NC: Select first input field in previous/next frame About this Manual The symbols used in this manual are described below. This symbol indicates that important notes about the function described must be adhered to. This symbol indicates that there is one or more of the following risks when using the described function: Danger to workpiece Danger to fixtures Danger to tool Danger to machine Danger to operator This symbol indicates that the described function must be adapted by the machine tool builder. The function described may therefore vary depending on the machine. This symbol indicates that you can find detailed information about a function in another manual. Would you like any changes, or have you found any errors? We are continuously striving to improve documentation for you. [. . . ] Input If you enter M118 in a positioning block, the TNC continues the dialog for this block by asking you the axis-specific values. The coordinates are entered with the orange axis direction buttons or the ASCII keyboard. Effect Cancel handwheel positioning by programming M118 once again without coordinate input. M118 becomes effective at the start of block. Example NC blocks You want to be able to use the handwheel during program run to move the tool in the working plane X/Y by ±1 mm and in the rotary axis B by ±5° from the programmed value: L X+0 Y+38. 5 RL F125 M118 X1 Y1 B5 M118 is always effective in the original coordinate system, even if the working plane is tilted. In a program with millimeters set as unit of measure, the TNC interprets M118 values for linear axes in millimeters. In an inch program it interprets it as inches. M118 also functions in the Positioning with MDI mode of operation!M118 in combination with DCM collision monitoring is only possible in stopped condition (blinking control-inoperation symbol). If you try to move an axis during handwheel superimposition, the TNC will generate an error message. HEIDENHAIN iTNC 530 365 10. 4 Miscellaneous Functions for Contouring Behavior 10. 4 Miscellaneous Functions for Contouring Behavior Retraction from the contour in the tool-axis direction: M140 Standard behavior In the program run modes, the TNC moves the tool as defined in the part program. Behavior with M140 With M140 MB (move back) you can enter a path in the direction of the tool axis for departure from the contour. Input If you enter M140 in a positioning block, the TNC continues the dialog and asks for the desired path of tool departure from the contour. Enter the requested path that the tool should follow when departing the contour, or press the MB MAX soft key to move to the limit of the traverse range. In addition, you can program the feed rate at which the tool traverses the entered path. If you do not enter a feed rate, the TNC moves the tool along the entered path at rapid traverse. Effect M140 is effective only in the block in which it is programmed. M140 becomes effective at the start of the block. Example NC blocks Block 250: Retract the tool 50 mm from the contour. Block 251: Move the tool to the limit of the traverse range. 250 L X+0 Y+38. 5 F125 M140 MB 50 F750 251 L X+0 Y+38. 5 F125 M140 MB MAX M140 is also effective if the tilted-working-plane function, M114 or M128 is active. On machines with tilting heads, the TNC then moves the tool in the tilted coordinate system. With the FN18: SYSREAD ID230 NR6 function you can find the distance from the current position to the limit of the traverse range in the positive tool axis.
