摘要:
An operating information input method in a numerical control apparatus which executes prescribed numerical control processing based on numerical control program data and operating information includes steps of designating the start of operating information input displaying, on the screen of a display device, various operating information items (e.g. MODE, HANDLE AXIS, and HANDLE *10) e.g. and selectable items (MDI, AUTO, EDIT, HNDL, JOG, ZRN, HX, HZ) in the form of characters in response to designating the start of inputting operating information positioning a first cursor (CSR) on a line of an operating information item to be input, thereafter positioning a second cursor associated with the operating information item designated by the first cursor, on a line of a prescribed selectable item to identify the desired operating information based on the positions of the first and second cursors.
摘要:
A numerical control method for a numerical control system having a numerical control unit (NC) for numerically controlling a machine tool or the like, as well as a programmable controller unit (PC), wherein when machining is suspended and then resumed, the NC unit (1) runs the machining program from the beginning of the machining program up to a prescribed block at which machining is to be resumed, without peforming a distribution operation. During running of the program, data regarding M-, S- and T-functions in the machining program are successively delivered to and stored in the PC unit (2). At this time the PC unit (2) does not send these data to the machine side. Machining is resumed at the conclusion of a search operation up to the prescribed block. However, since the M-, S- and T-functions have already been set automatically in the PC unit (2) to conditions exactly the same as those that prevailed at the suspension of machining, the machining operation can be resumed smoothly from the instant of machining resumption.

A tapping machining method for moving a tapping tool to a commanded position in synchronism with rotation of a spindle, to subject a workpiece to threading, and thereafter rotating the spindle in the reverse direction and withdrawing the tapping tool from the workpiece in synchronism with rotation of the spindle. The steps of the tapping machining method include moving and positioning a spindle, namely the tapping tool (4), from an initial point (Pi) to an approach point (Pr) in the depth direction (along the Z axis) while being rotated at a constant velocity. Then a pulse distribution calculation is started by using the pitch of a screw and pulses of a frequency proportional to the rotational velocity of the spindle, and threading is performed while the tapping tool is moved toward a target position (Pe) by the distributed pulses. Next, a spindle reverse rotation command is produced for rotating the spindle in the reverse direction without halting the pulse distribution calculation, even when the tapping tool arrives at the target position (Pe). Thereafter, the tapping tool is moved in the depth direction in synchronism with rotation of the spindle during forward due to inertial rotation. The tapping tool (4) is raised up to the approach point (Pr) by the distributed pulses after the spindle rotates in the reverse direction at a point (Pm), and the pulse distribution operation is ended after the tapping tool arrives at the approach point (Pr).
摘要:
A machining end detecting device detects whether each hole or the like has completely been drilled to its bottom or not, and the latest drilling information is stored in a nonvolatile memory. In the nonvolatile memory are also stored modal data sequence numbers assigned to drilling start position determining blocks and the latest information on a drilling restart position. Upon inputting a drilling restart command from key input means such as a cycle start button, a restart block indexing device indexes, from a numerical control machining program, a restart block necessary for resuming drilling of an unfinished hole or the like on the basis of the sequence numbers and the machining end detection information stored in the nonvolatile memory. A restart positioning device positions a drilling machine at the drilling start position stored in the nonvolatile memory, and a control device causes the drilling machine to restart with the indexed restart block from the specified position.
摘要:
A numerical control system wherein operation information is output in the form of a numeric code by numeric keys (KEY) disposed on a numerical control operator's panel (MDI). A numerical control unit (OPCN) into which the numeric code has been fed converts the numeric code into a character using a code converter (CC) and displays the character on a display unit (CRT). The operation information displayed on the display unit (CRT) is stored in an operation information memory (OIM), and the numerical control unit (OPCN) performs numerical control processing based on the stored operation information.
摘要:
In a numerical control system for a machine tool using a general-purpose motor (11) in place of at least one of servo motors, a current position of a spindle (10) driven by the general-purpose motor (11) is detected (14, 9) and is compared with a position designated by a numerical control program. When the current position approaches the position designated by the numerical control program, brake signals (MBR, BR) are generated to brake the general-purpose motor (11) or the like, and a rotation signal (MCW, MCCW) of the general-purpose motor (11) is disabled, thereby stopping the general-purpose motor (11) so as to cause the spindle (10) to stop at the position designated by the numerical control program.

摘要:
In an operation of setting a pause when registering a dial number, if a pause key is not input in immediate succession for a predetermined number of times, first pause data for generating a predetermined pause time is stored. If the pause key is input in immediate succession for a predetermined number of times, a mode for setting a pause time is provided, and second pause data for generating a pause corresponding to input time data is stored. When performing a call, a pause corresponding to stored pause data is generated.
