The puncher uses locally sourced materials to deliver an effective solution which small-scale silkworm producers can easily access. The machine assessment used three measurements which included cut precision and cutting efficiency and cost-return analysis. The puncher provides an efficient method for preparing silkworm feed through its integration of new mechanical technologies with traditional agricultural methods which enhance productivity while reducing operational expenses.enThesis
