## Abstract

Systems and methods for determining a status of an action performed by a power tool. For example, the power tool includes a power tool housing, an accessory, and an electronic processor. The housing includes a recess and an input device. The accessory is configured to be received by the recess. The accessory includes an identifier. The electronic processor is connected to the input device. The electronic processor is configured to receive a first signal from the identifier, determine an accessory type based on the first signal, receive a second signal from the input device, initiate an action based on the second signal, determine an outer diameter of the workpiece, calculate a force applied by the power tool, determine a distance traveled by the accessory during the action, and determine a status of the action based on the force applied to the workpiece and the distance.

## Claims

### Claim 1

A method for determining a status of an action performed by a power tool on a workpiece, the method comprising:
identifying a type of accessory received by the power tool;
detecting an initiation signal from an input device associated with the power tool to perform the action on the workpiece;
initiating the action on the workpiece based on the initiation signal;
determining a pressure applied to the workpiece by the accessory during the action performed on the workpiece;
determining a distance traveled by the accessory during the action performed on the workpiece; and
determining, after performing the action on the workpiece, whether the action performed on the workpiece was successful based on the pressure and the distance.

### Claim 2 (depends on 1)

The method of claim 1, further comprising identifying a size and a material of the workpiece received by the power tool,
wherein the size and the material of the workpiece are received from an external device.

### Claim 3 (depends on 1)

The method of claim 1, further comprising:
determining the accessory received by the power tool is compatible with the power tool by comparing the type of accessory to a look-up table, and
stopping, in response to determining the type of accessory is not compatible with the power tool, operation of the power tool.

### Claim 4 (depends on 1)

The method of claim 1, wherein the accessory is a crimp die including an upper die and a lower die.

### Claim 5 (depends on 4)

The method of claim 4, further comprising:
determining, in response to identifying the type of accessory, that the upper die matches the lower die.

### Claim 6 (depends on 1)

The method of claim 1, determining, after performing the action on the workpiece, whether the action performed on the workpiece was successful based on the pressure and the distance includes:
calculating a force applied by the accessory based on the pressure applied to the workpiece by the accessory and the distance traveled by the accessory; and
determining whether the force applied by the accessory is within force bounds associated with the type of the accessory.
