What does N mean in CNC programming

n indicates the program segment number word.

The following table is followed by 4 or 2 as a number, such as n0010 or n10

Consciousness is the first stage of the procedure; Noo20 n20 is the case for paragraph 2.

on is used to distinguish between program paragraphs.

o: the program number, and the usage example is "o."

n: is a single section of the program, using the example "n1".

x0y0z0；

n2x0y0z0；……

The program end-of-section symbol, using the example "n1."

x0y0z0；

n2x0y0z0；”

User Macro Program A

The method of use is similar to that of a subroutine, except that in the macro program body, in addition to the usual CNC instructions, it is also possible.

Variable calculations are performed using CNC commands for variables, and macros can set the actual value of the variables. Variable.

The concept of variables.

Example: f 103, g00z- 100, g 130, 3) common variables and system variables.

Common variables (100 149, 500 531) are system variables. Tool offset (1, 99, 2000, 2200), interface input signal (1000, 1015, 1032), interface output signal (1100, 1115, 1132, 1133), timing information (3011, 3012).

Requires part counting and machining part counting information (3901, 3902) and modal information (4001, 4120).

Location information (5001 5083).

What does the P, Q, U, W, N of CNC lathe mean?

The p:p mode refers to the use of the same curve to represent the feed rate of the turning tool in the continuous machining process of the CNC lathe with a given turning depth. q：

Q mode means that the feed speed of the turning tool is different every time the turning depth of the CNC lathe is adjusted. u:u mode refers to the CNC lathe in the continuous machining process, each time the turning tool is reset, the feed speed of the turning tool is different.

w:w mode refers to the CNC lathe under the condition of a given turning depth, and the feed speed of the turning tool is different every time the turning depth is adjusted. n：

N mode means that in the continuous machining process of the CNC lathe, the feed speed of the turning tool is the same every time the turning tool is reset.

o is the program number, n is the program segment number, and the segment number of the program is the segment number of the program for example; N10 N20 Paragraph numbers can be omitted.

CNC lathes and turning centers are high-precision and high-efficiency automatic machine tools. Equipped with a multi-station turret or a driven turret, the machine tool has a wide range of processing performance, can process linear cylindrical, oblique cylindrical, circular arc and a variety of threads, grooves, worms and other complex workpieces, with linear interpolation, arc interpolation various compensation functions, and in the mass production of complex parts play a good economic effect.

N is usually two kinds, the first is to represent the meaning of the first, for example: n1, n2, this means the first and second meaning, and there is also a meaning to represent the force, if this n is marked on the axis indication or work instructions, then it means to represent the force, for example: 1500n, it represents the force of 1,500 N....The display screen of some CNC beds only has three digits, hundreds is thousands, and tens is hundreds

What you say n means rows, columns, e.g. n0022 you said! That's line 22!

M** can be used for any switch command, M03 M04 M05 M30 and other common ** general machine tool factories are uniformly used. Functions such as M10 depend on the machine tool factory settings.

o is the program number and n is the program segment number.

n represents a program segment, which is generally used when going through a loop. For example, the G71 P1 Q 2 of the lathe is followed by the cycle from N1 to N2.

n** only serves as a segment.

It mainly has the following functions.

1.When arranging the process, it is easy to find the corresponding program segment, such as O7007 (4283754).

G99N1G0G97S2000 (car end face).

m3/m8t0101

g0z50.

T100M1N2G0G97S600 (punch).

m3/m8t0102

t100m9m5

Behind the M30N1 is the end face of the car and behind the N2 is a punch.

2.I use it when I cycle it. For example, the G71 P1 Q 2 of the lathe is followed by the cycle from N1 to N2.
