Claim 6:
7. A lubricating oil volume adjustment method, suitable for adjusting a lubricating oil volume used by a machine during operation through an electronic device, and the lubricating oil volume adjustment method comprises:
acquiring current information of present operation of a motor of the machine;
predicting a temperature value of the machine when the motor operates under the current information by using a machine learning model, wherein the machine learning model is trained by a training data set comprising a plurality of pieces of the current information of the motor during operation and a plurality of temperature values measured during operation of the machine; and
calculating and adjusting the lubricating oil volume suitable to be used by the machine during operation according to the predicted temperature value, comprising:
calculating a heat dissipation feature parameter of natural heat dissipation of the machine by using at least one heat dissipation-related parameter of the machine and a measured temperature change of the machine in a cooling stage in which the machine stops operating and supply of lubricating oil stops;
calculating a heat influence parameter of an influence of the used lubricating oil volume on heat dissipation of the machine by using at least one heat dissipation-related parameter of the lubricating oil, a measured temperature value change of the machine, and the calculated heat dissipation feature parameter in a standby stage in which the machine stops operating and the lubricating oil is supplied; and
calculating a relationship function between the lubricating oil volume used by the machine during operation and a temperature change of the machine by using at least one operation parameter of operation of the machine, the calculated heat dissipation feature parameter, and the heat influence parameter in a heating stage in which the machine is operating and the lubricating oil is supplied, wherein the at least one operation parameter of the machine comprises one of a coefficient of friction, a stamping pressure, a diameter, a surface area of friction, and a number of stamping per minute or a combination thereof, wherein
the relationship function is configured to calculate the lubricating oil volume suitable to be used by the machine during operation under the predicted temperature value; and

controlling an oil supply system to supply the lubricating oil to the machine according to the calculated lubricating oil volume.
