• 2.5D Milling
InventorCAM provides both interactive and automated powerful 2.5D
milling operations on Inventor models. InventorCAM offers one of the
best pocketing algorithms in the market. Full tool path control and powerful
algorithms ensure that the user can manufacture the way he needs to.
Operations can be easily re-ordered, rotated, mirrored, etc. InventorCAM’s
automatic feature-recognition and machining module automates the
manufacturing of parts with multiple drills and complex holes.
All your needs for successful production machining are provided directly
inside Inventor with an easy and straightforward interface. InventorCAM is
successfullyusedinproductionenvironmentsbythousandsof manufacturing
companies and job shops.
• 3D Milling
InventorCAM’s 3D Milling can be used both for prismatic parts and for
complex 3D models. For prismatic parts InventorCAM analyzes the model
and automatically recognizes pockets and profiles to be machined using
Z-constant machining strategies. For complex 3D models, InventorCAM
offers powerful 3D machining, including integrated rest material options.

6
• 3+2 Axis Multi-Sided Machining
With InventorCAM, programming and machining of multi-sided parts on
4- and 5-Axis machining centers is efficient and profitable. InventorCAM
is an industry leader in this type of machining. InventorCAM rotates the
Inventor model to the user-defined machining planes and automatically
calculates all necessary shifts and tilts for the 3D machining coordinate
systems.
InventorCAM enables flexible set-ups and reduces the need for special
clamping jigs. You can define your 2.5D and 3D machining operations on any
face and check them using InventorCAM’s advanced tool path verification.
The output is ready-to-run programs for your 4/5-axis CNC-machine.
• Simultaneous 5-Axis Machining
Simultaneous 5-axis machining is becoming more and more popular due to
the need for reduced machining times, better surface finish and improved
life span of tools. InventorCAM utilizes all the advantages of Simultaneous
5-Axis machining and together with collision control and machine
simulation, provides a solid base for your 5-axis solution.

7
InventorCAM provides intelligent and powerful 5-axis machining strategies,
including swarfing and trimming, for machining of complex geometry parts
including mold cores and cavities, aerospace parts, cutting tools, cylinder
heads, turbine blades and impellers. InventorCAM provides a realistic
simulation of the complete machine tool, enabling collision checking
between the tool and the machine components.
• High Speed Machining (HSM) Module
InventorCAM HSM is a very powerful and market-proven high-speed-
machining module (HSM) for molds, tools and dies and complex 3D
parts. The HSM module offers unique machining and linking strategies for
generating high-speed toolpaths.
InventorCAM’s HSM module smooths the paths of both cutting moves and
retracts wherever possible to maintain a continuous machine tool motion–
an essential requirement for maintaining higher feedrates and eliminating
dwelling.
With InventorCAM HSM module, retracts to high Z levels are kept to a
minimum. Angled where possible, smoothed by arcs, retracts do not go any
higher than necessary – thus minimizing aircutting and reducing machining
time.
Any HSM 3D machining strategy can be controlled by specifying the
surface slope-angle to be machined or by specifying the machining
boundary. InventorCAM HSM module provides a comprehensive set of
boundary creation tools, including Silhouette boundaries, Cutter Contact
Area boundaries, Shallow boundaries, Theoretical Rest Area boundaries,
Rest Area boundaries and User-defined boundaries.
InventorCAM HSM module is a powerful solution for all users who demand
advanced high speed machining capabilities. It can also be used to improve
the productivity of older CNC’s with reduced air-cutting and smoothing
arcs that maintain continuous machine tool motion.

8
The result of HSM is an efficient, smooth, and gouge-free tool path. This
translates to increased surface quality, less wear on your cutters, and a longer
life for your machine tools.
With demands for ever-shorter lead and production times, lower costs
and improved quality, High Speed Machining (HSM) is a must in today’s
machine shops.
• Turning and Mill-Turn

A powerful integrated Mill-Turn capability enables the turning and milling
operations to be programmed in the same environment. Access to the
complete 2.5-5 axis milling is available. InventorCAM provides support for
up to 5-Axis (XYZCB) Turn-Mill CNC machines including back-spindle
operations.
• 2/4 Axis Wire-EDM
InventorCAM Wire EDM handles profiles and tapers with constant and
variable angles, as well as 4-axis contours. InventorCAM’s intelligent
algorithms prevent the falling of material pieces by automatic pocket
processing. InventorCAM provides full user control of stop-points and of
wire cutting conditions at any point of the profile or taper.

These Pocket operations perform the roughing of the complex pocket
formed by the internal faces of the part. An end mill tool of Ø10 is used.
