Abstract
Rolling machines are often used for forming flat elements or pipes. Problems occur when used to produce cylindrical elements other than pipes, or when experimental materials are used. It is required to introduce flexible control of the rolling process parameters in such cases. It is necessary to monitor the device operating parameters. When a rolling machine works with experimental materials, there are no typical control and acquisition data systems available. The article presents the concept and capabilities of the control and computer data acquisition system supporting the rolling process. The main task of software system is acquisition of force and kinetic parameters related to the analysed process of the compression during rolling. This system allows current recording and analysis of five physical values. The acquisition data application is developed in National Instruments LabVIEW environment. The software algorithm is based on the state machine. The article contains a detailed description of hardware and software implementation of the functions mentioned.

Optimum parameters of the rolling process are determined on an experimental basis and on the basis of employees’ experience
Summary
The machining process is widely used in the metallurgical industry. The rolling process is characterised by low machining time, low material losses and resulting low production costs. Attempts to connect individual rolling parameters have been carried out selectively. One of the research directions is an attempt to develop numerical models of the rolling process. Attempts were initiated at the end of the 20th century and are carried out to this day [8, 9] Such models are available in commercial applications, and the accuracy of the selected model is a new problem [10]. It is required to have a test bench equipped with the possibility of modifying the rolling parameters (speed of tools, strength) – Fig. 1. It is necessary to collect data on all key process parameters in a way that is convenient for the researcher. The system is based on a single source: the budget USB-6008 measuring card programmed in the LabVIEW environment
