Abstract
In a method for machining bores of workpieces with a desired nominal shape of the bores in operative condition, a bore with a desired nominal shape in inoperative condition is produced in a workpiece and the workpiece is then put in operative condition. A deviation of the desired nominal shape of the bore resulting from the operative conditions is determined. Based on the deviation, an initial shape which shape the bore must have in inoperative condition in order for the bore to assume the desired nominal shape in operative condition is the determined. Bores are then produced by employing the determined initial shape as a template.

A method for machining bores of workpieces with a desired nominal shape of the bores in operative condition, the method comprising the steps of:
- a) producing in a workpiece a bore with a desired nominal shape in inoperative condition;
- b) putting the workpiece in operative condition;
- c) determining a deviation of a shape of the bore resulting from step b) from the desired nominal shape of step a);
- d) determining from the deviation of step c) an initial shape which shape the bore must have in inoperative condition in order for the bore to assume the desired nominal shape in operative condition;
- e) producing bores by employing the initial shape of step d) as a template.
The method according to clean 4, wherein in the step b) static pressing is employed and the obtained geometry is measured to determine the deviation.
