Abstract

A method is provided for controlling operation of a power tool, such as a drill driver. The method begins with one or more descriptors for a fastening application being received by a controller residing in the power tool, where the descriptors are indicative of a fastening application to be performed by the power tool and are received via a wireless data link from a computing device located remotely from the power tool. The descriptors are translated into a threshold value used by a fastener setting algorithm and the threshold value is stored in a data store of the power tool. During a subsequent fastening operation performed using the tool, an operating parameter of the power tool is monitored and evaluated in accordance with the fastener setting algorithm, including the updated threshold value. Example operating parameters include current delivered to the motor and speed of the motor.

Claims

1. A method for controlling operation of a power tool having an electric motor drivably connected to an output spindle to impart rotary motion thereto, comprising:

entering, in a computer device remote from the power tool, one or more descriptors for a fastening application, where the descriptors are indicative of a fastening application to be performed by the power tool and the descriptors include a fastener diameter;

receiving, by a controller residing in the power tool, the descriptors for a fastening application, I and where the descriptors are received via a wireless data link from the computing device;

translating, by the controller, the descriptors into a threshold value used by a fastener setting algorithm, where the translating occurs in response to receiving the one or more descriptors by the controller;

updating, by the controller, a data store with the threshold value, where the data store resides on the power tool;

sampling periodically, by the controller, current delivered to the electric motor;

evaluating, by the controller, the current delivered to the electric motor in accordance with the fastener setting algorithm, including the threshold value;

further comprising, evaluating, by the controller, the current delivered to the electric motor in accordance with the fastener setting algorithm when a clutch setting of an electronic clutch is in a drive mode;

disregarding, by the controller, torque applied to the output spindle when the clutch setting of the electronic clutch is a drill mode, the clutch setting being selectable from a drill mode and a drive mode; and

setting, by the controller, the clutch setting to a drill mode, where the setting occurs in response to receiving the one or more descriptors by the controller.

2. The method of claim 1 wherein the descriptors further includes a fastener length.

3. The method of claim 1 further comprises displaying an indicia of the descriptors on a display of the power tool, where the displaying occurs in response to receiving the one or more descriptors by the controller.

4. The method of claim 1, further comprises prompting the tool operator to confirm setting of the clutch setting to drill mode prior to the step of setting the clutch setting to drill mode.

5. The method of claim 1, wherein the parameter value further includes a material of the workpiece.

6. A method for controlling operation of a power tool having an electric motor drivably connected to an output spindle to impart rotary motion thereto, comprising:

receiving, by a controller residing in the power tool, a parameter value for a fastening application, where the parameter value is received via a wireless data link from a computing device located remotely from the power tool;

translating, by the controller, the parameter value into a threshold value used by a power tool operating algorithm;

updating, by the controller, a data store with the threshold value, where the translating and updating occurs in response to receiving the parameter value by the controller and the data store resides on the power tool;

monitoring, by the controller, an operating parameter of the power tool during a fastening operation by the power tool; and

evaluating, by the controller, the operating parameter in relation to the threshold value of the power tool operating algorithm;

wherein the parameter value includes a diameter of the fastener; and

wherein the method further comprises evaluating, by the controller, the current delivered to the electric motor in accordance with the fastener setting algorithm when a clutch setting of an electronic clutch is in a drive mode;

disregarding, by the controller, torque applied to the output spindle when the clutch setting of the electronic clutch is a drill mode, the clutch setting being selectable from a drill mode and a drive mode; and

setting, by the controller, the clutch setting to a drill mode, where the setting occurs in response to receiving the parameter value by the controller.

7. The method of claim 6 wherein the operating parameter is one of current delivered to the electric motor or speed of the electric motor.

9. The method of claim 6, further comprises prompting the tool operator to confirm setting of the clutch setting to drill mode prior to the step of setting the clutch setting to drill mode.

10. The method of claim 6, further comprising displaying, on the power tool, that the power tool is in a custom mode in which a user may perform the manually setting the at least one parameter value.

11. The method of claim 6, wherein the parameter value further includes a material of the workpiece.

8. The method of 6 wherein the parameter value further includes a length of the fastener, a material of a workpiece, a maximum speed of the electric motor or a size of the workpiece.
