Abstract
The aim of this paper is the issue of a sustainable manufacturing process in the context of woodworking by sanding, as one of the most important technological operations before its final treatment, focusing on a selected pillar of sustainable manufacturing process, waste management. The first step of the experiment was to optimize the pressures of the sanding means on the surface. The optimal pressure of 1.04 N·cm−2 was chosen. The second level was to obtain the wear curves of the abrasive means with grain size 80 (evaluated by wood removal) and the optimal pressure in dependence on the sanding direction (along and perpendicular to the wood fibres and in the direction of 60° to the wood fibres) and different types of woods (beech, oak, alder, pine). The set parameters were suitable for beech and were not suitable for alder and pine. By extending the operating life of the sanding belts via appropriate choice of input factor settings it can be influenced metrics of pillar waste management-savings of material and waste minimization.

The wood sanding process is one of the technologies that significantly affects the resulting quality of the wood surface, to which the quality of the product itself is related. In terms of the final effect, it is a technology that will affect the number of coatings applied, the operational life of the surface film, etc., as sanding is the last processing operation before the surface-finishing treatment. Due attention is not paid to the issue of a sustainable manufacturing process and the upper management of the companies does not often consider its solution as urgent because, in society, the view remains that it is an issue that primarily affects the environment [12,13]. The concept of sustainable development or sustainability is a notion that was defined in the
