Comentário geral sobre o conjunto de dados This dataset covers all relevant input and output flows of the represented gate-to-gate unit process. The inventory is mainly based on industry data and, where necessary, complemented by secondary data. The reference flow is 1s of manufacturing processing time, and all inputs and outputs are normalized for each second of the machine operation. The inventory flows were parametrized for the different operation modes (start up, stand by, full load and shut down) of the machine tool.

Representatividade tecnológica
Descrição da tecnologia, incluindo sistema de fundo Current technology using for the machining process. The process has high automation level, and the values ​​for the inputs and outputs were calculated as the average values between two machining centers that were studied. The first one is a machine tool built in 2011 and the second one is a 2018's technology. Both machining centers were studied in four modes of operation: Startup (the equipment is warming-up waiting for the machining cycle to start, but no operation is taking place); Standby (the equipment has completed a machining cycle and is waiting for the removal of the finished product and insertion of the raw material to start a new cycle); Full load (the equipment is performing the machining, chip is being removed; Shut down (the equipment has finished the day production demand and will be shut down). During the production cycle in full load mode different machining methods are performed. The machining methods performed by the machining centers are: Milling, Boring, Drilling; Threading. Also, the subunits of the machining centers covered are: Primary system (lighting, computers and sensors start-up, hydraulic unit); Spindle; Toolholder; Refrigeration system; Exhaust system; and Chip conveyor.

gd_price_waste 0.5 % This parameter was added by GreenDelta during the implementation of the ecoinvent database in openLCA. It is used by those exchanges which did not have a price specified by ecoinvent for being wastes (i.e. negative reference product), and that were considered that they should have a cost/revenue specified. The prices used for them, equal to the prices of the same product in other processes of the database, are modified by this parameter with value 0.5 (i.e. half the price of the normal product), considering that the reference product of a waste treatment process might have a lower price in reality than the same flow produced by a production process. However, you can modify this value to 0 if you prefer to consider no price for them like ecoinvent, or also 1 if you do not want to distinguish wastes from other products.
gd_price_product 1.0 % This parameter was added by GreenDelta during the implementation of the ecoinvent database in openLCA. It is used by those exchanges which did not have a price specified by ecoinvent and that were considered to be products or co-products of waste treatments (i.e. positive reference product), and that they should have a cost/revenue specified. The prices used for them, equal to the prices of the same product in other processes of the database, are modified by this parameter with value 1. However, you can modify this value to 0 if you prefer to consider no price for them like ecoinvent.
ei_price_product 1.0 % This parameter was added by GreenDelta during the implementation of the ecoinvent database in openLCA. It is used by those exchanges which did not have a price specified by ecoinvent in this specific system model, but yes in at least one of the other two system models. The prices used for them, equal to the prices of the same product and provider in the other system model, are modified by this parameter with value 1. However, you can modify this value to 0 if you prefer to consider no price for them in this system model like ecoinvent.

Seleção de dados e princípios de combinação Primary data were collected for the machining production system. See 'Geography' and 'Technology' scopes for more details.
Desvio da seleção de dados e princípios/explicações de combinação None.
Princípios de tratamento de dados e extrapolações All the input/output data were converted to the functional unit of 1s of manufacturing operation by using the UPLCI methodology developed by Kellens et al. (2012a,b). All the collected input/output flows followed the "in-depth assessment" approach proposed by the UPLCI methodology.
