A method for cutting a PVC board based on a Mark point position function

A method for cutting a PVC board based on a Mark point position function features that an industrial camera is installed near that main axis of engraving and mil machine, and the relative deviation between the camera and the main axis is calculated by the function of biasing cutter of the camera. The engraving and milling machine formulates the strategy of searching Mark point according to the cutting procedure file; By searching Mark point strategy, four pairs of Mark point center coordinates and the current spindle coordinates fed back when the control board finds Mark point are obtained byindustrial camera respectively, and the coordinates of current camera coordinate system are converted into the coordinate system of cutting program file according to the Formosan rock; and the coordinate system of current camera coordinate system is converted into the coordinate system of cutting program file by industrial camera. The coordinates of the four converted Mark points are compared withthe coordinates of the Ma
