Although we have not cut anywhere near that number of parts on a chop saw, we do use them. We also have a LARGE horizontal band saw.
Both will do the job well IF they are used and set up properly.

Below is my ASSUMPTION based on the picture alone. I do not have enough factual information to give anything more than an assumption here.

My guess from looking at the picture is that the cut was from the top with a 45 degree vertical rotation to the blade. The part being cut was standing on it's narrow edge and not clamped securely. This set up is NOT ideal for a chop saw.

Lay the part with the larger side down. Use the horizontal rotation of the saw to set the angle. CLAMP THE PART SECURELY. Sorry for the all caps, but the importance of securing the part can not be understated.

It just struck me, the saw may not have been a Miter Saw! If not, it was the wrong tool for the job.
