Abstract

A system, method, and computer-readable medium for providing a user interface. The system includes circuitry configured to generate chatter information based on sensor data collected from a machining operation of a machine performed at a previously selected tool speed setting. The chatter information includes a chatter level value and a chatter frequency value. A plurality of different candidate tool speed settings is determined based on the generated chatter frequency value from the machining operation. The circuitry generates the user interface that includes a plurality of different tool speed settings, including the previously selected tool speed setting and the plurality of different candidate tool speed settings for selection by a user. The user interface is configured to indicate the chatter level value for the previously selected.

First claim

What is claimed is:

1. A system, comprising:
circuitry configured to
generate chatter information based on sensor data collected from a machining operation performed at a previously selected tool speed setting, the chatter information including a chatter level value and a chatter frequency value,
determine a plurality of different candidate tool speed settings, which are predicted to reduce or eliminate chatter, based on the generated chatter frequency value from the machining operation, and
generate a user interface that includes a plurality of different tool speed settings, including the previously selected tool speed setting and the plurality of different candidate tool speed settings for selection by a user, wherein
the user interface is configured to indicate the chatter level value for the previously selected tool speed setting, wherein

the user interface is configured to display a subset of the plurality of different tool speed settings, each of the subset of the plurality of different tool speed settings being represented by a different element, and
the subset of the plurality of different tool speed settings is determined based on a user input.

2. The system according to claim 1 , wherein
the circuitry is further configured to, when one of the different candidate tool speed settings is selected by the user,
generate second chatter information based on sensor data collected from a machining operation performed at the selected one of the different candidate tool speed settings, and
determine a second plurality of different candidate tool speed settings, which are predicted to reduce or eliminate chatter, based on a chatter frequency value included in the second chatter information, wherein

the plurality of different tool speed settings, included in the user interface, is updated to include the second plurality of different candidate tool speed settings.

3. The system according to claim 1 , wherein
the plurality of different tool speed settings includes a plurality of previously selected tool speed settings,
the circuitry is further configured to determine, for each of the previously selected tool speed setting, a color that represents a measured chatter level value of the respective previously selected tool speed setting, and
the user interface is configured to indicate, for each of the previously selected tool speed settings, the measured chatter level value of the respective previously selected tool speed setting using the determined color for the respective previously selected tool speed setting.

4. The system according to 3 , wherein the circuitry is further configured to:
determine the color that represents the chatter level value of the respective previously selected tool speed setting based on a color scale in which green represent a predetermined minimum chatter level and red represents a predetermined maximum chatter level.

5. The system according to claim 1 , wherein the circuitry is further configured to:
determine when one of the elements is selected, and
activate a tool speed corresponding to the selected one of the elements.

6. The system according to claim 1 , wherein each of the elements includes corresponding lobe information that identifies a stability lobe number corresponding to the tool speed setting associated with the respective element.

7. The system according to claim 1 , wherein the user interface includes a history bar that indicates a predetermined permissible range of tool speed settings and an indication of which portion of the predetermined permissible range corresponds to the subset of the plurality of different tool speed settings.

8. The system according to claim 7 , wherein the history bar is configured to display a measured chatter level for each previously selected tool speed setting included in the user interface.

9. A method for controlling chatter, the method comprising:
generating, by circuitry, chatter information based on sensor data collected from a machining operation performed at a previously selected, tool speed setting, the chatter information including a chatter level value and a chatter frequency value;
determining, by the circuitry, a plurality of different candidate tool speed settings, which are predicted to reduce or eliminate chatter, based on the generated chatter frequency value from the machining operation;
generating, by the circuitry, a user interface that includes a plurality of different tool speed settings, including the previously selected tool speed setting and the plurality of different candidate tool speed settings for selection by a user; and
indicating, in the user interface by the circuitry, the chatter level value for the previously selected tool speed setting, wherein
the user interface is configured to display a subset of the plurality of different tool speed settings, each of the subset of the plurality of different tool speed settings being represented by a different element, and
the subset of the plurality of different tool speed settings is determined based on a user input.

10. A non-transitory computer-readable medium storing a program which when executed by a computer, causes the computer to perform a method for controlling chatter, the method comprising:
generating chatter information based on sensor data collected from a machining operation performed at a previously selected tool speed setting, the chatter information including a chatter level value and a chatter frequency value;
determining a plurality of different candidate tool speed settings, which are predicted to reduce or eliminate chatter based on the generated chatter frequency value from the machining operation;
generating a user interface that includes a plurality of different tool speed settings, including the previously selected tool speed setting and the plurality of different candidate tool speed settings for selection by a user; and
indicating, in the user interface, the chatter level value for the previously selected tool speed setting, wherein
the user interface is configured to display a subset of the plurality of different tool speed settings, each of the subset of the plurality of different tool speed settings being represented by a different element, and
the subset of the plurality of different tool speed settings is determined based on a user input.

11. The non-transitory computer-readable medium according to claim 10 , wherein
the plurality of different tool speed settings includes a plurality of previously selected tool speed settings,
the method further includes determining, for each of the previously selected tool speed setting, a color that represents a measured chatter level value of the respective previously selected tool speed setting, and
the user interface is configured to indicate, for each of the previously selected tool speed settings, the measured chatter level value of the respective previously selected tool speed setting using the determined color for the respective previously selected tool speed setting.
