Electric tool

A 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 a type of the accessory 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 distance traveled by the accessory during the action. And determine a state of the action based on a force applied to the workpiece and the distance. 一种电动工具，其包括电动工具壳体、附件、以及电子处理器。该壳体包括凹部和输入装置。该附件被配置为由该凹部接纳。该附件包括标识符。该电子处理器连接到该输入装置。该电子处理器被配置为：接收来自标识符的第一信号，基于第一信号确定附件类型，接收来自输入装置的第二信号，基于第二信号发起动作，确定工件的外径，计算由电动工具施加的力，确定附件在动
