A tool management system of machine tools, applied to at least one tool, and comprising:
- a reader configured for reading at least one category parameter of the tool according to a tool index code of the tool;
- a receiver configured for receiving real-time process information of the tool with a preset periodicity;
- a storage unit configured for storing the tool index code, the category parameter, and the real-time process information;
- a processor configured for processing a weighting algorithm to obtain a result according to the category parameter and the real-time process information;
- and
- a control unit configured for sending a control instruction according to the result,
- wherein the weighting algorithm is a total lifetime (T) of the tool minus an accumulated using time (Ta) and a real-time using time (Trt),
- wherein the real-time using time is defined as a summation of products, each of which is a product of the preset periodicity, a shaft current ratio and a vibration magnitude ratio, wherein the shaft current ratio is a ratio of a shaft current value to a shaft current base value, and the vibration magnitude ratio is a ratio of a vibration magnitude to a vibration base magnitude.

- a processor configured for executing a weighting algorithm to obtain a result according to the category parameter and the real-time process information;
- and
- a control unit configured for sending a control instruction, according to the result, via the network interface,
- wherein the weighting algorithm is a total lifetime (T) of the tool minus an accumulated using time (Ta) and a real-time using time (Trt),
- wherein the real-time using time is defined as a summation of products, each of which is a product of the preset periodicity, a shaft current ratio and a vibration magnitude ratio, wherein the shaft current ratio is a ratio of a shaft current value to a shaft current base value, and the vibration magnitude ratio is a ratio of a vibration magnitude to a vibration base magnitude.
A method for tool management of machine tools, applied to at least one tool, and the method comprising steps of:

- determining whether the result is matched to a condition;
- if the result is matched to the condition, sending a control instruction;
- and
- if the result is not matched to the condition, redoing the steps from the step of receiving the real-time process information,
- wherein the weighting algorithm is a total lifetime (T) of the tool minus an accumulated using time (Ta) and a real-time using time (Trt),
- wherein the real-time using time is defined as a summation of products, each of which is a product of the preset periodicity, a shaft current ratio and a vibration magnitude ratio, wherein the shaft current ratio is a ratio of a shaft current value to a shaft current base value, and the vibration magnitude ratio is a ratio of a vibration magnitude to a vibration base magnitude.
