What is the editing instruction code of Shenyang machine tool CNC lathe? SMTCL-NC 100 system.

Program design of FANUC-0TD CNC lathe;

1. instruction set (all programming quantities in the x direction, such as x and u, are diameter quantities)

G00: Quick positioning instruction. The format is G00 X(U) Z(W), where x and z are the target points in absolute programming and u and w are the target points in relative programming. The two axes start moving at the fastest speed of the machine tool at the same time, but they don't necessarily stop at the same time, that is, the synthesized tool path is not necessarily a straight line. This system can be mixed programming, such as G00 X W.

G0 1: linear interpolation instruction. The format is G0 1 X(U) Z(W) F, where x and z are the target points in absolute programming, u and w are the target points in relative programming, and the value of f is interpolation speed in mm/min or mm/r, depending on whether it is set to G98 or G99.

G02: Circular interpolation instruction. The format is G02 X(U) Z(W) R(I K) F, where x and z are the target points in absolute programming, u and w are the target points in relative programming, r is the radius (only used for poor arc programming), i and k are the x and z coordinates of the center, and f is the interpolation speed in mm/min or mm/r, depending on the settings. Note: I use the radius quantity, and I and K are always programmed as relative quantities.

G03: Inverse circle interpolation instruction. The format is G03 X(U) Z(W) R(I K) F, where x and z are the target points in absolute programming, u and w are the target points in relative programming, r is the radius (only used in programming with poor arc), i and k are the x and z coordinates of the center, and f is the interpolation speed in mm/min or mm/r, depending on the setting. Note: I use the radius quantity, and I and K are always programmed as relative quantities.

G04: Pause the instruction. The format is G04 P(X U), when P is used (decimal point is not allowed), the time unit is ms, when X and U are used, the time unit is s, and the maximum delay is 9999.999s.

G20: English unit setting instructions.

G20 1: Description of setting metric units. Note: If G20 and G20 1 are not specified in the program, the settings from the last shutdown will be used.

G27: Return the reference point detection instruction. The format is G27 X(U) Z(W) T0000, and the tool rest must be reset once before executing this instruction. If the specified two coordinate values are the coordinate values of the machine tool reference point respectively, and the two zero-returning reference point indicators on the machine tool panel are all on, the machine tool zero point is correct. Otherwise, the positioning error of the machine tool is too large.

G28: Return to reference point instruction. The format is G28 X(U) Z(W) T0000. If the machine tool returns to zero after starting, the tool rest will return to zero after the specified point, otherwise it will move to the position when the system is powered on after the specified point.

G32: Thread cutting instruction. G32 X(U) Z(W) F, where f is the lead of the thread in the long axis direction (that is, the feed speed is mm/r).

G50: Workpiece coordinate system setting or spindle speed clamping instruction. The format is G00 X Z (coordinate system setting) or G50 S (speed clamping). In the former, XZ value is the coordinate of the zero point of the machine tool in the set workpiece coordinate system; In the latter, s is the highest speed.

G70: Complete the compound cycle. The format is G70 P Q S F, where P is equal to the starting number of the finishing program segment and Q is equal to the ending number of the finishing program segment.

G7 1: rough machining compound cycle. The format is

G7 1 U R, where u is equal to the feed or cutting depth in the x direction, and r is equal to the retract, all of which are radius values.

G7 1 P Q U W S F, where p is equal to the start number of the finishing program segment, q is equal to the end number of the finishing program segment, u is equal to the diameter value of the finishing allowance in the x direction, w is equal to the finishing allowance in the z direction, s is the spindle speed, and f is the feed speed.

G72: End surface rough machining cycle. The format is

G72 W R, where w is equal to the feed in the z direction and r is equal to the feed in the z direction.

G72 P Q U W S F where p is equal to the starting number of the finishing program segment, q is equal to the ending number of the finishing program segment, u is equal to the diameter value of the finishing allowance in the X direction, w is equal to the finishing allowance in the Z direction, s is the spindle speed, and f is the feed speed.

G73: Combined cycle of shaping and rough machining. The format is

G73 U W R, where u is equal to the tool feed radius value (or cutting depth) in X direction, w is equal to the tool feed in Z direction, and r is equal to the number of cycles.

G73 P Q U W S F, where p is equal to the start number of the finishing program segment, q is equal to the end number of the finishing program segment, u is equal to the diameter value of the finishing allowance in X direction, w is equal to the finishing allowance in Z direction, s is the spindle speed and f is the feed speed.

G90: Single cycle instruction for conical surface cutting. The format is G90 X(U) Z(W) R F, and the definition of the cone is that the slope of the prime line is less than or equal to 45 degrees. When rotating a cylinder, R=0, so don't write. The action (dashed line indicates fast) completed by this command is shown in figure 1, in which the tip of the knife cuts from the lower right to the left, r < 0, and the tip cuts from the upper right to the left, R>0. The coordinate values in the instruction are E-point coordinates.

G92: Single cycle instruction for taper thread cutting. The format is g92x (u) z (w) r f, and when turning column threads, R=0, which can be left blank. The action (dashed line indicates fast) completed by this command is shown in figure 1, in which the tip of the knife cuts from the lower right to the left, r < 0, and the tip cuts from the upper right to the left, R>0. F is the advance in the long axis direction. The coordinate values in the instruction are E-point coordinates.

G94: Single cycle instruction for face cutting. The format is G94 X(U) Z(W) R F, and the end face is defined as the slope of plain line ≥45 degrees. When turning a pure end face, R=0, so there is no need to write. The action completed by this command (dashed line indicates fast) is shown in Figure 2, where the tool tip cuts from upper left to lower right, r < 0, and the tool tip cuts from upper right to lower left, R>0. The coordinate values in the instruction are E-point coordinates.

G96: command of constant linear velocity of end face. The format is G96 S.

G97: Cancel the instruction of constant linear velocity at the end face. The format is G97.

M00: Program paused. When the Start button on the panel is pressed, the program will continue to run.

M02: The program ends.

M03: Spindle rotates forward.

M04: Spindle reversal.

M05: The spindle stops running.

M08: Open the cutting fluid.

M09: Turn off the cutting fluid.

M 10: automatic thread chamfering.

M 1 1: cancel M 10.

M30: The program ends and returns to the beginning.

M98 P: Call subroutine. The format is m98p * * * * * * the first three digits are the number of calls (if not, it means 1 time), and the last four digits are the program number of the tune.

M99: subroutine end flag.
