Abstract
Systems, computer-implemented methods and/or computer program products that facilitate generating operating parameters are provided. In one embodiment, a computer-implemented method comprises: generating, by a system operatively coupled to a processor, tool life models using a tool wear data set, wherein the tool wear data set is based on production data or predetermined data; and generating, by the system, operating parameters for machining operations based on the tool life models and baseline operational parameters.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A system, comprising:
a processor, operably coupled to a memory, and that executes computer executable components, wherein the computer executable components comprise:
a modeling component that generates a tool life model using a tool wear data set; and
a recommendation component that generates operating parameters for machining based on the tool life model and baseline operational parameters to minimize a total operating cost, wherein the total operating cost is represented by
C=C T +C F
where
C F =tool/insert usage costs per feature/part,
C T =cost of time per feature/part; and
a component that uses the generated operating parameters to control cutting speed and feed rate.
2 . The system of claim 1 , further comprising a data collection component that builds the tool wear data set through real-time collection of production data or predetermined data.
3 . The system of claim 2 , wherein the data collection component employs artificial intelligence to infer tool wear from the production data.
4 . The system of claim 1 , wherein the generated operating parameters include cutting speed and feed rate, and the baseline operational parameters include machine details, and machining parameters.
5 . The system of claim 1 , wherein the generated operating parameters reduces an initial cost to an updated cost, wherein the updated cost is lower than the initial cost, wherein the initial cost is cost of using the baseline operational parameters and the updated cost is cost of using the generated operating parameters.
6 . The system of claim 1 , wherein the production data includes measured tool wear value and operating data, wherein the operating data includes at least one of cutting time or temperature.
7 . The system of claim 1 , wherein the modeling component updates the tool life model based on a measured tool wear value.
