Pneumatic elements of machines tools

In this manuscript, pneumatic actuators working as subassemblies and assemblies of machines tools with precise adjustment of parameters such as force or displacement which have been tested. Currently, modern manufacturing technologies often use machines tools equipped with programmable logic controller (PLC) and regulators. The process of regulation itself is a well-known topic. The case became more complicated if there is a need to obtain the components position using compressed air. The adjustment of the position of the rodless double-acting pneumatic cylinders with the use of proportional-integral-derivative controller (PID) controller and visualization was subjected to a detailed analysis. Pneumatics is a field of technology dealing with the use of gases (usually air) as a medium transferring energy or information. Due to the type of medium, the problem of exact positioning causes a lot of trouble, because the gases structure is treated as compressible liquids. For the exact positioning of pneumatic drives, various types of position sensors or regulators are used to determine the position with high accurately. The mere application of the regulator does not change the operation of the system, however, it should be properly configured and the appropriate settings should be made. The main purpose was to carry out tests for measuring the position of the pneumatic rodless actuator, using a proportional valve, PLC Siemens S7-1200 controller and the computer program “TIA Portal”.
