In the article a PC-based CNC machine control system is presented which communicates with servo drives and auxiliary input/output devices via EtherCAT bus. LinuxRTAI real-time operating system and LinuxCNC control software were implemented in the PC controller. A software module implementing EtherCAT communication with the servo drives was developed and integrated with LinuxCNC. Experimental results were presented which show the trajectory smoothing capabilities of the control system. Experimental results were also presented that show following errors obtained by running an example trajectory on a linear motion module. Basic parameters that show the control systems capabilities obtained during the experimental tests have been presented. The CNC control system presented in this article was implemented on a 3-axis machine.

Information communications networks, and especially their industrial versions (field networks), are an inseparable element of contemporary control systems. They enable pieces of modern industrial equipment to be coupled into a common system. In the case of older-generation equipment (universal one-stand CNC machine tools, manipulators, robots), their extension and integration in either dispersed or centralized control system is possible. As a result of modernization, it is possible to create a production line that will be built based on classic CNC machine tools and operated by manipulators or robots using network solutions and PC computers.

Abstract An important role among protective means play the elements of control systems performing safety functions. When the validation process of a safety performance level(PL) achieved by those systems is conducted properly one can draw the conclusion that any defect appearing in those systems would not cause the loss of safety functions. The paper presents formalized validation of the PL procedures for different categories and PL’s for introducing into the computer program which makes more efficient all the operations involved into the validation and documentation processes of safety performance level achieved by machine control systems.

Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point.Vibration platform uses machine, control system and information technologies to optimize human performance. In order to explore the mechanical effect of vibration based on machines and control systems on human performance, twenty participants were voluntarily involved in this trial. The findings of this study indicated that automation vibration has significant difference on human performance. It has a positive effect on human body. Therefore, vibration can be used in auto regulation.

The Impact

The paper presents a compensation system of thermal deformation for conventional feed axes applied in CNC machine tools allowing for an effective reduction in the impact of heat generated during its operation on the positioning accuracy of the axis. The result has been achieved by equipping feed screws with thermistor temperature sensors. Wiring sensors was led out through an axial bore in the screw and through a rotating electrical connector to an acquisition device coupled with the control system of the CNC machine. An algorithm based on neural networks was implemented in the machine control system, which allows for the online calculation and compensation of heat deformation of feed screws. The algorithm takes into account a variation of thermal deformation values as a function of the table position and the current distribution of the temperature field of the screw and machine. The paper presents a user-friendly method for implementing algorithms containing neural networks in the machine control system. The proposed compensation method has been verified by measuring the linear accuracy of the feed axis positioning. The obtained results confirm the effectiveness of the proposed method in reducing the impact of thermal deformation errors on the positioning accuracy of the axis in CNC machine tools.

Important Design

The stiffness of cable flight control systems is one of the most important design parameter for aviation aircraft, because it can change the characteristic of control stick and influence the maneuverability and stability of the flight control system. Flexible cable control system is the main type of mechanical flight control system, in which movement can only be transmitted by cable in tension, the stiffness of cable control system is affected mainly by predetermined preload(PP), however the excessive PP would increase friction between cable and pulley which leads pilot an unfavorable maneuver. In this paper, the theoretical stiffness calculation of cable control system with the complex cable braided construction has been calculated and discussed, in addition the effects of cable deflection and linkage pulley are taken into account to obtain a precise stiffness calculation, and also the predetermined preload related to friction is studied through numerical example, as well as the numerical results have been compared with the experimental results.

The development of a microcontroller system in the control system more advanced, more and enable people to perform the control of a device automatically without a computer device. This makes the control systems in various industries increasingly easy and cheap. In this study will be made of plastic cutting machine control system roll sensor-based optocoupler. This tool uses two dc motors, one as a driver to roll up the plastic so that the plastic to form a roll (a roll), and other dc motor to move the heater (seal) and cutter. For the heating process (seals) used a wire niklin while cutting process using a saw blade. Untukmenentukan long pieces of plastic then used an optocoupler sensor and microcontroller ATmega16 as the main control center.Kata kunci : Mikrokontroller AT Mega 8535
