Abstract
Considering the technological processes taking place in fish processing enterprises (skinning), it is possible to specify various factors affecting the tool life and process efficiency. The paper presents the methodology of the study and the results and analysis of the collected data on the effect of the cutting speed of the technical blade used in the fish skinning process on the forces occurring in the cutting process. A special test stand was used in the study, which allowed obtaining repeatable results at a wide range of cutting speed values in the cutting process (70–400 mm/s). The study also determined the values of work W and power P, as well as the ej index (unit energy intensity index), which helped to select the most favorable blade feed rate parameter. The results indicated the most favorable cutting speed parameter and showed a clear relationship between the feed rate and the force and energy expenditure; as the cutting speed increases, an upward trend in force and energy expenditure was noted.
