Great Job! As usual, there are always many different methods and operations to complete the same machine job. Which CAM system did you use to program this part?
Thanks for your comment. This was a very simple part. I didn't use a CAM system, but wrote the G-code program directly onto the machine control (I've been doing that for 40 years). For more complex parts, I use MasterCam - usually version 9, but I'm learning version X4.
I only had two parts to make. If I had needed a larger batch of parts, there are several things I'd have done to make it run more efficiently.
I'm completely new to cnc machining. Is this a simple part to program? A complete novice could program this? How can you get your hands near the cutter to apply oil as you do for tapping, I thought these machines were safety interlock guarded. Thanks.
Thanks for watching and commenting. This was simple to program. I did use tool radius compensation, but that is easy too.
I was able to reach in and apply the tapping fluid because the table and tool feed were temporarily turned off. After lubricating the tap, I turned on the machine feed again.
@1471perry I was taught always to centerdrill regardless of the material if using basic HSS/HSS-CO drills. Most of the basic HSS drills don't have selfcentering geometry.
Thanks for your comment. Often, when a "stubby" drill is used (about 2 cm sticking out of the drill chuck), a centerdrill is not needed. Stubby drills don't flex enough to wander away from the target like longer drills can.
I agree, but didn't have a shorter drill that size. Needing only 2 parts, it didn't waste much time running the extra tool. Had it been a production run of many parts, then I would have made a more efficient program.

if u used a shorter drill i think u could have gotten away without centre drilling first, its only aluminum

nice tricky placement for the part-stop....it scarred me when I saw that endmill contouring the part! :)
