Title: Sweep curved surface creating device
Inventor: FUJII TATSUYA
IPC: G05B19/4097
Filed: 1987-10-13
Abstract: PURPOSE:To create a smooth sweep curved surface without generating deformation by providing a normal plane arithmetic means, an interpolation curved line preparing and sweep curved surface creating data storing means. CONSTITUTION:The device is provided with a guide line dividing means 300 to divide a guide line to a prescribed interval, a normal plane arithmetic means 400 to operate the normal plane orthogonal to the guide line concerning a point on the divided guide line, an interpolation curved line preparing means 500 to prepare the interpolation curved line on the normal plane and a sweep curved surface data storing means 600 to store the coordinates position of the interpolating point to constitute the prepared interpolation curved line in memory M as sweep curved surface creating data.
