After playing with these, you have entered the door of CNC programming with  3 axis cnc milling machine 1165 4 advantages  !

3 axis cnc milling machine 1165 4 advantages Programming is to program the process of processing parts, process parameters, workpiece size, direction of tool displacement and other auxiliary actions (such as tool change, cooling, loading and unloading of workpieces, etc.) according to the sequence of motion according to the programming format The process of writing a program sheet with instruction codes. The written procedure sheet is the processing procedure sheet.

Determination of machine tool coordinate system and direction of motion

The X, Y, and Z coordinate systems of the linear motion of the machine tool adopt the right-handed Cartesian coordinate system, as shown in Figure 11-6. The coordinate axis definition sequence is to determine the Z axis first, then the X axis, and finally the Y axis. For a machine tool that rotates the workpiece (such as a lathe), the direction in which the tool moves away from the workpiece is the positive direction of the X axis; for a machine tool that rotates the tool (such as a vertical milling machine), when the tool is on the Z axis, the direction facing the tool spindle to the column Look, the right direction is the positive direction of the X axis.

The coordinate systems of the three rotation axes are parallel to the X, Y, and Z coordinate axes respectively, and the forward direction of the right-hand thread is taken as the positive direction.

Basic instructions for CNC lathes

1) Program format

A machining program usually consists of three parts: program start, program content and program end.

The beginning of the program is the program number, which is used to mark the start of the machining program. The program number is usually represented by the character "%" followed by four digits.

The end of the program can be indicated by auxiliary functions M02 (end of program), M30 (end of program, return to starting point) and so on.

The main content of the program is composed of several program segments (BLOCK), the program segment is composed of one or several information words, and each information word is composed of address characters and data characters. An information word is the smallest unit of an instruction.

2) Program segment format

Currently, word address block format is commonly used, and the application standard is JB3832-85.

The following is a typical word address block format:

N001 G01 X60.0 Z-20.0 F150 S200 T0101 M03 LF

Among them, N001—indicates the first block

G01—indicates linear interpolation

X60.0 Z-20.0―respectively represent the movement amount in the X and Z coordinate directions

F, S, T—indicates feed speed, spindle speed and tool number respectively

M03 - means the spindle rotates clockwise

LF—indicates the end of the program segment

3) Basic function codes in the CNC system

(1) Block number: N10, N20...

(2) Preparation function: G00-G99 is the function to make the numerical control device do some kind of operation.

G codes are divided into modal codes and non-modal codes. The so-called modal code means that a certain G code (G01) is always effective once it is specified, and it cannot be replaced until the same group of G codes (G03) is used in the following program segment. Non-modal codes are only valid in the specified block, and must be rewritten when needed in the next block (such as G04).

a. Quick point positioning command G00

The G00 command is a modal code, which commands the tool to move rapidly from the point where the tool is located to the next target position in the point positioning control mode. It is only fast positioning, but no motion trajectory requirements.

The writing format of the command is: G00 X_Z_; the actual movement route of the tool is not a straight line, but a broken line, so when using the G00 command, pay attention to whether the tool interferes with the workpiece clamp. Collisions are more dangerous.

b. Linear interpolation command G01

The linear interpolation command is a linear motion command and also a modal code. It commands the tool to move linearly with any slope at the specified F feed speed (unit: mm/min) in interpolation linkage between two coordinates or three coordinates.

The command writing format is: G01 X_Z_F_; F command is also a modal command, which can be canceled by G00 command. If there is no F command in the block before the G01 block, the machine tool will not move. Therefore, there must be an F command in the G01 program.

c. Circular interpolation command G02/G03 (judged by Cartesian coordinates)

The circular interpolation command commands the tool to move in a circular arc at the given F feed speed in the specified plane to cut out the circular arc contour. When machining an arc on a lathe, not only must use G02/G03 to indicate the clockwise direction of the arc, use XZ to specify the end point coordinates of the arc, but also specify the radius of the arc.

The command writing format is: G02/G03 X＿Z＿R＿;

(3) Auxiliary function: used to specify the auxiliary actions of the machine tool (such as machine tool start and stop, steering, cutting fluid switch, spindle steering, tool clamping and releasing, etc.)

M00－Program pause

M01 - Program Plan Suspended

M02－end of program

M03－spindle forward rotation (CW)

M04－spindle reverse (CCW)

M05－spindle stop

M06－Machining center tool change

M07, M08 - coolant on

M09 - Coolant OFF

M10 - Work clamping

M11 - Workpiece release

M30－The end of the program, return to the starting point

M05 command must be used to stop the spindle between M03 and M04 commands.

(4) Feed function F

If the direct designation method is used, directly write the required feed speed after F, such as F1000, indicating that the feed rate is 1000mm/min); when threading, tapping and buckle, because the feed speed is related to the spindle speed, The number after F is the specified lead.

(5) Spindle function S

S specifies the spindle speed, such as S800, means the spindle speed is 800r/min.

(6) Tool function T

Instruct the CNC system to change the tool, use the address T and the following 4 digits to specify the tool number and tool compensation number (tool offset number). The first 2 digits are the tool serial number: 0~99, and the last 2 digits are the tool compensation number: 0~32. The tool compensation must be canceled after machining of each tool.

The tool serial number can correspond to the tool position number on the cutter head;

Tool compensation includes shape compensation and wear compensation;

The serial number of the tool and the compensation number of the tool do not have to be the same, and they can also be consistent for convenience.

In the numerical control device, the record of the program is distinguished by the program number, that is, calling or editing the program must be called out through the program number.

a. The structure of the program number: O;

The number behind "O" is represented by 4 digits (1~9999), and "0" is not allowed.

b. Block sequence number: add sequence number before the block, such as: N;

The number behind "O" is represented by 4 digits (1~9999), and "0" is not allowed.

Workpiece coordinate system setting

The workpiece is installed on the chuck, and the coordinate system of the machine tool and the coordinate system of the workpiece generally do not coincide. For the convenience of programming, a workpiece coordinate system should be established so that the tool can process in this coordinate system.

G50 X Z

This instruction specifies the distance from the starting point of the tool or the tool changing point to the origin of the workpiece, and the coordinates X and Z are the starting point of the tool tip in the workpiece coordinate system.

For CNC machine tools with tool compensation function, the tool setting error can be compensated by tool offset, so the requirements for adjusting the machine tool are not strict.

Basic tool setting method of CNC lathe

There are three commonly used tool setting methods: trial cutting tool setting method, mechanical detection tool setting instrument tool setting, and optical detection tool setting instrument tool setting method.

Using G50 U W can make the coordinate system shift, and replace the old coordinate value with the new coordinate value, so that the machine tool coordinate system and the workpiece coordinate system replace each other. It should be noted that in the machine tool coordinate system, the coordinate value is the distance from the tool post center point to the machine origin; while in the workpiece coordinate system, the coordinate value is the distance from the tool tip to the workpiece origin.
