Abstract
A method for grinding bevel gears (1), wherein a first grinding tool (2) is used during a first method section and a second grinding tool is used during a second method section. A measurement system (30) is used to carry out a measuring procedure, in which sampling values can be ascertained for at least a part of first flanks of the bevel gear workpiece (1), which enable a statement about the concentricity error of this bevel gear workpiece (1) in the present chucking. Concentricity correction dimensions are ascertained by computer on the basis of the sampling values, and an adaptation of machining movements of the second method section is performed on the basis of the concentricity correction dimensions.
Claims14
A method for grinding bevel gears comprising:
- a) fastening a first grinding tool on a tool spindle of a grinding machine,
- b) fastening a first workpiece on a workpiece spindle of the grinding machine,
- c) performing a CNC-controlled first single-indexing grinding procedure using the first grinding tool, wherein all first tooth flanks of the first workpiece are machined by grinding step-by-step during said first single-indexing grinding procedure,
- d) separating the first workpiece from the workpiece spindle,
- e) at a later point in time, re-chucking the first workpiece on the workpiece spindle of the grinding machine, which carries a second grinding tool on the tool spindle,
- f) performing a measurement procedure using a sensor of the grinding machine to obtain sampling values at least for a part of the first tooth flanks, and determining a concentricity error of the first workpiece After said re-chucking,
- g) determining concentricity correction dimensions using a computer, and
- h) performing a CNC-controlled second single-indexing grinding procedure using the second grinding tool, wherein all second tooth flanks of the first workpiece are machined by grinding step-by-step during said second single-indexing grinding procedure, and executing machining movements during the second single-indexing grinding procedure based on said concentricity correction dimensions.
