Manufacturing straight bevel gears
View Patent ↗A method and tool arrangement for producing straight bevel gears and the like on a multi-axis computer controlled machine wherein a single tool is utilized in the machining process.
1. A method of machining bevel gears on a multi-axis free-form gear generating machine, said method comprising:
providing axes settings from a first machine comprising first and second tools each having stock removing surfaces, said first and second tool each being positioned in an inclined manner in said first machine whereby upon rotation during machining an interlocking arrangement of the stock removing surfaces of the first and second tools is formed to machine a tooth slot,
transforming axes settings of the first inclined tool of said first machine to axes settings of a basic gear generating machine,
transforming said axes settings of said basic gear generating machine to the axes settings of said multi-axis free-form gear generating machine,
machining a first portion of a tooth slot in a workpiece on said multi-axis free-form machine, said machining being carried out with a tool having the form of one of said first and second tools.
2. The method of claim 1 further comprising:
transforming axes settings of said second inclined tool of said first machine to axes settings of a basic gear generating machine,
transforming said axes settings of said basic gear generating machine to the axes settings of said multi-axis free-form gear generating machine,
machining a remaining portion of said tooth slot in a workpiece, said machining of said remaining portion being carried out with said tool having the form of one of said first and second tools.
3. The method of claim 2 wherein said first portion of all tooth slots in said workpiece are machined followed by machining of said remaining portion of all tooth slots of said workpiece.
4. The method of claim 1 wherein said tool having the form of one of said first and second tools and said workpiece are moved relative to one another in a manner wherein said tool having the form of one of said first and second tools is fed into said workpiece along a vector path.
5. The method of claim 1 wherein said tool having the form of one of said first and second tools is a cutting tool.
6. The method of claim 1 wherein said tool having the form of one of said first and second tools is a grinding wheel.
