Rapid back up to Z0 and check. If machine is repeating fine then: Open g-code in an editor or open it in https://ncviewer.com. check for a flat area and see what depth the g-code is actually programmed for ( not what you . The best way I can come up with to compensate is (after cutting the top half) to move my machine back to it's zero (g0 x0 y0 z0) and then I perform: g0 z1 <- move up one . Flipping a part like that, if the machine is referenced .020" away from a reference, and the part is flipped it's now .040" off. The best way to do this is make a fixture with holes at .
Find your part zero quickly and accurately with CNCCookbook's 8 methods for locating it on your CNC machine. Increase your efficiency today. I have a CNC setup (as most of CNC are) with a Z axis that points towards the work piece/stock, meaning a Z increment is milling into the material. Whatever I do, the Fusion . Or you could just check the Flip X box in the CAM setup for any given part, but that just feels weird. Air cuts and simulation both in Mach3 and Fusion are your new friends. Using the free version of Fusion does have some limitations, one being is that you pretty much have to run each operation as a seperate G code file.
G51 is a G-code function that allows the CNC programmer to scale or mirror the coordinates of a part program. This can be useful for creating symmetrical or proportional shapes, or for adjusting the size of a part without changing the original program. G51 can also be used to flip the direction of a contour or a hole pattern. Usage format For two sided carvings, something like a guitar body, I like to zero to the left front corner of a fixed position on the machine with the part at a fixed point on the X and Y axis. You only need to insure that the alignment is . Even if the first op took stock off all surfaces of the part profile, once flipped tramming the original edges will find the same centroid, provided he trams at the part center lines. If the new centroid isn't at machine zero, he'll have .

likely using the same work offset for 1st and 2nd operation. stock is probably 1/16" oversized allowing for .030 off one side to clean, flip the part over and clean the last .030 down to Z0.0 so both sides have a nice surface First run was prototypes (50 pcs) and the fixture wasn't the greatest but it worked to get the job out the door. I milled the face, longer side and profile, inside pocket, and cutout in the side in one step. Then I flipped the part and inserted a plug to remove the remaining stock on the back and pocket out the underside of the flanges.

The above video shows the part where it’s FINALLY cutting the outer circle, the victory lap. But you can see the gashes in the plywood where I screwed up, forgetting to pause and raise the bit between cuts. In fact, since I didn’t understand how to adjust the bit depth, the program finished and the sled still wasn’t cut all the way through.
I have a CNC setup (as most of CNC are) with a Z axis that points towards the work piece/stock, meaning a Z increment is milling into the material. Whatever I do, the Fusion CAM produced a GCODE that has the direction wrong, It is milling against Z axis. So The retract/clearance is not running off the stock, but into it. I'm not able to find anything in the .
Thus, when you command G00 Z0, then T1 will move 5 inches towards the part. For the second end of the part, let us say it's chucked length causes it to stick 2" further out of the chuck. In the second half of the program, I must return the machine to home, then, redefine the coordinate system shift, by changing the Z value of the G50 in the . You could also make a fixture plate that precisely locates the flipped part by features and indicate the fixture. Or just buy a longer endmill.. 09-17-2013, 11:18 PM #5. zero_divide. View Profile .
