Description
This process refers to the production activity of removing 1 kg of steel through fine turning machining. Fine turning primarily removes a small portion of the machining allowance from the surface of the workpiece, typically requiring high precision in product dimensions and surface roughness; therefore, smaller cutting depth and feed rate should be selected whenever possible. If the exact amount of steel removed during the fine turning process is not specified, an average assumption of "generating 0.124 kg of steel waste per 1 kg of final product" may be used. The data inventory is compiled from multiple data sources.
Activity Description
The dataset includes steel material inputs, direct electricity consumption of machinery, water consumption, lubricant consumption, and steel waste removed through machining processes, which is typically collected and reused.
Process Description
This process refers to the production activity of removing 1 kg of steel using a turning operation. Finishing turning mainly removes a small portion of the machining allowance from the surface of the workpiece, typically requiring high precision in product dimensions and surface roughness; thus, smaller cutting depth and feed rate should be selected whenever possible. If the amount of steel removed during the finishing turning process is not clearly known, an average assumption can be used: generating 1 kg of final product produces 0.124 kg of steel waste.

Technology comment
Turning is a machining technique in which the workpiece is fixed on the machine tool and driven by an electric motor to rotate at high speed, while the cutting tool fixed on the spindle moves across the surface of the workpiece for material removal. Throughout the process, only the workpiece rotates, while the cutting tool remains non-rotating.
