Abstract: The paper describes basic characteristics of pneumatic artificial muscles (PAM) for using as actuator in mechatronic system. The previous parameters research of individually connected artificial muscles shows, that it is significantly nonlinear system with time delay. Availing these results, problem of using of static and dynamic characteristics of PAMs for control and modeling electropneumatic mechatronic systems based on the artificial muscles occurs. To solve this problems, the paper also deals with design of some models.

Abstract: The aim of the contribution is to describe modelling of selected reliability indicators of prototype equipment with PAM. Purpose of model is maximizing overall equipment reliability by the means of optimal selection of basic elements or by proper redundancy of the elements. Further, possibilities of reliability increase by the means of active and passive reserve are described, as a higher level of reliability control in given technical equipment with PAM. Summary of particular ways of reliability increase is presented on an example of a given prototype mechatronic equipment based on artificial muscle.

Abstract: The article studies, based on the evaluation of the experimental research, effectiveness of independent and combined interaction of selected methods when diagnosing bearing of the mechatronic device in course of 6 months. During this time the general overhaul of the device was carried out, where the measurements, analyses and evaluations were focused on run-in and a shorter after run-in period of the bearing.

Abstract: Innovation of the technological processes is a very important part of continuous improvement of each manufacturing company. Every manufacturing company is trying to optimize the production processes to achieve the improvement of basic indicators, which include price, quality and speed of the production process. One of the means to achieve these indicators is to optimize the cutting parameters, which ensure the desired quality of the surface in a shorter manufacturing time. Innovation of the technological parameters of the manufacturing company means to repair, improve, and transform these parameters, which are used and show loss limitations. Application of updated parameters for manufacturing company may refer to significant reduction of engineering times, improving the material flow and the other factors, but it is mainly costs saving. This article is specialized on the study of the surface quality of the material AISI 304 by turning technology with selected cutting tool of sintered carbide. This material is usable for actuator (actuators and reduction gears) too.
