The interface of the gear shaper includes the most basic parameter information such as the number of teeth, modulus, internal and external teeth, and then the cycle times of gear processing, that is, the number of tool jumps, are determined according to the full tooth depth of the gear. Generally, 1 ~ 2 cycles are added when the full tooth depth is within 5mm
If the full tooth depth is 5 ~ 10mm, 3 ~ 5 cycles are adopted. The maximum cutting area of a single cycle of the machine tool is determined by the design power of the machine tool. For details, please refer to the operation manual of the machine tool.The cutting mode of gear shaper is intermittent cutting, the tool bears impact force, and the unreasonable recommendation of feed depth leads to great change of cutting force of the tool, rapid tool wear, and direct damage to the tool in serious cases. At the same time, when the feed depth setting is unreasonable, the cutting noise of the machine tool increases and the vibration is obvious, which affects the service life of the machine tool. Therefore, users need to comprehensively consider and count various factors of the machine tool, such as the durability of on-site tools, gear machining accuracy, machining efficiency and the noise or vibration of the cutting state of the machine tool, and finally select a reasonable parameter setting, which takes a long time.
Nowadays, with the development of automation and intelligence in industrial technology, the reasonable selection of cutting parameters is of great significance to machine tools. Whether it is appropriate or not directly affects the processing quality, production efficiency and processing cost of products. Through the analysis of the cutting process of gear shaper, the calculation formula of the blank area removed by the tool at different cutting depths is deduced, It ensures that the total area of gear blank removed by the machine tool under different feed cutting depths is equal, so as to achieve the purpose of consistent total cutting force of the machine tool in each cycle. The theoretical calculation can be applied to the NC system of the machine tool. It has a certain intelligence for the selection of cutting parameters of the gear shaper and guides the reasonable selection of cutting parameters.
