why do we leave Tags when we do CNC machinig
(OP)
Hi All
watching this Video, I noticed the guy is leaving tags on the profile , and he explained this is to avoid the part to be cut off completely during machining , why do we do that ? why should we not cut the part off completely ?

Please provide a link.
Thanks.
Conjecturally, if the workpiece is not completely finished in one operation,
and for example needs to be set up in another machine for a subsequent operation,
it can make sense to leave some portion of the feature by which the part
was first located in a fixture, so that the subsequent operations'
fixtures use the same feature for location. When the part is
otherwise complete, said tags or whatever can be removed by
abrasive machining, or perhaps just snapped off, or even left
on the finished part if they don't interfere with any function.

B.E.
You are judged not by what you know, but by what you can do.

Vacuum fixtures can also be used to avoid tabs.

If there is a way to clamp it for tab removal then yes you can fully machine it then. Also low melting point alloys can be used to hold the part as well.
