instruction M50 mean?

The auxiliary function word is used to specify the direction of rotation of the spindle, start, stop, and coolant.

Functions such as switching, clamping and unclamping of workpieces or tools, changing of tools, etc. The accessibility word consists of the address character M followed by two digits. The JB3208-83 standard is specified in the following table:

** Function Range Function ** Function Range Function M00 * Program Stop M36 * Feed Range 1 m01 * End of Plan M37 * Feed Range 2 m02 * End of Program M38 * Spindle Speed Range 1 m03 Spindle clockwise.

What kind of CNC system do you have? Most systems don't have the M command M50, M05 does, and M05 means spindle stop.

This is the code name for Q9001 or later, and is used in the automatic feeding program, and M50 is added to the program

M ** is the inside of the machine tool**, and various types of machine tools may be different.

CNC milling machine M5 is also M05, which means that the spindle stops.

Representation of other letters:

M is the auxiliary machine tool instruction issued by the CNC machining center, although the machine tools of each manufacturer are set differently because of the different production, but most of the key controls are still the same, such as M0 means the program is suspended when the machine is working, M1 means the selection stops, M2 means the end of the program, M3 means the spindle is rotated, M4 means the spindle is reversed, M5 means the pure nano spindle stops, M6 means the tool exchange, M8 means the cooling open, M9 means the cooling off, these are usually used, There are also letters in front of the numbers that have specific meanings, such as: d for the compensation number, f for the feed speed, g for the preparation function, m for the auxiliary function, etc.

Numerical control: Numerical Control (NC digital control) refers to the technology of using digital instructions composed of numbers, words and symbols to realize the action control of one or more mechanical equipment. It usually controls mechanical quantities such as position, angle, velocity, etc., as well as switching quantities related to the direction of mechanical energy flow.

The generation of numerical control depends on the emergence of data carriers and binary form data operations.

In 1908, perforated metal sheet interchangeable data carriers were introduced; At the end of the 19th century, a control system with paper as a data carrier and auxiliary functions was invented; In 1938, Shannon carried out rapid data computing and transmission at the Massachusetts Institute of Technology in the United States, laying the foundation for modern computers, including computer numerical control systems.

CNC technology is closely combined with machine tool control to develop and do nothing. In 1952, the first CNC machine tool came out, which became an epoch-making event in the history of the world's machinery industry and promoted the development of automation. <

CNC milling machine. M5 is also M05, which means the spindle stops.

Extended information: M is the auxiliary machine tool instruction issued by the CNC machining center, although the machine tool of each manufacturer is set up differently because of the different production, but most of the key controls are still the same, such as when the machine tool is working skillfully, M0 means that the program is paused, M1 means that the selection stops, M2 means the end of the program, M3 means the spindle is rotated, M4 means the spindle is reversed, M5 means the spindle is stopped, M6 means the tool is exchanged, M8 means the cooling is on, and M9 is the cooling off, These are commonly used, and the word in front of the number is also a specific meaning, such as: d represents the compensation number, f represents the feed speed, g represents the preparation function, m represents the auxiliary function, etc.

1. CNC instructions are mainly G, M, S, T**.

2. G** is the interpolation instruction in the numerical control program. It is commonly referred to as the G-Directive**. m is defined as an accessibility feature.

m** plays an auxiliary control role in the machine tool. s, Spindle Speed Command. t**Tool change instruction**.

3. CNC lathe is one of the most widely used CNC machine tools. It is mainly used for the cutting of the inner and outer cylindrical surfaces of shaft parts or disc parts, the inner and outer conical surfaces of arbitrary taper angles, the internal and external curved surfaces of complex rotary and cylindrical and tapered threads, and can be used for grooving, drilling, reaming, reaming and boring.

Fourth, the CNC machine tool is in accordance with the pre-prepared processing program, automatically processing the processed parts.

We write the Kaga school cavity process route, process parameters, tool movement trajectory, displacement, cutting parameters and auxiliary functions of the parts into a processing program list in accordance with the instructions and program format specified by the CNC machine tool, and then record the content of the program sheet on the control medium, and then input it into the CNC device of the CNC machine tool, so as to direct the machine tool to process parts.

The instructions of the representative of the CNC lathe are as follows:

The numerical control instructions are mainly G, M, S, T**.

It is commonly referred to as the G-Directive**.

**Spindle Speed Command**.

t**Tool change instruction**.

g** is an interpolation instruction in a numerical control program.

m Instruction Accessibility.

The M00 program is paused, and the NC start command can be used to make the program continue to run;

M01 is scheduled to be suspended, which is similar to M00, but M01 can be selected with the "optional stop button" of the machine tool to choose whether it is effective;

The M03 spindle rotates clockwise;

M04 spindle rotates counterclockwise;

M05 spindle rotation stops;

M08 coolant on;

M09 coolant off;

The M30 program stops and the program resets to the starting position.

In numerical control, M05 means spindle stop.

The CNC machining center m instruction is an auxiliary instruction in CNC machining. Depending on the machine tool manufacturer's settings, the M instructions for different machine tools are not the same, and the same M instructions are listed below.

M00 program pause, M01 selection stop, M02 program end, M03 spindle forward rotation, M04 spindle reversal, M05 spindle stop, M06 tool exchange, M08 cooling open, M09 cooling off, M18 spindle orientation release, M19 spindle orientation, M22 tool magazine return, M23 tool magazine into spindle, M29 rigid tapping, M30 program end and return to program head.

Summary. Absolute coordinate programming is often represented by x and z; Incremental coordinates are programmed with you and w, and can be programmed as absolute coordinates, incremental coordinates, or a mixture of both. --Generally, G90 and G91 commands are not used.

2) Because the blank commonly used in turning is bar or forging, the machining allowance is large, and various fixed cycle functions can be fully used to achieve the purpose of multi-cycle cutting. 3) The diameter direction is often expressed by the diameter value when programmed according to the absolute coordinates, and by 2 times the actual radial displacement when programmed according to the incremental coordinates.

3) The diameter direction is often expressed by the diameter value of the answer mold when programmed according to the absolute coordinates, and when the service balance is programmed according to the incremental coordinates, it is expressed by 2 times of the radial actual displacement.

G50 is the spindle speed control instruction (maximum speed limit) in the CNC machining technical instruction. In addition, there are the most commonly used instructions for setting coordinates on lathes.

CNC lathe coordinate establishment: g50 x z

The values of x and z are the positions of the starting point relative to the machining origin.

When programming CNC lathes, all x-coordinate values use diameter values.

Description: 1 Before executing this instruction, the tool must be set first, and the tool tip must be placed at the position of the starting point required by the program by adjusting the machine tool.

2 This command does not produce mechanical movements, but simply allows the system to replace the old coordinate values with new ones, thus creating a new coordinate system.
