Hi, and another very warm welcome from all of us to all of you.
You’ve reached the SmartCAMcnc
Blog. We created our blog to primarily inform about this-or-that aspect
of our CAM software / CNC Programming software, but we also post other information that
we hope you will find interesting and informative.
We intend to provide a mixture of
information here on our blog that will be of interest to our valued existing
customers and potential new SmartCAM users alike.
We just know that this post will be
of interest to everyone who understands CAM. It has a technical bias, where I’d
like to provide information to you about one of the most powerful yet possibly underused
features of SmartCAM Milling applications:
SmartCAM Regions
Part 1
Rest Mill Regions
SmartCAM
Region technology is
applied in several use cases in SmartCAM. In this first part of our discussion about
Regions
we’ll focus on how they are used for Rest Milling functionality; creating regions of
material left-over after roughing that can be used as inputs to a Region Roughing
Process to generate rest milling toolpath using smaller diameter
tooling.
An extract from our reference
documentation can set the scene for us:
Use Rest Output to create 2D rest mill regions representing uncut material left
behind by the roughing tool. The rest mill regions can then be cut with a
smaller tool using the Region Rough process and a Part Offset toolpath.
SmartCAM
Rest Milling
We’ve
roughed out the pocket on the model below using a 1 inch diameter tool in the Wireframe
Pocket Process.
The
Process includes options to generate the rest-regions needing to be machined, in
this case by a finishing or semi-finishing tool of 1/2 inch diameter.
I’ll
focus on just one area of the model, and remove the holes from the view just
for clarity.
The picture below shows the Pocket Process Parameters panel and the
settings I have used to control Rest Mill Region output.
The
rest regions required for the smaller tool are automatically generated on my
preferred CAD
Layer, 7, and as a Named Group called ‘Restmill Regions’ when my
options are used. The rest mill region results for the sample model are shown
in blue:
Rest
Machining
The
Rest Roughing process can then be used to easily
generate rest region clean-up toolpaths. The image below shows the roughing toolpath
in dark blue and the rest-machining process toolpaths in red:
And
I have verified the toolpaths using SmartCAM ShowCut
verification. The effect of the roughing and rest mill toolpaths are easiest to
see in the plan view:
That completes the first part of my short overview of
the SmartCAM Region tools. With the use case that
we have just studied, you have seen that they can provide significant
time-savings when rest-machining regions are unavoidable and need to be
processed.
More
later
We
intend to cover another use of SmartCAM Region technology in an additional article
soon; to create machining boundaries that can be comprised of wholly closed or
open regions.
Keep in
touch
Check
back with us soon, won’t you. If you’re interested in speaking to us about
SmartCAM then contact us using the link to our email that we’ve included below.
We hope you have found this detail of our SmartCAM CAM software interesting and helpful.
Have a great day,
