The present invention relates to methods and devices for monitoring a program for machining a component using a numerically controlled lathe 1 including a machine tool, controllable means for moving the said tool, and a programmable processing member capable of furnishing control signals for controllable means in order to move the tool. The method implemented by the device consists in replacing the tool with a tracing means 12 at a point 15, in arranging on a table 2 a sheet 16 reacting to the tracing means, in programming the processing member with the control program for the component to be produced, in controlling the controllable means 5 so as to move the tracing means 13 with respect to the table 2 using the programmed processing member, so as to mark the sheet using the tracing means in order to obtain a viewable figure, and finally, in comparing the figure obtained on the sheet to a template, in order to deduce therefrom the quality of definition of the said program part. <IMAGE>
