Problems solved by technology

After the tooth milling process is assisted by ultrasonic vibration, the cutting parameters can be changed according to the requirements of rough and finish machining, and the processing efficiency, surface quality and tooth profile accuracy can be further improved. The machining error caused by it is difficult to control, and the existing error compensation method is difficult to accurately compensate the comprehensive machining error under complex conditions, which cannot meet the requirements of precision machining, and is not suitable for ultrasonic vibration-assisted milling.

Embodiment Construction

[0045] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0046] A tooth milling processing parameter and path compensation method of the present invention includes steps S1, S2, and S3.

[0047] S1: Obtain the installation error of the relative position between the milling tool and the workpiece, obtain the relative position of the tool and the workpiece after installation by measuring the positions of the milling tool and the workpiece, and subtract the relative position set by the tool from the measured relative position to obtain the machine tool The installation error; specifically, after installing the milling tool, the actual relative position of the tool and the workpiece P t -P w Relative to the ideal position P t '-P w 'like figure 1 shown. The ideal relative position of the tool and the workpiece can be obtained by decrypting the program code of the gear milling machine tool. The actual rela...

Abstract

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.

Description

technical field [0001] The invention relates to the field of machining, in particular to a milling gear processing parameter and a path compensation method. Background technique [0002] At present, tooth milling is an effective method for processing gears, such as figure 2 The workpiece is machined as shown. Compared with traditional processing technology, ultrasonic vibration assisted processing has the advantages of smaller cutting force, lower tool wear, better workpiece surface quality and higher cutting efficiency during processing. After the tooth milling process is assisted by ultrasonic vibration, the cutting parameters can be changed according to the requirements of rough and finish machining, and the processing efficiency, surface quality and tooth profile accuracy can be further improved. The machining error caused by it is difficult to control, and the existing error compensation method is difficult to accurately compensate the comprehensive machining error un...
