Open Mind hyperMILL makes complex
programming easy for Doosan Precision Engineering
Located near Nottingham City centre, Doosan
Precision Engineering specialises in CNC turning and
milling, producing parts for a wide range of sectors
spanning everything from the motorsport sector to the
food industry.
Founded in 2010, the small business has grown
rapidly by investing in a diverse range of machine tools
with multi-axis capabilities to produce parts in one-hit.
Although no relation to the Doosan machine tool
brand, the company has invested heavily in Doosan
machines from Mills CNC ( www.is.gd/ugoyob ). The ISO:
9001-certi ed company has a plant list that includes a
Doosan DNM 500 machining centre with a fourth-axis,
plus ve turning centres that include the Doosan Lynx
300M, Doosan LYNX 220LM, two Doosan LYNX 220
LSYC machines and the newest arrival, a 9-axis Doosan
MX2100ST. As a machine shop primarily conducting
turning activities, Doosan Precision Engineering isn’t
typically a facility where you would expect to nd
hyperMILL 5-axis CAM software from Open MInd
Technologies
( www.is.gd/lamemu ).
David Booth from Doosan
Precision Engineering says:
“We were spending a long time
setting-up some quite dif cult
parts with some very intricate
set-ups to cater for dif cult
features that we are
machining. This was the
reason we initially looked at
hyperMILL from Open MInd.
The prolonged set-up times
were increasing our costs and
we were losing work, some of this was going
overseas. Since we invested in hyperMILL,
we have managed to win this business back.”
Referring to how hyperMILL has positively
impacted the business, he continues:
“hyperMILL has reduced the set-up times
massively. Some parts were taking four to ve
hours to program and set, the new CAM
system has now reduced this to as little as
30 minutes in many cases. Open Mind is well
respected as an industry leader in 5-axis
milling technology, but we speci cally bought it
with turning in mind. We have one part that
was originally manufactured using grooving
tools to machine the scallop at the back,
as well as other features. Unfortunately, the
challenging material demonstrates poor swarf
control, but now we use hyperMILL we can use
a single button tool and the job comes off the
machine completely nished.
“The decision to use this single tool con guration
was decided by hyperMILL CAM software. The software
selected the best strategy to control swarf and reduce
the cycle time, which reduced massively when compared
to the previous value.”
As to programming and cycles, Booth adds:
“Essentially, our customers provide us with drawings
from most of the common le types and we feed this
into the CAM software. Providing we know and
understand the cycles, hyperMILL spits out a nished
program. That really is about as dif cult as it gets. The
code generation is straight off the CAM model and is
straightforward.
“We did the three-day training course at the Open
Mind UK facility in Bicester, which was primarily focused
upon milling with some turning aspects. However, the
system is intuitive and easy to pick up from scratch.
We have now won back all of the work that we initially
lost. hyperMILL will certainly pay for itself in a short
period of time. Of course, we also use it for all of our
milling machines. The reduction in
set-up times has been a huge bene t
to us. The ability to sit down for 20 to
30 minutes and have a nished
program is a foreign concept when we
compare it to what we used to have.
Previously, programming was taking
hours and this was a real
bottleneck.”
