Measuring strain during a cylindrical grinding process ...

2020-6-5  Abstract. This paper presents the results of using a sensor-integrated workpiece for in situ measurement ofstrain during an outer-diameter cylindrical grinding process. The motivation of this work is to measure in situprocess parameters using integrated sensors in a workpiece in order to characterize the manufacturing process.Resistive sensors that operate on the same principle as conventional strain gauges were fabricated on wafersmade of steel using standard micro and later the wafers were diced to form unique sensor-integratedsteel components (sensor inlays). These inlays are embedded into a groove on the top surface of a cylindricalworkpiece using epoxy adhesive. The workpiece is also made of the same steel as the sensor wafers and hassimilar properties due to a heat treatment process, thereby maintaining the homogeneity of the material over thewhole contact area. The sensor-integrated workpiece was used to perform experiments in a Studer S41 high-performance cylindrical grinding

Workholding for Cylindrical Grinding - Canadian

2011-8-16  The most widely used workholding method for cylindrical grinding is done between centers. Between-centers grinding does not require a centerless ground workpiece. In fact, many agree that the only way to create a perfectly round part from raw stock, in one setup, is to grind between centers. Many tool designers start with this methodology in mind.
