【 摘 要 】

Nowadays, sampled-data interpolation algorithm has been the core technology in modern CNC system, so there are more researches concerning description of the principle of the arc-interpolation and presentation of the flowchart of the arc sampled-data interpolation algorithm. With the development of virtual simulation system software, the coordinate of arc-center is a key question inferred and confirmed by formulas. Therefore, the method of affine transformation is presented to transform the coordinates of the arc or the spiral curve. In addition, some major and minor arc, the clockwise and counterclockwise arc of quadrants, spiral curve along with these sampled-data interpolation algorithm software will be displayed in CNC virtual simulation system based on the visual C++.
