Use of Mechatronic System to Manufacture Spiral Bevel Gear

using 3-Axis CNC Milling Machine

Spiral Bevel Gear

 : Abstract
Gears are crucial components for modern precision machinery as a means for the power transmission mechanism. Due to their complexity and unique characteristics, gears have been designed and manufactured by a special type of machine tools, such as gear hobbing and shaping machines. The spiral bevel gears (SBG) are the most complex type and are used to transmit the rotational motion between angularly crossed shafts. In this paper, we attempt to manufacture the spiral bevel gear by a three-axis CNC milling machine interfaced with an additional PLC module. This consists of (a) Geometric modeling of the spiral bevel gear. (b) Simulating the traditional and our new non-traditional method using a CAD/CAE system. (c) Process planning for CNC machining and PLC programming. Experimental cuts were made to discover the validity of the presented method with a three-axis CNC milling machine
