Abstract: Drill bits are a common cutting tool in mechanics. The drill bit groove is a helical surface that requires grinding during the manufacturing process, as well as periodically during operation. This article focuses on the application of the orthogonal projection method in CATIA of the grinding wheel rotation axis onto the drill bit surface to find the contact line from which to create the grinding disc profile. The method is presented in detail, step by step, so that readers can repeat it in similar application cases. Additionally, the paper also aims to determine the optimal grinding disc placement parameters to prevent undercutting during machining, thereby increasing the machined area.
