Introduction This manual describes the specifications of MITSUBISHI CNC M700V Series. [. . . ] The method to select the operation mode are as follows: Initiates the interrupt by switching from the automatic mode to manual mode Initiates the interrupt by selecting the manual mode at the same time as the automatic mode (Refer to "11. 4. 9 Simultaneous Operation of Manual and Automatic Modes". ) Whether the manual interrupt amount is to be retained and automatic operation is to be continued is determined by setting manual absolute mode ON or OFF (refer to "11. 4. 3 Manual Absolute Mode ON/OFF"). III - 190 M700V Series Specifications Manual 11 Operation Support Functions 11. 4. 2 Automatic Operation Handle Interruption M720VW M system L system M730VW M750VW M720VS M730VS M750VS The handle command can interrupt and be superimposed onto a command without suspending automatic operation and the machine can be moved by rotating the manual pulse generator during automatic operation. If the spindle load is greatly exceeded when cutting a workpiece as per the machining program due to a high rough cutting amount in face machining, for instance, automatic handle interrupt makes it possible to raise the Z surface and reduce the load easily without suspending feed in the automatic operation mode. Automatic handle interrupt is conducted by setting the "automatic handle interrupt" valid switch which is provided separately from the "manual operation mode". The axis selection, pulse scale factor and operation are conducted as for manual handle feed. Whether, after an interrupt, to return to the path of the machining program by automatic operation or remain offset by the amount equivalent to the interrupt amount is determined using a parameter.

In other words, the coordinate system based on the original program will not shift even if the tool (machine) is moved by hand. Thus, if automatic operation is started in this case, the tool will return to the path before manual movement.

III - 193 MITSUBISHI CNC III Functional Specifications 11. 4. 4 Thread Cutting Cycle Retract M720VW M system L system M730VW M750VW M720VS M730VS M750VS This function suspends the thread cutting cycle if a feed hold signal has been input during thread cutting in a thread cutting cycle. If a feed hold signal is input during chamfering or thread cutting without chamfering, operation stops at the position where the block following the thread cutting is completed.

Z SP (a) (b) (c) (d) (a) Tap feed (spindle forward) SP (spindle) (b) Tap retract (spindle reverse) (c) Retract signal (d) Tap bottom This function can be used when the machining was interrupted upon reset, emergency stop or power OFF during tapping cycle. (Note that "power OFF" is applied only when the absolute position detection system is valid. ) A return is made to the initial point by tap retract. III - 195 MITSUBISHI CNC III Functional Specifications 11. 4. 6 Manual Numerical Value Command M720VW M system L system M730VW M750VW M720VS M730VS M750VS On the screen of the setting and display unit, the M, S and T (and B when 2nd miscellaneous function is valid) commands can be executed by setting numerical values and pressing [INPUT]. This enables operations such as spindle speed changing, starting, stopping, calling and selecting assigned tools and replacing of the spindle tools to be done easily without having to prepare or revise the machining program. Even in an automatic operation mode, these operations can be conducted with block stop. Furthermore, the M and T commands can be issued even on the tool compensation amount setting and display screen, therefore at the manual tool length measurement, the tools can be called successively to the spindle and measured very simply without having to change the screen page.

The following steps are available: Execute the reverse run to the point to go back, Run the reversed blocks again following the program (hereinafter called "forward run") and Continue the remaining blocks from the point of the interruption. Only the 1st to 3rd axes of each part system can be used for this function.

When the modal status is changed in the MDI program, the modal status in the automatic operation mode is also changed.
