    Abstract
    This thesis presents the design and construction of a high-speed, four-way multipurpose machine capable of performing cutting with disc & hacksaw, drilling, and grinding operations simultaneously. The objective is to increase productivity, reduce operational costs, and conserve space and energy in small to medium scale industrial applications. The machine integrates multiple functions into a single system using a shaft-driven mechanism powered by a 2 HP motor, with power transmitted through pulleys and belts, including a Scotch-Yoke mechanism for the hacksaw operation. Real-time experimental tests were conducted on three commonly used materials: wood, aluminum, and mild steel. For wood, observed temperatures ranged from 32°C to 42°C during sawing, 32°C to 45°C during drilling, and 32°C to 102°C during grinding. For aluminum, temperatures ranged from 32°C to 42°C for sawing, 32°C to 40°C for drilling, and 32°C to 52°C for grinding. In the case of steel, temperature variations were noted as 32°C to 44°C during sawing, 32°C to 48°C during drilling, and 32°C to 60°C during grinding. These results validate the machine's functionality across a spectrum of materials and confirm its ability to operate under thermal stress within a manageable range. The proposed system proves to be a cost-effective, space-efficient, and versatile solution for industries requiring multi-operation capabilities, particularly where resource optimization is critical. The machine design holds potential for further enhancements such as speed regulation, tool change mechanisms, and automation features.
