Second, k-means algorithm is used to cluster quality data and extend the data base.
It enables intervention at an early stage within a specific machine as well as a reduction of defective parts during the production process.
Fourier Transform of Quality and Process Curves from Assembly Lines In general, data analysts doing data mining have too few data sets to generate reasonable and advanced information and dependencies.
Relating clustered quality data with assembly data provides insight in contributing factors of the assembly processes.
By applying this method on quality data from test benches, further information can be extracted from already existing data.

At the same time, for the expression (4) for the case of application of the solutions proposed in the work, in relation to the production of parts of the "Collector" type, there is a technological reserve for: - reduction of the error of the applied method of processing εmp due to the elimination of a number of machining and blade machining operations, - reduction of the error setting of the technological system of the machine εs due to the exclusion of a number of re-installations of the part, the use of normalized elements of technological equipment, the principle of unity and combination of technological bases, - reducing the error of the actual location of the workpiece details when it is installed in the device εl due to the exclusion of a number of resets of the part.
This leads to an increase in the number of components of the error, and according to (7) we obtain (8): εΣ1=kt∙εpm2+3Еi2+3Еb2+Еf2+Еa2+2Еdi22+εs≤ TА-(k⋅ TА)2 (8) Solution (8) is inequality εΣ1=0.325< 0.597, this indicates the accumulation of the total error at 50 % reduction of the specified accuracy of the size T under the specified conditions.

For example, single crystalline sheets of Ni3Al can be cold rolled to more than 99% reduction in thickness when the rolling direction (RD) is close to <100> [3].
Such irregular rolling deformation makes further reduction difficult.
The orthogonal components, , , and , were given from the widening and reduction of the rolled sheet and determined from the constant volume condition, respectively.
Among the three slip systems, the magnitude decreases in the order of a3, b1, and d1 until 30% reduction.
