*5.2. Workpiece Assessment*

The workpieces assessment was carried out prior to the grinding tests, that is, the workpiece mass was measured before the material removal caused by the grinding process. Thus, the data obtained shows the workpiece characteristics without material removal. After the grinding process (normalization and material removal), the workpieces were reweighed. Thus, it was possible to detect the mass variation of the workpiece machined by the grinding process. A precision scale with a scale of 500 g was used for this purpose. The workpieces were placed in the same position on the precision scale in order to avoid any changes that do not belong to the material removal caused by the grinding process.
