Method and device for machining contoured recesses, utilizing a graphical user interface for defining contour expressions

摘要

In a method for machining a contoured recess, a digital control is used to predetermine elementary surfaces, which are linked in a contouring expression using logical operators to form a resulting surface. Various help types are offered to the user on a graphical user interface of the digital control. The operators are explained using graphic symbols and help text. The resultant surface is represented on the user interface.
