摘要： An improvement for a power tool having a motor-driven working tool for performing an operation on a workpiece includes a material sensor positioned to sense the workpiece prior to operation by the working tool. The material sensor is configured to determine a material property of the workpiece and to generate a signal in response thereto. A processor coupled between the material sensor and the motor is configured to control the motor in response to the signal generated by the material sensor.

摘要： A power tool support system includes a base, a table top supported on the base and having a generally planar support surface, and a tool support assembly. The tool support assembly includes an arch-shaped support member attached to a first side portion of the base and which extends arcuately from the first side portion toward a second side portion of the base. An arch slide mount is slidably supported on the arch-shaped support member and positionable at a plurality of different angular positions along the arch-shaped support member. The tool support assembly includes a tool mount coupled to the arch slide mount and configured to releasably retain a cutting tool at a predetermined orientation with respect to the table top. The power tool support system may include a height adjustment assembly and a horizontal guide assembly and be configured to support one or more types of cutting tools.

摘要： A blade guard assembly for a power saw includes a bolt member, a blade guard housing, a mounting plate, an engagement nut, and a biasing member. The bolt member includes a head defining a first shoulder, a pivot shank extending from the head and defining a second shoulder, a support shank extending from the pivot shank, and a threaded shank extending from the support shank and located opposite from the head. The blade guard housing defines a blade space for at least partially covering a saw blade of a power saw and includes a hub defining a hub opening configured to pivotably receive the pivot shank therethrough and to seat on the first shoulder. The mounting plate is supported by a cutting arm of the power saw and defines a mounting opening. The biasing member remains uncompressed between the blade guard housing and the mounting plate.

摘要： A power table saw has a saw blade driven by a drive motor with power selectively supplied to the drive motor by actuation of a mains switch. A riving knife is provided that can be selectively positioned in an extended position and a retracted position relative to the blade. A blade guard is removably mounted to the riving knife in a position above the blade. A sensible element on the riving knife can be detected by a first sensor when the riving knife is retracted, the first sensor having a non-null state when the sensible element is adjacent the first sensor and a null state otherwise. A second sensor is configured to detect the presence of the blade guard and has a null state when the blade guard is detected and a non-null state otherwise. A controller is operable to determine the states of the first and second sensors and to disengage power to the drive motor when the mains switch is actuated when the states of the first and second sensors are different.
摘要翻译：功率台锯具有由驱动电机驱动的锯片，其中电力通过电源开关的启动选择性地供应给驱动电机。提供的劈刀可以选择性地定位在相对于刀片的延伸位置和缩回位置。刀片防护装置可拆卸地安装在刀片上方位置的劈刀上。当劈刀缩回时，劈刀上的显着元件可以由第一传感器检测到，当显示元件与第一传感器相邻时，第一传感器具有非零状态，否则为零状态。第二传感器被配置为检测刀片防护装置的存在，并且在检测到刀片防护装置时具有空状态，否则具有非空状态。控制器可操作以确定第一传感器和第二传感器的状态，并且当第一传感器和第二传感器的状态不同时，当市电开关被致动时，断开到驱动马达的电力。

摘要： A power tools incorporates a brushless or electronically commutated drive motor (BLDC). A number of drive trains are provided for connecting the BLDC to the drive shaft of a working tool, such as a rotary saw blade. In one aspect, the BLDC motor is disposed within an arm assembly of a power tool and provides power to the drive shaft of the tool through a gear train that minimizes the size and profile of the power tool.
