According to the construction theory of the straight surface, a straight surface can be constructed by giving the trajectory of the upper and lower harmonic three-dimensional cutting harmonics FHA-8C-100-E200-CE, curve endpoints and path parameters. When the curve arc length is taken as the distance parameter, the constructed straight surface is natural straight surfac

3d straight surface machining can be realized by using a common 2d linear cutting machine tool and a NC rotary table accessory. The workpiece is mounted on a rotary work table driven by a stepping motor, and programmed by numerical control movement and numerical control rotation, the machining of straight surface can be completed
