Abstract
A method and apparatus for fabricating roofing crickets includes the steps of generating the dimensions of roofing cricket components, which when assembled, form the roofing cricket. Knowing the dimensions of each cricket component, a cutting assembly which utilizes a rotatable cutting saw and is controllable in an X-Y plane is controlled to cut each cricket component from a tapered insulation board. The cricket components can then be assembled into the roofing cricket.
Claims14
A method of making a cricket, comprising the steps of:
- a) generating respective data on a plurality of cricket component shapes, each cricket component shape having specified dimensions and corresponding to a respective cricket component, said plurality of cricket component shapes forming a shape corresponding to said cricket;
- b) providing a cricket sheet material having a tapered form of predetermined slope;
- c) providing a cutting machine comprising a saw blade, said cutting machine being controllable to cut along a selected path in an X-Y cutting plane of one side of said cricket sheet material;
- d) controlling an angular position of said saw blade about a Z axis perpendicular to the X-Y plane to cut said cricket sheet material along the selected path to produce a first cricket component based on a generated cricket component shape;
- and
- e) continuing said controlled cutting of one of said cricket sheet material or another cricket sheet material according to step d) to produce said plurality of cricket components.
3 more elements
An apparatus for making a cricket, comprising:
- a) means for generating and storing respective data on a plurality of cricket component shapes, each cricket component shape having specified dimensions and corresponding to a respective cricket component, said plurality of cricket component shapes forming a shape corresponding to said cricket;
- b) a cutting machine comprising a saw blade, controllable to cut a piece of cricket sheet material having a tapered form of predetermined slope, along a selected path in an X-Y cutting plane corresponding to one side of said cricket sheet material;
- c) a controller for receiving the generated data and for controlling movement of said saw cutting machine, including an angular position of said saw blade about a Z axis perpendicular to the X-Y plane, to form said plurality of cricket components by sequentially cutting the cricket sheet material into said plurality of cricket components.
