Abstract

Systems, devices, and methods including selecting one or more sequences of machining types for a feature of one or more features, where the selection of the one or more sequences of machining types is based on the feature and a database of prior selections of machining types; selecting one or more tools for the selected one or more sequences of machining types, where the selection of the one or more tools is based on the feature, the selected one or more sequences of machining types, and a database of prior selections of one or more tools; and selecting one or more machining parameters for the selected one or more tools, where the selected machining parameters are based on the feature, the selected one or more sequences of machining types, the selected one or more tools, and a database of prior selections of one or more machining parameters.

First claim

What is claimed is:

1. A method comprising:
selecting one or more sequences of machining types for a feature of one or more features, wherein the selection of the one or more sequences of machining types is based on the feature and user's machining selections from a database of prior selections of machining types;
selecting one or more tools associated with the selected one or more sequences of machining types;
determining one or more machining parameters for the selected one or more tools, wherein the determined one or more machining parameters are based on whether the selected one or more sequences of machining types is using inefficient or incorrect parameters by comparing the determined one or more machining parameters with at least one of: dataset of another user, historical data of a same user, and default parameters recommended by a manufacturer of the machining tool;
tagging the determined one or more machining parameters based on a threshold to not be used for training process and given less weight for purposes of determining future predictions;
determining a machining workflow prediction in a computer aided manufacturing (CAM) environment based on the selected one or more sequences of machining types, the selected one or more tools, and the determined and untagged one or more machining parameters, thereby determining the machining workflow prediction based on a user's skill set and experiential habits.

2. The method of claim 1 , wherein the determined one or more machining parameters comprise at least one of: speed, feed rate, and motion pattern.

3. The method of claim 1 , wherein determining more accurate machining workflow prediction in comparison to a set of previous predictions is based on the execution of more models.

4. The method of claim 3 , further comprising:
assigning a weight to a previous prediction of the set of previous predictions.

5. The method of claim 1 , further comprising:
determining a set of user preferences; and
associating the determined set of user preferences with machining tools.

6. The method of claim 1 , wherein determining a machining workflow prediction is based on determining energy-efficient toolpath having least number of movements, cutting operations, and cutting time, thereby reducing unneeded movements and cycle time combined with shortened tool lengths.

7. The method of claim 1 , wherein database comprises historical data collected over a period of time.

8. The method of claim 1 , wherein selecting one or more sequences of machining types is further based on a user's history of machining a pocket for the machine tool.

9. The method of claim 1 , wherein the determined machining workflow prediction comprises predicted parameters for a tool; wherein the predicted parameters for a tool include at least one of: a tool style, a tool diameter, a cutting length, a shank diameter, and a tool radius.

10. The method of claim 1 , wherein the determined machining workflow prediction is transmitted to a user interface at the Computer aided manufacturing (CAM) used to program computer numerical control (CNC) machine for implementation by a user.

11. A system comprising:
an Operation Sequence Classifier Component having a processor and addressable memory, wherein the Operation Sequence Classifier Component is configured to select one or more sequences of operations for each feature of one or more features;
a Tool Parameters Predictor Component having a processor and addressable memory, wherein the Tool Parameters Predictor Component is configured to:
receive the selected one or more sequences of operations, each feature of the one or more features, and one or more prior tool parameters; and
select one or more tool parameters based on the received selected one or more sequences of operations, each feature of the one or more features, and the one or more prior tool parameters;

an Operation Parameter Predictor Component having a processor and addressable memory, wherein the Operation Parameter Predictor Component is configured to:
receive the selected one or more sequences of operations, the one or more prior tool parameters, each feature of the one or more features, the one or more prior tool parameters, and the selected one or more tool parameters;
determine one or more operation parameters based on the received selected one or more sequences of operations, the one or more prior tool parameters, each feature of the one or more features, the one or more prior tool parameters, and the selected one or more tool parameters, wherein the determined one or more operation parameters are based on whether the selected one or more sequences of operations is using inefficient or incorrect parameters by comparing the determined one or more operation parameters with at least one of: dataset of another user, historical data of a same user, and default parameters recommended by a manufacturer;
tag the determined one or more operation parameters based on a threshold to not be used for training process and given less weight for purposes of determining future predictions; and
determine a machining workflow prediction in a computer aided manufacturing (CAM) environment based on the selected one or more sequences of operations, the selected one or more tools, and the determined and untagged one or more operation parameters, thereby determining the machining workflow prediction based on a user's skill set and experiential habits.
