Form Relieved Milling Cutters are cam-relieved cutters and are sharpened by grinding the faces of the teeth. Form relieved milling cutters are used to mill curved surfaces, such as gear teeth profiles. These cutters are rotated at unusually high speeds to produce high performance screws at improved rates of production.
Formable coating is applied to the grooved lacquer replica, which covers the irregularities formed in the spiral groove. The metal stamper is free from the undesired irregularities covered over by the formable coating in the subsequent process.
Formaldehyde (HCHO) monitors are designed for measuring exposure to formaldehyde in chemical applications. It uses the scientific principle of diffusion, which is the gradual mixing of molecules of two or more substances. It is designed for health care, laboratory, chemical, pulp/paper, foundry and textile industries where formaldehyde is a major concern.
Formed coil is machine wound and insulated before it is installed in the slots of the stator core. The coil is sized so that it will span the distance between the poles of opposite polarity. A coil having this dimension is said to have full pitch. A coil smaller than this dimension is said to have fractional pitch. All of the coils of one single-phase winding are known as phase belt. The formed coils of a phase belt connected in series has the maximum voltage value.
