A notch cutting system includes a cutter guide that connects to a workpiece and establishes a cutting path for notching the workpiece. A notch cutter with a cylindrical cutting element engages the cutter guide. A rotary driver rotates the cutting element to remove workpiece material as the notch cutter traverses the aperture and the notch cutting system cuts a full-radius notch in the workpiece along the cutting path.

The present application relates to woodworking tools in general and in particular to a woodworking grooving planer. A woodworking grooving planer comprises a planer body, a planer cutter assembly, a planer cutter lifter, an axial locking mechanism and a radial locking mechanism; the grooving planer lift comprises a rotary leadscrew, a lifting slider, a lifting base, a guide rod and a stopper; rotating the rotatory handle can make the lifting slider drive the cutter assembly to move up or down; the axial locking mechanism and the radial locking mechanism can make the rotary screw thread press the lifting slider axially and radially, so that a close thread fit is established between the rotary screw and the lifting slider, thus effectively avoiding the problem of instability and imprecision caused by pitch clearance.

According to the method, a floor panel (2) is inserted between a lamellar retaining transport assembly (7) and a lamellar pressing transport assembly (8, 9); the floor panel (2) clamped between the moved lamellar retaining transport assembly (7) and the lamellar pressing transport assembly (8, 9) is subjected to a feed motion through linear movement; a cutting head (10, 11) is put into a rotary motion around axes of rotation (X1, X2) and parallel grooves (17, 21, 22) are machined in the underside (12) of the floor panel (2), using the feed motion imparted to it by the lamellar retaining transport assembly (7) and the lamellar pressing transport assembly (8, 9). The machining of the parallel grooves (17, 21, 22) in the underside (12) of the floor panel (2) is performed with the cutting head (10, 11) comprising a set of axially separated profile disc cutters having stepwise-changing diameters, the machining of the parallel grooves (17, 21, 22) being performed when the axis of rotation (X1, X2) of the spindle (23, 24) of the cutting head (10, 11) is inclined at an angle (+, ) relative to the plane of the underside (12) of the machined floor panel (2).
