The correct way to measure concentricity on a grinding machine is 180º from wheel (back side), if the roll is supported on grinding seats. For example, if the grinding seat is out of round this form will be transferred to the roll shell by the grinding wheel. Run-out will not be seen on the wheel side but when a

Abstract. The article presents methodology for designing optimal feed control cycles resistant to unstable machining conditions for a batch of parts in round grinding operations performed on CNC machines. To improve the quality and reliability of control programs for CNC machines, a digital twin (DT) is proposed to be used.

A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.

A drilling machine, called a drill press, is used to cut holes into or through metal, wood, or other materials (Figure 4-1). Drilling machines use a drilling tool that has cutting edges at its point. This cutting tool is held in the drill press by a chuck or Morse taper and is rotated and fed into the work at variable speeds.

Working principle of Grinding Machine: The working principle of a grinding machine is quite easier to understand..
