Abstract
Abstract A numerical control device (CPU) stores dimensional details of a workpiece, a chuck, and a tailstock as coordinate data Items in a memory, computes the positions and shapes of the workpiece, the chuck, and the tailstock based on the coordinate data items, and displays the workpiece, the chuck, and the tailstock as graphic patterns on a display unit based on the computed results. The computation may be simplified by using coordinates of a relative coordinate system as the coordinate data items for graphic display.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
88 words
A numerical control device characterised by: a controller (CPU) for controlling a machine tool having first and second holder mechanisms (10, 12) for jointly holding a workpiece (11); a graphic display unit coupled to said controller (CPU) for displaying the workpiece (11) as held by said first : and second holder mechanisms (10, 12) in accordance with data indicative of dimensional details of said workpiece (11), dimensional details of said first holder mechanism (10), and dimensional details of said second holder mechanism (12) entered into said controller (CPU).
Claim 2
Dependent Claim
88 words
A numerical control device characterised by: a controller (CPU) for controlling a machine tool having first and second holder mechanisms (10, 12) for jointly holding a workpiece (11); a graphic display unit coupled to said controller (CPU) for displaying the workpiece (11) as held by said first : and second holder mechanisms (10, 12) in accordance with data indicative of dimensional details of said workpiece (11), dimensional details of said first holder mechanism (10), and dimensional details of said second holder mechanism (12) entered into said controller (CPU).
Claim 3
Dependent Claim
