Claim of US Patent No. 10,990,078

1. A computer-implemented method having computer-executable instructions for performing part analytics of a workpiece machined by at least one CNC (Computer Numerical Control) machine, the method comprising:a. sending, to the at least one CNC machine, first instructions for machining the work piece under consideration, wherein the first instructions are based on a first digital model of the workpiece;
b. receiving, by a digital machine model of the CNC machine, realtime and non-realtime process data of the at least one CNC machine, the realtime and non-realtime process data having been recorded during the machining process, based on the first instructions, of the workpiece under consideration;
c. simulating the machining process under consideration by means of the digital machine model based at least partially on the recorded realtime and non-realtime process data;
d. identifying deviations between the simulated machining process and the first instructions;
e. generating, based on the identified deviations, second instructions for continued machining of the workpiece under consideration; and
f. sending, to the at least one CNC machine, the second instructions,
wherein the recorded realtime process data comprises a measured force experienced, during the machining process of the workpiece under consideration, by at least one part of the CNC machine, and
wherein the measured force comprises one or more of a measured bending force, a measured strain, a measured torque, a measured vibration, a measured pressure, or a measured torsion.
