METHOD OF DEFINING MACHINING

摘要

Unmachined areas are displayed on a CRT screen clearly, and further, the candidates of the optimal tools for the next machining are displayed. A method for defining machining in which areas to be machined and the tools for the machining are designated comprises a first step of displaying the contour of designated areas to he machined; a second step of displaying the contour of areas actually machined by the designated tools; a third step of displaying the contour obtained in the first step and the contour obtained in the second step in superposition; and a fourth step of determining whether or not there is any area unmachined by the designated tools in accordance with the result of the display in the third step, and displaying the candidate tools for machining the unmachined area.
