Problems solved by technology
[0005] Although the toothed workpiece must be properly positioned relative to tools such as grinding wheels, the stock dispensing process can be time consuming
Typically, blank dispensing can take 15 to 20 seconds or more, which means that the machine (such as a grinding machine) is effectively idle because no actual machining is happening

A method wherein a first workpiece (2, 40) is loaded to a spindle (30) of a workpiece processing machine with the first toothed workpiece having a predetermined design and being in a predetermined rotational load position. The first toothed workpiece is stock- divided and a machining position is determined based on the stock-dividing. The first toothed workpiece is rotationally adjusted to the machining position. The teeth (3, 42) of the first toothed workpiece are then machined and the first workpiece is removed from the spindle. A second toothed workpiece is loaded to the spindle of the workpiece processing machine. The second toothed workpiece has the same predetermined design and is in the same predetermined rotational load position as the first toothed workpiece. The second toothed workpiece is rotationally adjusted from the predetermined rotational load position to the machining position by the same adjustment amount as the first toothed workpiece. The second toothed workpiece is machined and then removed from the machine spindle. The process as performed for the second toothed workpiece can be repeated for subsequent workpieces having the same design and being in the same rotational load position as the first and second workpieces. For the second and subsequent toothed workpieces, the step of determining the rotary position of the teeth is not carried out.
Description
technical field [0001] The present invention relates to gear manufacturing machines and methods, and in particular to the loading of workpieces onto a gear manufacturing machine followed by a blank dispensing step on the machine. Background technique [0002] In the production of toothed products, especially gear-shaped workpieces, such as bevel gears (such as pinion and ring gears) and cylindrical gears (such as spur gears and helical , forging, casting, etc.) followed by one or more finishing operations. Such finishing operations include, but are not limited to, grinding, honing, polishing, scraping, and finish cutting (eg, hard scraping, power scraping, etc.). [0003] Gear-shaped workpieces must be properly "stock-divided" (also known as centering, aligning, or phasing) before any finishing operations can be performed, which means that partially finished gears must be (for example, a roughing gear) the teeth are properly positioned relative to the tool before the finis...
