A part with MANUAL rotary table
Start by installing a precision rotary table. This example is using a manual rotary table, but the full power of the Tactical Cartesian Display is realized when the same rotary table is put under computer control and integrated with the Cartesian Display.
Install the splash guard made from a pizza pan and a cake container.
Install a generic steel fixture plate, this will hold the part fixture.
Install the actual part fixture. This custom made plate accepts the part blank and holds it exactly where I want it and uses no clamps.
Indicate a qualified edge on the fixture to be parallel to the X-axis. The part blank is installed also.
Indicate the previously machined hole in the part to set the DX,DY distance to the origin of rotation of the rotary table.
a Part with manual rotary table
Machining can begin, roughing with a 3/8" 2-flute endmill and finishing with a 1/4" 2-flute endmill.
In only a few seconds, the part is submerged under the flood coolant. This is not a problem with the Cartesian Display.
The splash guard contains all the coolant and chips. Imagine the mess this operation would make without it.
Machining complete. Using only the Cartesian
Display because you cannot see the machining action with all the coolant and chips.
The finished part. Tolerances of all dimensions easily held to +- 0.002" with no in-process measurements or adjustments.
Here the part is shown in the display. This part is actually part of a motor-mount for a computer-controlled motor drive project fore this same rotary table.
a Part with MANUAL rotary table
Shown here is a close-up of the roughing with the 3/8" endmill. Just staying away from the lines is enough to make sure stock is left for finishing.
Here the part is shown rotated, making the angled walls of the part parallel to the X-axis so perfectly straight cuts can be made on angular features. The rotary table is then rotated to the angle that the display tells you to rotate to. After all the other features are machined, the part is rotated to make the final cuts on the angled features.
