DEEP CAVITY PART WITH ISLAND USING INTEGRATED ROTARY TABLE
This part has a deep cavity and an island or protruding boss. One of the walls of the perimeter is at an angle and the island is at a different angle.
The raw material setup in a vise, here the origin of the part geometry is set with an edge-finder. The position of the vice is completely arbitrary. The Cartesian Display will allow the machinist to automatically align the vice jaw with X, then all that's left to do is indicate the corner representing the geometric origin.
The machinist may rotate the part at will to obtain the best machining strategy and to align the angled surfaces with X or Y in order to machine the angled surfaces. All the geometry is mathematically rotated so everything is where it should be no matter the orientation.
Look at all those chips !
That is MONEY !
This part took about 30 minutes to machine.
The finished part. All dimensions are within tolerance, and those tolerances were obtained with no in-process measurements or adjustments. Also no knowledge of the dimensions is required.
The only "adjustment" made in the machining process was to specify the actual size of the finishing endmill used. It was a 3/8" endmill but measures 0.372". The Cartesian Display uses the actual cutter diameter to make all calculations.
It is impossible* to imagine a part like this being machined on anything other than a CNC machine; but the milling was done in 30 minutes.
*impossible, no. But it could not be done in any practical amount of time, it would require a machinist with considerable experience and even then, you could not expect to make more than one part that way.
The green color is the cutter path that is displayed as the machinist moves the cutter. Everywhere the cutter goes it leaves behind the image of where it has been. This is the rough machining operation. The finish machining of the dimensions cannot be shown with photos alone. Please see YouTube videos of the system in action.
With the integrated rotary table, machining the angled features is easy. You simply identify the angled line you want to cut and the table is rotated to the correct angle to make that surface parallel to the X or Y axis -however you want to machine it. All the math to rotate the geometry is computed automatically.
