Abstract
A method and apparatus for cutting a workpiece, such as a panel, in particular a sandwich panel, in which an elongate milling cutter 21 is mounted in axially spaced bearings 18, 19. A workpiece is supported on a support 11 and a relative cutting sweep movement between the supported workpiece and the elongate cutter is caused to take place in at least one direction transverse to the axis of the cutter, whereby the cut is made in that transverse direction.
Claims16
A method of cutting a workpiece, to sever a part of the workpiece, said method comprising the steps of rotatably supporting an elongate milling cutter in bearings which are spaced apart in an axial direction of the cutter, said cutter having a longitudinal axis and an effective cutting length related to a thickness dimension of the workpiece to be cut, supporting the workpiece in cutting position relative to the cutter and effecting relative cutting sweep movement between the workpiece and the cutter, said relative movement taking place in at least one cutting direction transverse to the axis of the cutter, whereby a cut is made in the workpiece in the cutting direction wherein said cutter has a sharpened end and prior to making said cut, said sharpened end and a relevant one of said bearings are temporarily disengaged from one another, relative movement is effected between said workpiece and said cutter in the axial direction of said cutter to pierce through said workpiece, and said cutter and said relevant bearing are then re-engaged for carrying out said cutting sweep movement.
A method of cutting a workpiece, to sever a part of the workpiece, said method comprising the steps of rotatably supporting an elongate milling cutter in bearings which are spaced apart in an axial direction of the cutter, said cutter having a longitudinal axis and an effective cutting length related to a thickness dimension of the workpiece to be cut, supporting the workpiece in cutting position relative to the cutter and effecting relative cutting sweep movement between the workpiece and the cutter, said relative movement taking place in at least one cutting direction transverse to the axis of the cutter, whereby a cut is made in the workpiece in the cutting direction wherein said workpiece is a planar panel and wherein said at least one cutting direction in which said relative movement takes place is angled with respect to the plane of the panel.
A workpiece cutting apparatus comprising supporting means to support a workpiece, a pair of axially spaced apart bearings, an elongate milling cutter mounted for rotation in said bearings about a longitudinal cutter axis, a frame member connecting the bearings, said cutter having an effective cutting length related to a thickness dimension of the workpiece to be cut, means to rotate said cutter about said axis and means to effect a cutting sweep of said cutter relative to said supporting means in at least one cutting direction transverse to the axis of the cutter to make a cut in the workpiece in the cutting direction wherein said frame is formed of sheet material having a thickness less than the diameter of said cutter, whereby the frame may pass through the cut formed by the cutter.
A panel cutting apparatus comprising supporting means to support a panel, a pair of axially spaced apart bearings, an elongate milling cutter mounted for rotation in said bearings about a longitudinal cutter axis, a frame member connecting the bearings, said cutter having an effective cutting length related to a thickness dimension of the panel to be cut, means to rotate said cutter about said axis and means to effect a cutting sweep of said cutter relative to said supporting means in at least one cutting direction transverse to the axis of the cutter to make a cut in the panel in the cutting direction wherein said supporting means is adapted to mount a panel in an angularly adjustable plane substantially perpendicular to the axis of said milling cutter, and said at least one cutting direction in which said relative movement takes place is angled with respect to the plane of the panel.
A workpiece cutting apparatus comprising support means for supporting a planar workpiece in a specified plane, a pair of axially spaced apart bearings, an elongate milling cutter mounted for rotation in said bearings about a longitudinal cutter axis, a frame member connecting the bearings, said cutter having an effective cutting length related to a thickness dimension of the workpiece to be cut, means to rotate said cutter about said axis, and means to effect a cutting sweep of said cutter relative to said supporting means in at least one cutting direction which is angled with respect to the plane of the workpiece thereby providing relative axial movement between the cutter and the workpiece during said cutting sweep movement.
A workpiece cutting apparatus comprising support means for supporting a planar workpiece in a specified plane, a pair of axially spaced apart bearings, an elongate milling cutter mounted for rotation in said bearings about a longitudinal cutter axis, a frame member connecting the bearings, said cutter having an effective cutting length related to a thickness dimension of the workpiece to be cut, means to rotate said cutter about said axis and means to effect a cutting sweep of said cutter relative to said supporting means in at least one cutting direction substantially parallel to said plane wherein the cutter axis is disposed at a non-perpendicular angle to said cutting direction.
