Title:
NUMERICALLY CONTROLLED DEVICE WITH WORKING SIMULATION FUNCTION
Document Type and Number:
WIPO Patent Application WO/1992/008574
Kind Code:
A1
Abstract:
A numerically controlled device wherein, during working simulation, both a work and a tool are constantly displayed on a display screen at a proper variable display magnification, so that both of a change in shape of the work and movement of the tool can be constantly properly checked. The numerically controlled device is provided with a processor (11) for numerical control and a processor (31) for automatic programming. The processor (11) determines a scale so as to display the work over the full display screen of a display device (18), calculates a scale so that both of the work and the tool are contained within the display screen on the basis of the current position of the tool each time a numerical control program is executed on a block basis for working simulation, further, discriminates the necessity of a scale change on the basis of the result of comparison between the predetermined scale and a calculated scale and the scale used in displaying the previous program block, and changes the scale as necessary. The processor (31) performs working simulation on the display screen at a display magnification matching the determined scale.
