<p>PURPOSE:To confirm easily an NC working program by changing a color of a drawn picture of a tool locus by an input command. CONSTITUTION:An NC working program 1 is read by one block each, and is provided to a discriminating means 2 and a tool locus data generating means 3. The discriminating means 2 discriminates whether an inputted block is a color change designating block or not, by referring to an output of a color change designating means 4 for designating in which part of the NC working program a color of the tool locus is changed. A tool locus data corresponding to a block which is not a color change designating block and a tool locus data of the color change designating block are written in a graphic use RAM6 and a graphic use RAM7, respectively. Its contens are read out by synchronizing with a video signal generating means 8, and a color video signal is generated and is inputted to a color graphic part 9.</p> |
