Abstract Surface polishing is one of the most conventional methods in the manufacturing process to reduce surface defects and friction of the workpiece. Drag polishing, which is used extensively for this aim, is one of the most well-known methods based on abrasive particles. Although this process is used extensively in the industry, it is problematic to identify the process parameters and their effects on the finished workpiece. In this work, the effect of the workpiece off-centering in the polishing container is studied using the discrete element model. In the first step, the numerical model is validated by the experimental result reported in the literature. Next, the effect of the workpiece position in the polishing container on the process attributes such as the kinematics of the particles and contact forces of the workpiece is surveyed, and the best position for maximum process efficiency is proposed.
