Machining debugging method for realizing path positioning by inverse solution of numerical control programming instruction

The invention discloses a processing debugging method for realizing path positioning by inverse solution of a numerical control programming instruction. The method comprises the following steps: 1) loading a processing program on a controller; 2) entering a debugging page, and displaying a simulation graph of a processing path; 3) clicking primitives needing to be modified, and a program jumping to a corresponding processing line and being displayed in a highlight mode; 4) editing and modifying a processing stroke formula, and refreshing a simulation graph in real time; and 5) clicking storage, and loading a program to execute processing. According to the processing debugging method for realizing path positioning through inverse solution of the numerical control programming instruction, an operator can click a geometric primitive on a touch screen through a finger or a mouse, a program processing line corresponding to the primitive is quickly positioned, online editing is supported, a path is refreshed in rea
