The aim of the article is to present the essence of the adaptation of common SPC solutions appropriate for mass and batch production, to the conditions of piece and small lot production on the example of the selected production process. The article presents the possibility of using Shewhart control charts in improving piece and small lot production processes. The principles of data collection and transformation, to be useful to prepare charts, have been pointed out. Moreover, determination of capability indices for piece and small lot production has been shown. The proposed solution of using statistical process control tools in the analyzed company enables the board a fair assessment of the processes from the point of view of quality assurance, and thus reduce the cost of poor quality and well targeted improvement actions.

The paper describes a general concept of using a 3D scanner in production conditions, as an alternative to inspection and test devices. The tested object was a body of HCVB6 high-pressure valve. The input from the test object is a cloud of points acquired from the scanning of the valve body and a virtual 3D model. Comparing the virtual model with the factual itemprovided conditions to perform control and measurement analysis. The paper contains measurement results of the valve body obtained with Atos scanner manufactured by GOM company and "GOM Inspect" software. The concept of 3D scanning in production conditionsshows the advantages and disadvantages of the control and measurement process.
