Industrial enterprises are responsible for increasing production waste. The purpose of the research is to develop tools of material resources management in lean production for sheet metal cutting at engineering enterprises with single or serial types of production. At the previous stages of the research, a situational analysis of the cutting process was conducted, a literature review was carried out, and the main provisions of the sorting method of sheet metal material resources after cutting were defined for dividing them into groups of business or non-business material resources. The main provisions of the proposed method are specified in this article. Further research tasks are also identified.
