For example, an angle grinder used as a cutting tool is just one disc change away from being a sanding tool, or a paint removal solution.
A number of diverse methods can be used for gathering evidence to identify the mechanisms of abrasive-workpiece interactions. One possibility is to examine the grinding debris (swarf) produced by the process in order to theorize how it could have been produced. For this purpose, the scanning electron microscope (SEM) is an invaluable tool.

The cylindrical grinding machine used to measure the current signals of the spindle motor by using a hall sensor has a 3.7 kW power spindle motor and 1710 rpm grinding wheel rotation speed. Fig. 3 shows the schema of the experimental set-up. Before each grinding experiment, the dressing was performed to the depth of 0.02 mm.
The basic principle behind the working of an electric motor is the action of electromagnetic forces. When a wire carries an electric current and is placed in a magnetic field (e.g. near a magnet), it feels a force that pushes it in a certain direction – depending on the orientation of wire and magnetic poles.. The body of a motor is made of two main parts; static part and rotating part.
