摘要:
When NC programs of a simultaneous four-axis lathe have been prepared, a processor (11) obtains the machining times T.sub.1i, T.sub.2i of synchronized processes for each tool rest and obtains total machining time T.sub.m for machining performed by the simultaneous four-axis lathe by using the longer of the machining times for those synchronized processes carried out simultaneously by the tool rests. Next, the total machining time T.sub.m is divided by the number of characters C in the horizontal direction of a CRT (16d) used in displaying bar graphs, to calculate machining time t per character. The machining time of each synchronized process is divided by the obtained machining time t per character, to determine the number of characters necessary for displaying each machining time. Thereafter, the machining time for each tool rest is displayed in the form of a bar graph on the display screen of the CRT (16d) by allotting character patterns for bar graph display stored beforehand in a character generator (16b) to the numbers of characters and respective machining times.
摘要:
A numerical control system applies standby commands, through external pushbutton switches or the like, to tool bases which operate on a first trial basis or by way of graphics machining simulation and are required to wait in a standby mode, stores standby data by removing the standby commands, and effects standby control on the tool bases based on the stored standby data during actual machining operations.
摘要:
A numerical control system in which a numerical control device is adapted to control a machine tool equipped with a plurality of tables, as one example, on which workpieces may be secured to be machined by a tool mounted on a head. A table which is not being controlled automatically by the numerical control device can be operated independently of the automatic operation network of the numerical control device and placed in a manual operation mode or manual data input mode in which the table can be moved manually even while the numerical control device controls the other table or tables automatically.
