I'm Stuggling With Chamfer Tools [SOLVED]
I'm trying to set up a 3/8" 90 degree 4 flute coated carbide Chamfer tool and figure out what feeds and speeds I'll be needing for my particular application.
I seem to be able to enter the correct information and get what looks like the correct angle and length on the tip of my tool in the display window but, the feeds and speeds seem very odd.
I've been told that although 90 degree Chamfer tools are listed at 90 degree, the angle of the flutes are actually 45 degrees on either side which adds up 90 degree. If this is the case, what is the correct angle to enter in the corresponding text field?
In the tool data base I found 90 degree 1/4" and 1/2" Chamfer tools listed but I couldn't figure out how to bring them over into the Feeds and Speeds page. I just wanted to experiment with those Chamfer tools already in the data base in an attempt to figure out what I'm doing wrong when I enter the data for my 3/8" 4flute Chamfer tool.
The speeds and feeds I'm getting are 10,000 speed and .09 feeds. For a tool that's spinning at 10-K-RPMs and taking such light cuts it seems like the feed should be a lot more than .09. I know I'm doing something wrong. I just can't figure out what exactly.
In my CAM software I'm able to assign a specific depth as the actual contact position of the angle of the cutting flutes to my part but I'm not sure how to enter that depth; or if it even translates into the HSMA sofware. I tried varying the DOC in the HSMA feeds and speeds page but it doesn't seem to effect any changes.
Can you help me figure this out. Since being gifted with this feeds and speeds software I've been able to figure out the features that have helped me speed up the machining efforts of my weaker Tormach hobby mill but there are times like now when I just can't figure it out without some help.
