Abstract: A tool life prediction method according to the present disclosure comprises: allowing a target tool having a rake surface and a clearance surface to perform cutting under specific test conditions; obtaining three-dimensional shape data including the rake surface and the clearance surface of the target tool performing the cutting; calculating the wear volume from a difference between a first cross-sectional profile corresponding to the three-dimensional shape data and a second cross-sectional profile corresponding to shape data before processing; obtaining an immeasurable value in a tool wear volume calculation formula through simulation; deriving a plurality of constant values included in the tool wear volume calculation formula, based on the wear volume and the value obtained through the simulation; and predicting the wear volume of the tool by using the derived constant values.

Abstract: A method and system for certifying a low-carbon product using slaughter traceability information is disclosed. The method can be performed in a system for performing certification for a livestock product of a target subject, including obtaining reference carbon emission information which is information related to the average daily carbon emission of a reference group, by using slaughter traceability information of the reference group which is a group of the same livestock type of subjects as the target subject; deriving target carbon emission information which is information related to the amount of carbon emission per weight of the target subject, by using the slaughter traceability information of the target subject and the reference carbon emission information obtained in advance; and certifying the livestock product of the target subject as a low-carbon certified livestock product, when the value of the target carbon emission information decreases below a reference value.

Abstract: A method and system for reducing greenhouse gas using livestock genomic information is disclosed.
