차례로 접속된 패치에 의하여 형성된 자유곡면을 절삭 목표로 하여 공구의 이동경로를 나타내는 옵셋곡면데이터를 생성하는 옵셋곡면데이터 작성방법에 있어서, 상기 패치에 대향하는 제1의 옵셋곡면을 나타내는 제1의 데이터와, 상기 패치의 경계곡선중 접평면(接平面) 연속의 조건을 만족하지 않는 경계곡선상의 위치에 대하여 소정의 반경만큼 떨어진 위치에 형성된 관형(管形)곡면을 가진 제2의 옵셋곡면을 나타내는 제2의 데이터를 작성하고, 상기 제1의 데이터에 대하여 상기 제2의 데이터를 보간하므로서, 상기 접평면 연속의 조건을 만족하지 않는 경계곡선을 상기 공구가 건널때에 절삭목표가 되는 상기 자유곡면을 과도하게 절삭하지 않는 이동경로를 형성하는 것을 특징으로 하는 옵셋곡면 데이터 작성방법.An offset surface data generation method for generating offset surface data representing a path of movement of a tool, with a free curved surface formed by a patch connected in turn, wherein the first data represents a first offset surface facing the patch. And a second offset curved surface having a tubular curved surface formed at a position separated by a predetermined radius with respect to a position on a boundary curve that does not satisfy a condition of continuous tangent plane among the boundary curves of the patch. By creating the data of 2 and interpolating the second data with respect to the first data, the free curved surface which becomes the cutting target when the tool crosses a boundary curve that does not satisfy the condition of the tangent plane continuous is excessively exceeded. A method of creating offset surface data, characterized by forming a moving path that is not cut. 차례로 접속된 패치에 의하여 형성된 자유곡면을 절삭목표로 하여 공구의 이동경로를 나타내는 옵셋곡면데이터를 생성하는 옵셋곡면데이터 작성방법에 있어서, 상기 패치에 대향하는 제1의 옵셋곡면을 나타내는 제1의 데이터와, 상기 패치의 경계곡선중 접평면 연속의 조건을 만족하지 않는 경계곡선상의 위치에 대하여 소정의 반경만큼 떨어진 위치에 형성되는 관형 곡면을 가진 제2의 옵셋곡면을 나타내는 제2의 데이터와, 상기 패치의 경계곡선의 끝부에 있는 각부(角部)중 뾰족한 각부에 대하여 소정의 반경만큼 떨어진 위치에 형성되는 구형(球刑)곡면을 가진 제3의 옵셋곡면을 나타내느 제3의 데이터와를 작성하고, 상기 제1의 데이터에 대하여 상기 제2 및 제3의 데이터를 보간하므로써, 상기 접평면 연속의 조건을 만족하지 않는 경계곡선 및 상기 뾰족한 각부를 상기 공구가 건널때에 절삭목표가 되는 상기 자유곡면을 과도하게 절삭하지 않는 이동경로를 형성하는 것을 특징으로 하는 옵셋곡면데이터 작성방법.An offset surface data generating method for generating offset surface data indicating a path of movement of a tool, with a free curved surface formed by a patch connected in sequence, wherein the first data indicates a first offset surface facing the patch. And second data indicating a second offset curve having a tubular curved surface formed at a position spaced apart by a predetermined radius from a boundary on the boundary curve of the patch that does not satisfy the condition of a tangent plane continuous. A third data plot representing a third offset curve having a spherical curved surface formed at a position separated by a predetermined radius of the sharp corners of the corners at the end of the boundary curve of A boundary curve that does not satisfy the condition of the tangent plane continuous by interpolating the second and third data with respect to the first data; A method of creating offset surface data, characterized by forming a moving path in which the sharp corners do not excessively cut the free curved surface which becomes the cutting target when the tool crosses. ※참고사항:최초출원 내용에 의하여 공개하는 것임.※ Note: This is to be disclosed based on the first application.
