Abstract
M.Ing.
A large number of machine tools in use today are worn and can not produce
the correct tolerances as a result of the inaccuracy of the structure. A device
was developed to assist in the solution to the problem.
The study of the development of this device includes several different fields. An
entire prototype scale model of a grinding device is developed, with
components including a control system and a developed sensor. The control
system consists of circuitry and programming. The programming has been
done in Visual Basic. The circuitry includes driver circuits for DC motors as well
as pulse width modulation circuits and filters, amplifiers and comparators for
the newly developed sensors. The sensor developed is an optical device, which
can sense the deviation of a cable for reference for the movement of the
device.
A combination of the above components into a unit and the provision for
factors, such as grinding forces and vibrations, which influence the operation of
the device, are presented. Furthermore, an analytical model is suggested for
the prediction of the system's behavior.
