These three dimensional snow flake ornaments are machined from both sides using an alignment pin method to ensure that both sides line up correctly. The Z Zero plane is set to the surface of the part while machining the first side and then set to the surface of the table while machining the second side. This technique insures that the thickness of the part is perfect regardless of whether the stock is the proper thickeness or not. Legacy customers can download the drawings, CAD/CAM files and G Code files from the Legacy Project Files page.
]]>In part 1 of this video series we show the basic plans for the oriental style pergola and how to joint and cutout the curved rafters. In the Live Webinars we show how to draw and design the pergola and two methods for creating the program for jointing the parts and how to design and draw. In the next video we will build the square tapered columns that feature a curved face and show how to wrap the parts around a 3" square steel tube.
]]>In this video we machine the table top and add the inlay to complete the three legged pedestal project.
]]>In this first video we show turning the spindle, carving the details and adding the indexed sliding dovetail slots. Then we show how to cut out the legs and mount them vertically in a fixture to mill the dovetail pins. In the next video we will mill the table top that features inlay.
]]>John Hennen of Legacy Woodworking Machinery used VCarve Pro and Conversational CAM to create the code to machine all of the parts for this wooden vise except the threads that are machined in the back plate. The program for tapping the threads was written in G Code. Legacy CNC customers can login and follow this link to download the files and codes to build the wooden vise project.
]]>In this final video you will see how we use one of Legacy's 5-axis turning / milling CNCs as a copy lathe to turn the cannon ball finial. You'll also see how we use a two flute straight cutter to mill the shoulder and then blend the profile into the bottom of the ball and mill the round tenon. Again you see the versatility of Legacy's CNC, on this one project we perform basic turning and ornamental turning as well as milling the square components, joinery and carving all on the same part.
]]>After milling the square base and top for the newel post we decided to carve a fleur de lys on three of the sides of the top section. The back side was left flat to receive the hand rail. Once the carving was complete we dry fit the assembly to make sure everything fit together the way it was designed.
]]>Machining the Round Mortise
Now you've seen how to draw a round mortise using a CAD program and then create the pocket milling routine using a CAM program, we'll show you how to clamp the part vertically in the machine, setup the work offset, setup the Z-axis using the mobile Smart Tool and machine the round mortise in the end of the base. Then we add the turning details.
]]>Using CAD & CAM Software
How many ways are there to mill a round hole? In this video we will show you one technique using TurboCAD to draw the size of the hole and then import the DXF file into SheetCAM to create the pocket milling program. The CAM software is where you define the depth of the hole, the depth per pass, the type of cut etc. These are not the only programs that can be used for this type of work. You could also use ArtCAM, Aspire, VCarvePro or any number of other CAD/CAM software packages to accomplish the same job. You could even write a simple code using GCode.
]]>Machining the Rope Twist Insert
Using Conversational CAM V3.1 we created the code for milling the rope twist on the insert piece and then milling the round tenons on each end of the piece. This insert piece could feature any design you wish. We chose to use a rope twist that turns in the opposite direction of the hollow spiral. This insert piece will bear the weight connect the parts together.
