Embodiment Construction

[0050] refer to Figure 1A as well as Figure 1B A processing device 20 (grinding machine) for grinding the side face of a gear cutting tool 2 for cutting a gear 1 using a grinding wheel 3 will be described. Figure 4 ). In the present embodiment, the processing device 20 is a tool grinder, an inclined wheel grinder, or the like. The processing device 20 includes a control device 40 . In addition, the control device 40 of the processing device 20 will be described later.

[0051] The machining device 20 includes a spindle unit 21 rotatably supporting the gear cutting tool 2 to be ground on a base not shown in the figure around a central axis X2 (θ22) of the gear cutting tool 2 . Moreover, the processing apparatus 20 is equipped with the grindstone 22 which supports the grindstone 3 so that rotation about the center axis|shaft X3 ((theta)3) of the grindstone 3 is possible. The control device 40 may be an embedded system such as a computer numerical control (CNC: Computer Nu...

Abstract

The invention provides a gear cutter machining apparatus and method, and a tool profile simulation apparatus and method. A controller (40) of a gear cutter machining apparatus (20) includes a rotationcontrol unit (41) and a movement control unit (42). The rotation control unit (41) rotates a gear cutter about a central axis (X2) of the gear cutter (2), and rotates a grinding wheel (3) about a central axis (X3) of the grinding wheel (3). The movement control unit (42) gradually changes a crossed axes angle (Eta) when relatively moving the grinding wheel (3) in a direction of the central axis (X2) of the gear cutter (2), and moves the grinding wheel (3) in a translating direction (M33) that is a rotational tangent direction of the gear cutter (2).

Description

technical field [0001] The invention relates to a processing device, a processing method, a tool shape simulation device and a tool shape simulation method of a gear cutting tool. Background technique [0002] A gear cutting tool for cutting a gear is formed in a shape based on the shape of a gear to be cut. Then, when the cutting edge of the gear cutting tool is worn, regrinding (hereinafter, simply referred to as "regrinding") is performed. For example, Japanese Patent No. 4763611 describes an invention related to the blade profile of a pinion cutter. This invention is a method of obtaining the error of the blade profile from the ideal blade shape when regrinding the pinion cutter. [0003] In addition, Japanese Patent No. 3080824 describes an invention related to regrinding of pinion cutters as gear cutting cutters. This invention is based on the ideal movement locus of the grinding wheel for grinding the pinion tool, that is, based on the movement locus of the grindin...
