Graphic display device for nc machine tool

Abstract

Abstract PURPOSE:To read easily and exactly a shape, a dimension, etc. of an object by providing the same scale as a reduction or magnification rate of an object displayed actually, and displaying a coordinate of an XYZ coordinate axis whose original point is a desired point of the object. CONSTITUTION:A reduction (or magnification) rate operating means (a) reads out a reduction (or magnification) rate of an object, which is stored in an NC machine tool, changes a unit to it, and sets it as a reduction (or magnification) rate of an XYZ coordinate axis. An original point input means (b) keys in a desired address and sets an optional point as an original point. An XYZ axis input means (c) reads out a stored numerical information, and inputs a desired line as a coordinate axis. A reference XYZ axis display means (d) displays a reference coordinate axis by using a subroutine which the machine has. Various change input means e1, e2 change a unit by multiplying a unit of an information from a memory by a cosine of a variation angle. An after-change XYZ axis display means (f) displays each coordinate axis corresponding to the object of a changed attitude by using the subroutine.
