Guilford Dairy galvanized smaller size milk boxmeasures 11" x 8" wide x 9" deep. Has metalhandle and metal interior. Name is embossed onfront. Lid has small dent on one edge and handledrags on one side slightly. Overall very good .
Almost certainly a machine problem. All of the normal mechanical things should be addressed. Make sure belts are tight. Make sure pinion gears are not loose. Check for binding or another problem that would cause you to lose steps. The first thing I would do is to run the calibration test pattern to establish a baseline for how well calibrated your machine is. The baseline test . I've been cutting 2 circle profiles about .100" apart. They come out not circles, but slight eclipses. The diameter is 8.00" and the ellipse minor diameter and major diameter will .

The diameter of the circle doesn't matter, both a 2" diameter circle and a 4" diameter circle are .020 undersized. This makes me think it is not calibration, it was checked . Did it fix the issue with the circle not being in the correct location? That could be from not setting the zero in the lower left corner before creating the G code. I’ve only used . Here, we will discuss 5 of the most important faults that will jeopardize your CNC machine accuracy. We will also disclose how to check and improve them to get better .

Almost certainly a machine problem. All of the normal mechanical things should be addressed. Make sure belts are tight. Make sure pinion gears are not loose. Check for binding or another problem that would cause you to lose steps. The first thing I would do is to run the calibration test pattern to establish a baseline for how well calibrated your machine is. The baseline test will test your machine in the far corners where it is likely to be the least accurate, and it will test across long distances where errors are most pronounced. If the machine has been working ok & has developed this problem then it is likely to be some form of binding, The most common culprit from what I have read is the aluminium type sprung couplings between the motor & ballscrew.

I've been cutting 2 circle profiles about .100" apart. They come out not circles, but slight eclipses. The diameter is 8.00" and the ellipse minor diameter and major diameter will end up about .020" different. On the Carve pro preview, they are perfect circles, but on the machine, they are eclipses. The problem is the circle has a small flat spot on one side. I have tried slightly different size circles 20mm & 30mm and it appears on all of them. I am using Mach 3 on a Proxxon MF70 CNC if that helps with just a profile cut tool path and a double fluted 1mm end mill. Has anyone seen this problem or know what could be causing it. Thanks Jason
Small circles are the most difficult thing to cut on a CNC. To get good results, you have to eliminate all sources of flex in the machine. What it looks like to me, is that you have flex or backlash in the up and down direction. If you cut a 1", or 2" pocket, is it . I interpolated a 2" inside diameter and the error would repeat with every cut; with or without cutter comp. I will find out if the y axis is locating correctly when I put up the next job which requires a bolt circle. When i cut a circle of any size the ends of the circle are truncated. (More noticeable in larger circles). I've included a picture of the problem. It looks small in the photo but for inlays etc it is causing me problems. The issue happens on the far ends of the X-Axis of the circle. Need help cutting better circles/arcs. I have a TREE VMC1060, it's 40x20 box way machine with yaskawa ac servos/drives, and dynapath delta 50 control. I've had it about a year, and have worked out a couple issues. I'm mostly happy with the machine, except I'm sort of disappointed with how bad it cuts circles and arcs.
The diameter of the circle doesn't matter, both a 2" diameter circle and a 4" diameter circle are .020 undersized. This makes me think it is not calibration, it was checked and found to be bang on. There is no play in the machine, and the circles are perfectly round and measure the same side to side as they do top to bottom. Almost certainly a machine problem.
