SFT method is applicable to the processing of spiral bevel gears with transmission ratio greater than 2.5, which means that the large wheel is processed by forming method and the small wheel is processed by knife inclination method. When machining large wheels by forming method, x, Y axes and...
The author verifies the proposed prediction method of strong tooth scraping on demaji nt5400dcg turning and milling machine. Among them, the cutting force of cylindrical gear scraping is measured by spike wireless sensor tool collet in Germany. The collet uses a plurality of strain gauges in different positions and...
CWE calculation is the most computationally intensive task in simulation. Therefore, in order to improve the simulation efficiency, this paper proposes to model only part of the workpiece, and estimate the cutting force of the whole process by superimposing the force required to cut a backlash. Some of the...
The two-dimensional chip shape is combined with the oblique cutting model to predict the cutting force at each time step. For each node related to chip shape, the force increment components ft, FF and fr generated in the tangential T, feed F and radial r directions can be expressed...
Equal height spiral bevel gear is widely used in automobile, aviation, aerospace and other fields because of its high transmission efficiency, strong bearing capacity, stable transmission and low noise. Machining equal height spiral bevel gears requires a lot of trial cutting, which is time-consuming and expensive. In this paper,...
1.Hardware structure of gear cutting system Hardware structure of gear cutting system: main control computer and main control system are two important parts. A bus integrated industrial control computer is selected as the main control computer, which has the advantages of rich software and hardware resources, strong anti-interference and...
NC machining of gears is an effective way to improve gear accuracy and machining efficiency. It is one of the main development trends of gear machining. The most commonly used gear machining method is continuous generation method, which is typically represented by gear hobbing, worm grinding wheel grinding and...
According to the cutting parameters of equal height spiral bevel gear determined by simulation and the inclined angle of cutter bar, the cutting test of equal height spiral bevel gear is carried out. The number of teeth of bevel gear is 10, the normal modulus MMN is 5.6mm and...
① Import the cutter bar and gear blank models established in UG into advancededge software according to the actual machining position (see Figure 1). Carbide general cemented carbide is selected as the material of the tool, and the minimum mesh size of the tool is set to 0.2mm; The...
