Abstract
This paper presents a new method of optimizing manufacturing tolerances. On the principle of kinematics of the rigid body, we used transport matrices with polynomial functions. First, we did 1500 tests on a CNC machine to quantify the EBS deviations. By integrating the two matrices, force matrix and small displacement matrix, to determine manufacturing errors. An example of machining has been processed to validate the results.
Keywords: Optimization, modeling, manufacturing tolerances, errors.
