Description
This dataset represents the process of removing 1 kg of steel through turning operations. The life cycle inventory is compiled from data collected during the production of pneumatic triple-offset high-performance butterfly valves, hard-sealed butterfly valves, specialized ash-discharging ball valves, ultra-compact ball valves, and other butterfly and ball valves. The dataset includes the main raw and auxiliary materials, energy inputs, and metal waste removed during the turning process, which is typically collected and recycled for reuse. Infrastructure such as manufacturing equipment and facility construction is excluded from the system boundary of this dataset. Lathe machining is a mechanical machining technique where the workpiece is secured on the machine tool and rotated at high speed by an electric motor. At the same time, the lathe tool fixed on the spindle is controlled to cut and shape the surface of the workpiece. Throughout the process, only the workpiece rotates, while the cutting tool remains non-rotating.
Activity Description
Lathe machining is a mechanical processing technique where the workpiece is fixed on the machine tool and rotates at high speed driven by an electric motor, while the cutting tool, mounted on the spindle, is controlled to cut and shape the surface of the workpiece.
Process Description
This process refers to the production activity of removing 1 kg of metal using turning operations during the manufacturing of butterfly valves and ball valves. If the weight of metal removed in the turning process is not explicitly known, an average assumption of "0.162 kg of metal waste generated per 1 kg of final product" can be used.
