CNC 6040 Router Accuracy vs Speed Testing

After making several workpieces with my CNC 6040 Router, I learned that the faster I let the machine move, the larger the inaccuracies in my workpieces get. So slowing the machine down is necessary if a workpiece requires a specific accuracy. For small programmes the difference between 3 or 4 minutes waiting isn’t that big of a deal. But for larger programmes the difference between 3 and 4 hours is quite substantial. ...

To test the relation between Accuracy and the Speed the Gantry of the CNC 6040 Router moves, I decided cut one design 7 different times. Every time with different Feed, Acceleration and Rapids. To compensate for the crooked bed, I fased some plywood to create a flat workspace. Because all the sevens wooden blocks had the same pre-cut holes setting up a new job was pretty easy. This was the first time that I did repetitive work on the CNC 6040 Router and I got a small collision with a screw head. So before I could proceed with the test I had to calibrate the axis. The calibration of the axis was done quick and dirty. My stepper driver is of such low quality that I have to be happy with a 0.2-0.3 mm accuracy. So I didn’t bother to warm up the motors, make sure my dial gauge was 100% level and I measured only 25 mm instead of the entire table length. I think that this video gives a much better in-depth explanation of the process. https://goo.gl/di8MRN When al the workpieces where finished I it was finally time to measure everything and see what the different CNC values had produced. The final conclusion is that I can save 27 % in cycle time by speeding up my CNC 6040 Router, without losing the 0.2-0.3 mm accuracy.
