数控g m代码（NC G M code） Give you something important! 1, G00 and G01 G00 motion track has two kinds of straight lines and broken lines. This instruction is only used for point positioning and can not be used for cutting G01 moves at a specified speed to the specified target point in a straight line motion, generally used for cutting 2, G02 and G03 G02: clockwise arc interpolation, G03:, counterclockwise arc interpolation 3, G04 (delay or pause instruction) Generally used for positive and reverse switching, processing blind hole, ladder hole, turning groove cutting 4, G17, G18, G19 plane selection instructions, specify plane processing, generally used in milling machines and machining centers The G17:X-Y plane may be omitted, or it can be a plane parallel to the plane of the X-Y G18:X-Z planes or planes parallel to them. In NC lathes only the X-Z plane is not specified G19:Y-Z planes or planes parallel to them 5, G27, G28, and G29 reference point instructions G27: returns the reference point, checking and confirming the reference point location G28: automatically returns the reference point (through the middle point) G28 returns from reference point and is used in conjunction with G29: 6, G40, G41, G42 radius compensation G40: cancel tool radius compensation Give it so much, and make it up in the evening 7, G43, G44, G49 length compensation G43: length positive compensation G44: length negative compensation G49: cancel tool length compensation 8, G32, G92, G76 G32: thread cutting G92: thread cutting, stationary cycle, G76: thread cutting, compound cycle 9, turning processing: G70, G71, 72, G73 G71: axial rough compound cycle instruction G70: finishing compound cycle G72: end turning, radial roughing cycle G73: profiling, roughing cycle 10 、 milling machine and machining center: G73: high speed deep hole peck drilling G83: deep hole peck drilling G81: drilling cycle G82: deep hole drilling cycle G74: left handed thread processing, G84: right-hand screw machining, G76: pr
