First Claim
Patent Images
1. A method for compensating for at least one of positional deviations and shape deviations in NC-controlled cutting production machines having an NC program, the method having the following steps:
- a) securing a new workpiece;
b) processing the workpiece using nominal data of the NC program, wherein the nominal data includes design values of the workpiece;
c) acquiring set deviation data which is based on differences between the nominal data and measured values of the workpiece;
d) optimizing the NC program using the acquired set deviation data; and
e) repeating steps a) to d) until at least one of required positional and shape tolerances have been achieved.

2. A method for compensating for positional and shape deviations in NC-controlled cutting production machines having an NC program, the method having the following steps:
-
a) preparing a workpiece in which an allowance is greater than at least one of a maximum positional deviation and a shape deviation that is to be expected; b) acquiring set deviation data which is based on differences between design values and measured values of the workpiece; c) optimizing the NC program using the acquired set deviation data; and d) finishing of the workpiece using a modified NC program.

3. An NC-controlled cutting production machine having a device for compensating at least one of positional deviations and shape deviations in workpieces, the device comprising:
- a control unit that has a storage unit for storing a target geometry of a workpiece, a measurement device for acquiring an actual geometry of the workpiece, and a computing unit for calculating set deviation data based on at least one difference between the target geometry and the actual geometry of the workpiece where the computing unit automatically optimizes an NC program corresponding to the set deviation data.
