The traditional alignment method is that a lever dial indicator is firstly arranged on an alignment rod, then the alignment rod is arranged on a main shaft of a numerical control machining center through drill clamping, the main shaft is moved to the X0 point coordinate of a machine tool, an operator manually rotates the main shaft, the measuring head of the lever dial indicator can touch the angular hole wall of the part, and the hand wheel of the machine tool is operated to finely adjust the position of the rotating disc (C axis) of the machine tool continuously, so that the change of the pressure gauge value of the lever indicator is within 0.01 mm, then reading the mechanical coordinate value of the C axis on the machine tool, calculating the zero point coordinate of the C axis of the angular hole according to the drawing of the part, finally inputting the mechanical coordinate value of the C axis into the coordinate system of the machine tool, the whole process of the method is finished by an operator, the alignment efficiency and the alignment precision depend on the skill level of the operator seriously, meanwhile, an operator is easy to make mistakes when reading, calculating and inputting coordinate data, and the processing quality and the production efficiency of parts are influenced.

The alignment method has a complex process, an operator needs to repeatedly measure, calculate and correct the correction angle, the alignment efficiency of the method is not high, the alignment angular error range is less than 0.05mm, and the processing requirements of parts such as a case can not be met.
