Problems solved by technology

However, the existing processing methods are difficult to control due to the relatively complex relative motion in the hobbing process and the resulting processing errors, and the existing error compensation methods are difficult to accurately compensate for the comprehensive processing errors under complex conditions, and cannot meet the requirements of precision processing. Suitable for ultrasonic vibration assisted hobbing

Embodiment Construction

[0046] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0047] A hobbing processing parameter and path compensation method for efficiently processing face gears of the present invention includes steps S1, S2, and S3.

[0048] S1: Obtain the installation error of the relative position between the hobbing tool and the workpiece, obtain the relative position of the tool and the workpiece after installation by measuring the positions of the hobbing tool and the workpiece, subtract the relative position set by the tool and the workpiece from the measured relative position, and obtain the machine tool The installation error; specifically, after installing the hob cutter, the actual relative position between the cutter and the workpiece P t -P w Relative to the ideal position P t '-P w 'Such as figure 1 shown. The ideal relative position of the tool and the workpiece can be obtained by deciphering the progr...

Abstract

The invention discloses a gear hobbing processing parameter for efficiently processing a face gear and a path compensation method. The path compensation method comprises the steps of (S1) obtaining the installation error of the relative position of a cutter and a workpiece, obtaining the relative position of the cutter and the workpiece which are installed by measuring the position of the cutter and the workpiece, and subtracting the set relative position of the cutter and the cutter from the measured relative position so as to obtain the installation error of a machine tool; (S2) obtaining the error of the cutter under the action of cutting force and centrifugal force and torque through calculation; and (S3) compensating the processing parameter and a processing path: compensating the setprocessing parameter according to the error obtained in the step (S1) so as to obtain the compensated processing parameter, and compensating the set processing path according to the errors obtained in the steps (S1) and (S2) so as to obtained the compensated processing path. According to the gear hobbing processing parameter and the path compensation method, the processing error is compensated, so that the gear is accurately processed, and the precision of the workpiece is increased.

Description

technical field [0001] The invention relates to the field of machining, in particular to a hobbing processing parameter and a path compensation method for efficiently processing face gears. Background technique [0002] At present, face hobbing is an effective method for processing gears, such as figure 2 As shown, the inner gear cutter and the outer gear cutter are installed on the cutter head. During the relative movement between the tool and the workpiece for processing one tooth, the inner gear cutter processes the inner tooth profile of the tooth, and the outer gear cutter processes the outer tooth profile of the tooth. The continuous processing of forming teeth has been widely used in the processing of various bevel gears. 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 ultr...
