In industrial production is Zero Defect Management a current topic towards high requirements in manufacturing quality. An important industry application is the clamping system, which is essential in machining operation. The workpiece clamping system is the point of contact between workpiece and tool and due to that a crucial element for ensuring process reliability of the manufacturing process. The main difficulty in clamping process is to apply an appropriate force on a fragile workpiece, which has to be as much as necessary and as little as possible. This paper presents a novel actuator approach for a workpiece clamping system with the use of a solenoid considering pulse width modulated (PWM) voltage feed. The common usage for energization a solenoid is to apply alternating (AC) or direct current (DC). This common technique has just two switching states powered on and turned off. Therefore, this paper is proposing a special treated PWM signal, such that it is possible to control the magnetic field, and consequently the clamping forces, over an adjustable range of different power states. This approach allows to control the clamping force for holding the workpiece without physical displacement of the workpiece material. In this context the generated forces, with respect to the electromagnetic fields, powered by PWM signals, are evaluated with numerical simulations. The validation of the model is carried out through measurements to prove its accuracy.
