Embodiment Construction

[0018] The present invention will be preferably described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as Figure 1-3 As shown, an embodiment of the method for determining the depth of cut of gear machining in the present invention includes the following steps:

[0020] The first step is to calculate the total area S of the gear to be removed;

[0021] The second step is to calculate the total area Sh of the gear blank to be removed when the difference between the cumulative cutting depth and the standard depth H is h; for example, after a gear parameter is determined, the full tooth depth of the gear is the standard depth H to be cut, and the cutting depth refers to the actual The depth of cutting is required each time during the cutting process, because a larger gear will not cut to the standard depth H at one time, and it needs to be cut several times. If the standard depth H=9cm, cut twice, the first cut is 6cm deep, that is...

Abstract

The invention discloses a method for determining the gear machining cutting depth. The method comprises the following steps that (1) the total area S needing to be cut off of a to-be-machined gear iscalculated; (2) the total area Sh of the removed gear blank is calculated when the difference between the accumulated cutting depth and the standard depth H is h; and (3) the cutting depth tn of eachtime of feeding is calculated according to the machining cycle index n. According to the method, the area of the groove part needing to be cut of the gear blank at any cutting depth is calculated; ifthe gear is machined in several times, the gear is machined; each cutting area can be equal through calculation, so that the overall cutting stress of the cutter in each cutting process is relativelyconsistent, the conditions of large first cutting amount and small second cutting amount do not exist, the cutting depth is automatically distributed in the machine tool, unreasonable manual setting is prevented, the service life of the cutter is ensured, and the machining efficiency and precision are improved.

Description

technical field [0001] The invention relates to a method for determining the cutting depth of gear machining, in particular to a calculation method for calculating different cutting depths when a gear shaping machine processes large-module gears, and belongs to the field of mechanical processing. Background technique [0002] At present, in the gear shaping process of the gear blank, the tooth shape will be cut out multiple times according to the modulus of the gear. However, the cutting depth of each feeding during the reciprocating cycle of the cutter shaft is generally set according to experience. The distribution is not reasonable enough, so that the cutting force of the tool changes greatly in each feed, causing damage to the machine tool and reducing the tool life. At the same time, setting too many cycles will reduce the machining efficiency of the machine tool and increase the machining cost. Contents of the invention [0003] The purpose of the invention is to so...
