5238-E P-139SECTION 7 FIXED CYCLES8-3. Address Characters8-4. M Codes• For designating key way cutting directionM211: One-directional cuttingM212: Zigzag cutting• For designating key way cutting methodM213: Designated infeedM214: Equal infeedX : For cutting on an end face and longitudinal thread cutting, "X" indicates the X-coordinateof the cycle starting point.For cutting on an OD and transverse thread cutting as well as key way cutting, "X"indicates the X-coordinate of the end point of the cycle.Z : For cutting on an end face and longitudinal thread cutting as well as key way cutting, "Z"indicates the Z-coordinate of the end point of the cycle.For cutting on an OD and transverse thread cutting, "Z" indicates the Z-coordinate of thestarting point of the cycle.C : C-axis indexing angleI : Shift amount in the G00 mode for cutting on an OD, cutting starting point in transversethread cutting cycle, end point of taper thread in longitudinal thread cutting cycleJ : Number of threadsK : Shift amount in the G00 mode for cutting on an end face, cutting starting point inlongitudinal thread cutting cycle, end point of taper thread cutting in transverse threadcutting cycleF : Cutting feedrateD : Depth of cut per peck feed in deep-hole drilling and key way cuttingStart position of tapping with M-tool spindle in synchronized tapping.E : Duration of dwell motion at the end point in drilling, boring and tapping cycle (omissible)Infeed amount in key way cuttingL : Axis relieving amount in deep-hole drilling cycleU : Finish allowance in side key way cuttingW : Finish allowance in face key way cuttingSA = : Programmable only in multiple-fixed cycle of G185 through G188 (thread cutting cycles).C-axis rotation speed command.This SA= command is programmed to obtain the axis movement amount of the C-axis inG185 through G188 thread cutting cycles.R : Infeed amount for drilling cycleSpecify the distance from the cutting starting point. Thesign of the R command indicates the direction of cutting.An R command in the X-axis direction should be given as a diametral value.Q : The number of holes (equally spaced) to be machined using the multiple-fixed cyclerepeat function
