Productivity, machining efficiency and tool life are all affected dramatically by how the milling cutters is positioned on the workpiece.
In this episode we'll talk about the radial position of the cutter during machining.
In illustration number one, the cutter is on centre line and the insert is slamming into the workpiece, it's not shearing
this is the worst position possible
In the second illustration the cutter is radially engaged approximately 70%
the insert is easing itself into cut, this is the best possible position
In the third picture the cutter has only a small radial engagement, this is also a good cutter position, but...
here we need to optimize the cutting data to ensure optimized productivity
On the left side we've illustrated the best possible position
the cutter diameter is being optimized and we're generating a thick TO thin chip.
On the right side we show a small radial engagement
we're generating a thick TO thin chip, but we need to optimize the cutting data
so, we increase the feed and because of the short contact length we can also increase our cutting speed.
In summary, the cutter position has a dramatic effect on your aoverall productivity and machining efficiency:
