Description:TECHNICAL FIELD
[0001] The present disclosure relates to the field of wheels for commercial vehicles. In particular, the present disclosure relates to a method for manufacturing of a wheel for a commercial vehicle.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Traditionally manufacturing process for a commercial vehicle wheel includes producing a rim and a disc separately and then assembling the rim and disc by fitting the disc inside the rim followed by joining them by welding circumphereially. The conventional process of producing the disc includes the steps of blanking a sheet of steel, flow-forming the blanked portion, hub hole piercing, bolt hole piercing, vent hole piercing, and coining. Then, the rim and disc are assembled and welded followed by a notch milling process.
[0004] Notch milling is a process in which the material of the disc, rim, and weld materal is milled off in a radial direction extending from one of the vent holes for proper placement and access to the valve stem. Further, due to notch milling, sharp knife-like edges are formed that can cause injury to a user while accessing the valve stem. Besides, the notch milling process is relatively time consuming requiring setting up of the assembled wheel on a milling machine and thereafter milling operation.
[0005] Therefore, there is a need for a more efficient, cost-effective, and relatively safer method for manufacturing of a wheel for commercial vehicles.
