automatically. Individual machining steps can
be simulated separately or used as a starting
point for the simulation. The simulation
checks each machining operation before the
machine set-up, which means that the
hyperMILL Virtual Machining Center delivers
maximum processing safety. And there is a
release process for NC programs, Bramb
In addition to efficient simulation, the
hyperMILL Virtual Machining Center includes
comprehensive analysis functions. Every
machining situation can be examined in
detail. The best-fit function makes it possible
to check the machining area reliably. It
automatically calculates the optimal
placement of the component for the available
workspace. In the real world, this can often
prevent time-consuming machine
Various technical charts provide valuable
information about the quality of the machine
run. The traverse movements of the different
axes, feed rates and spindle speed are
visible to the CNC programmer at all times.
This helps to prevent errors and inefficient
operations. The analysis functions therefore
provide even more safety and transparency.
A further module offered as part of this
new and safe process for NC code creation is
the hyperMILL Virtual Machining Optimizer
module. This automatically finds the
technically best, collision-checked tool
position with efficient traverse movements for
Says the company: “There are many ways
to position the tool in multi-axis machining.
The quality and efficiency of the milling
operation is largely dependent on the
solution that is selected. Due to the
complexity of multi-axis machining, it is often
not possible to find the optimal overall
solution when setting the axis position
hyperMILL Virtual Machining Optimizer
always finds the best collision-free tool
position automatically and during the postprocessor
run, the company claims. It takes
account of kinematic properties and userspecific
collision avoidance requirements.
This avoids programming errors or
subsequent editing of the machining program.
It analyses entire machining sequences
and not just individual operations.
Accordingly, the Optimizer always selects the

The new and highly effi cient hyperMILL Virtual Machining Center simulation solution
ideal solution for machining the entire
sequence together, within the existing
machine limits. In this way, it achieves its
objective of avoiding time-consuming
repositioning and retract movements.
Guaranteed optimal, collision-free and
efficient machining is the outcome.
The final element in the process is
hyperMILL Connected Machining. This
module ensures seamless networking
between the CAM software and machine. One
of the highlights is the bidirectional exchange
of data with the machine controller, which
means that data can be sent to, and also
received from, the machine. As a result, the
actual machining process is available to the
user in the simulation – in real time.
hyperMILL Connected Machining ensures that
the manufacturing and simulation are
perfectly synchronised. Machining operations
on the CNC machine tool are easily controlled
via a laptop.
The machine run will only start if the data
matches and the collision check has been
carried out successfully. If this is not the
case, the hyperMILL Connected Machining
safety mechanism prevents the transfer of
NC programs to the machine and also stops
the machine from starting. An additional
safety feature is the fact that NC programs
are loaded directly into the memory of the
controller, which stops programs from being
mixed up and protects them against
unauthorised access. ■
Slam dunk demo at IMTS
This basketball hoop that was successfully machined using hyperMILL
5-axis programming was displayed during the IMTS exhibition, where
visitors were able to test their ‘hoop shooting skills’. Machined on a
Grob (https://is.gd/ecexok) G350 5-axis machining centre using conical
ball barrel cutters from OSG (https://is.gd/uxujuc) to machine the
basketball hoop, the starting point was a 81 kg block of aluminium.
Using a 320 mm cutting tool length, the fi nished basketball hoop was
milled to 565 g, a 99.3% material reduction. The application showcases hyperMILL’s
high performance capability for complex 5-axis machining, including milling deep
pockets and fi nishing curved shapes. Superior collision control enables a long cutting
tool to cut in extremely tight contours. The outer regions were machined via hyperMILL
MAXX Machining roughing, applied with a 5-axis shape-offset roughing process.
The hoop has an intricate design that was machined to the fi nest levels of detail.
