Abstract. This article investigates the manufacturing technology and quality assessment of an internal locking component used as a precision mechanical element. The study focuses on the structural and technological features of the component, material and blank selection, machining route development, quality control stages, and mathematical calculation of machining parameters. The main objective is to justify a systematic manufacturing approach that ensures dimensional accuracy, surface quality, functional reliability, and production efficiency. The research evaluates key indicators such as dimensional deviation, tolerance range, surface roughness, machining allowance, material utilization coefficient, cutting speed, feed rate, and machining time. The results show that the correct selection of structural steel, the use of a rolled blank, and the sequential organization of rough machining, precision machining, inspection, heat treatment, and final control contribute to improved component quality. The calculated values demonstrate that optimized machining parameters can reduce material and time consumption while improving dimensional stability and surface integrity. The proposed approach may be applied to the production of similar small-sized precision mechanical components.
