A dust coupler adapted to different dust outlet tubes has a collecting pipe connector and an elastic sheathing element. The collecting pipe connector has a first end and a second end being opposite to each other. The first end is configured to be inserted into a collecting pipe of a dust collection system for woodworking. The elastic sheathing element is connected to the second end of the collecting pipe connector, has a mouth, and is configured to be elastically sheathed onto a dust outlet tube of a woodworking machine. A woodworker first mounts the dust coupler on the collecting pipe, and the collecting pipe can be combined with any one of different dust outlet tubes of different woodworking machines having different sizes via the dust coupler. The dust coupler allows the collecting pipe to be quickly combined with or detached from the dust outlet tube.

A method includes: receiving a recycled wood workpiece populated with a set of metal fasteners; accessing an internal imaging scan; detecting the set of metal fasteners embedded in the recycled wood workpiece based on internal features detected in the internal imaging scan; for each metal fastener in the set of metal fasteners, extracting an initial position and an initial orientation of the metal fastener from the internal imaging scan; generating a virtual model of the recycled wood workpiece based on the internal imaging scan; accessing an image captured by an optical sensor; detecting a first metal fastener in the recycled wood workpiece; deriving a first position and a first orientation of the first metal fastener; and, in response to identifying the first metal fastener analogous to an initial metal fastener in the virtual model, isolating the first metal fastener in the virtual model and generating a fastener removal schedule.

The present invention improves workability. A cutting work machine has a discharge channel, concave with a discharge opening open to the left, disposed at an outer peripheral portion of a saw cover. A discharge inlet portion that connects the saw cover and the discharge channel are formed at a front end of the discharge channel. Viewed from above, a side guide surface constituting the right-side surface of the discharge channel inclines to the left toward the rear. The rear surface of the discharge channel consists of a rear guide surface inclined to the rear toward the left side. Thus, cutting chips flowing towards the rear-end side of the discharge channel along the side guide surface hit the rear guide surface and changes the chip outflow direction to the left side (discharge opening side). With cutting chips being discharged substantially leftward from the discharge opening, the workability of the cutting work machine improves.
