The invention belongs to the field of metal cutting and processing devices, and particularly relates to a shooting system used for high speed imaging in orthogonal turning and milling processes. A special milling workpiece or a special slotting knife for installation and clamping of a lathe tool installation clamp is arranged on the bottom of an observation device for turning and milling, and by cooperating with a vertically set special turning workpiece or a special straight blade milling knife, the turning and milling processes can be finished. A light reflection mirror with the surface plated with silver is installed on the slope of one side of a substrate. A high speed camera is arranged on the opposite side of the light reflection mirror with the surface plated with silver. A laser light source is arranged between the turning and milling device and the high speed camera. The high speed camera records the turning and milling processes. According to the invention, by use of sapphire glass, turnings and the workpiece are limited to be in the same plane, so a problem that turnings are unclearly shot caused by small field depth of the camera in the mesoscopic scale is solved; by use of the observation device for turning and milling, conversion in shooting of turning and milling can be performed only by changing few parts; the device is simple to assemble; the quality of the shot pictures is stable; and the shooting system is highly practical.
