Power tool angle assist
Power tool methods and systems are provided for aligning a power tool to implement an angled cut in a workpiece. The power tool includes a first distance sensor and a second distance sensor. The power tool measures a first distance to the workpiece with the first distance sensor and a second distance to the workpiece with the second distance sensor. The power tool calculates an angle between the power tool and the workpiece based on the first and second distances, and indicates the angle via an angle output indicator of the power tool. The power tool may measure an angle between the power tool and the workpiece using a proximate edge and a distal edge of the workpiece, and indicate whether the power tool maintains a correct angle as it traverses a cut through the workpiece from the proximate edge to the distal edge.
1. A power tool for implementing an angled cut, the power tool comprising:
a housing;
a guard profile,
a direction detector disposed on the guard profile, the direction detector including a ball bearing that rotates in a direction according to movement of a workpiece relative to the power tool when the workpiece is in contact with the ball bearing;
an operation trigger;
a motor;
a controller supported by the housing, the controller including an electronic processor and a memory storing instructions that when executed by the electronic processor configure the controller to:
activate the motor according to actuation of the operation trigger;
receive a first signal from the direction detector, the first signal indicating a first direction of the power tool relative to the workpiece as the power tool traverses the workpiece;
receive a second signal from the direction detector, the second signal indicating a second direction of the power tool relative to the workpiece as the power tool traverses the workpiece;
compare the first direction of the power tool relative to the workpiece to the second direction of the power tool relative to the workpiece; and
take a responsive action when the first direction of the power tool relative to the workpiece is different from the second direction of the power tool relative to the workpiece.
2. The power tool of claim 1 , wherein the responsive action includes shutting-off the motor.
3. The power tool of claim 1 , further comprising a user interface; wherein the responsive action includes indicating, via the user interface, that a direction of the power tool relative to the first direction of the power tool has changed.
