Tormach Machining Videos
Tormach's machining videos webpage is
a bottom up approach to learning the
art and science of CNC machining - it
is learning by example. As our library
of examples expands we will add search
and indexing tools to help users find
the most appropriate example for their
needs.Conventional references such as Machinery’s Handbook approach manufacturing by explaining general theory. They explain relationships, like the relationship between surface speed, tool radius, and RPM, or establish broad guidelines, such as the machinability index. This is the top down approach; the idea is that once the larger scale concepts are understood it should be easy to formulate a solution to any individual problem. The top down approach is systematic and scientific, but it doesn’t work for everyone and cannot resolve every problem situation.
With a bottom up approach the depth of understanding is more limited, but the learning curve is far less daunting. The library of application notes is intended to provide a “quick start” method for Tormach customers learning to use their machine, as well as providing a useful public resource on the Internet.
20112 - How to Change Tools in on the PCNC

20110 - Drilling Cast Iron
Carbide spot drilling and HSS drilling in 1.5" cast iron.
20109 - Milling High Density Polyethylene
Circular interpolation milling with 0.5" HSS End Mill in 2" High Density Polyethylene.
20108 - Manufacturing Part with Multiple Tools
Three tools are used in sequence for roughing, finish cut, and then chamfer. Run time is 12 minutes, including tool change. The part is 6061 Aluminum, 3/4" thick.
20107 - Edge Milling 2" Thick 6061 Aluminum Plate
A 3/4" diameter end mill is used to radius the corners of a thick plate, then the same end mill is used on a finish cut, finishing the 2" edge in one pass.
20106 - Face Milling 1018 Steel Plate with K-Tool OCTA Mill
A 3/4" steel plate is finished on both sides. One side is a surface cut, the second side has 0.2" removed using 1.5" diameter face mill with high positive angle inserts.
20105 - Milling 1018 Steel Plate with End Mills
A 3/4" steel plate is cut to size and finished with two different end mills in the process of making an 8" chuck adaptor plate.
20104 - Three Methods for Making Large Holes in 6061
Boring, pocket circular interpolation, and spiral down interpolation are compared for accuracy and finish. Application note reviews a statistical analysis of 18 holes, 1.27" in diameter.
20103 - Surfacing 6061 Aluminum with a Fly Cutter
The surface finish and other aspects are reviewed using a variety of feeds, speeds, and depth of cut while surfacing with a fly cutter using a C2 carbide tool.
20102 - Cutting 1" Bar of 6061 Aluminum
