The invention discloses a turning method suitable for part volume production and capable of offsetting shape errors. The turning method comprises the steps that (1) a first part in volume parts is subject to profile rough turning; (2) finish machining is carried out according to the theoretical profile; (3) two direction error amount, namely the finish machining error amount, of the part actual value and the final theoretical value of a detecting point is obtained; (4) a next similar part is replaced and installed, and the step (1) is executed; (5) the profile of the next part is subject to finish turning, and the finish machining error amount of the prior part is offset during finish machining; (6) the step (3) is repeatedly executed on the next similar part; and (7) each of the follow-up similar parts is treated according to the step (4) to the step (6), wherein the error compensation amount of the finish machining of the later part each time is the sum of the finish machining error amounts of all parts machined previously. By means of the method, shape errors, generated by factors of tool abrasion and the like, of parts machined in volume can be effectively reduced, and the part machining accuracy and production efficiency are improved.

The invention discloses a milling tooth machining parameter and path compensation method. The method comprises the following steps that S1, the installation error of the relative position of a tool and a workpiece is obtained, and the relative position between the tool and the workpiece after being installed is obtained by measuring the position of the tool and the workpiece, the installation error of the machine tool is obtained through subtracting the set relative position between the tool and the workpiece from the measured relative position; S2, the error of tool is obtained under action of cutting force and torque under action of cutting force by calculating; and S3, compensation is carried out on the machining parameters and the machining path, the set machining parameters are compensated through the error obtained in the step S1, and the compensated machining parameters are obtained; and the set machining path is compensated through the errors obtained in the step S1 and the step S2 so as to obtain the compensated machining path. According to the method, the machining errors are compensated, so that accurate machining of the gear is realized, and the precision of the workpiece is improved.
