1. Introduction
1.1 About this course
The goal of this course is to teach you how to use SolidCAM to machine various parts using 2.5D
Milling technologies. This course covers the basic concepts of SolidCAM 2.5D machining and
is a supplement to the system documentation and online help. Once you have developed a good
foundation in basic skills, you can refer to the online help for information on the less frequently
used options.
Course design
This course is designed around a task-based approach to training. With the guided exercises you
will learn the commands and options necessary to complete a machining task. The theoretical
explanations are embedded into these exercises to give an overview of the SolidCAM 2.5D Milling
capabilities.
Using this training book
This training book is intended to be used both in a classroom environment under the guidance of
an experienced instructor and as self-study material. It contains a number of laboratory exercises
to enable you to apply and practice the material covered by the guided exercises. The laboratory
exercises do not contain step-by-step instructions.

Windows® Vista
The screenshots in this book were made using SolidCAM 2009 integrated with SolidWorks 2009
running on Windows® Vista. If you are running on a different version of Windows, you may notice
differences in the appearance of the menus and windows. These differences do not affect the
performance of the software.

used in the exercises further on.
When you start to program a CAM-Part, you have to decide what
workpiece you are going to use. This decision determines the

In this exercise, the block workpiece is used. The block dimensions
are the same as the overall dimensions of the guide part.
With this stock, you have to machine only the steps and holes
emphasized below.
At the next stage, you have to decide on what type

of this type, all the required faces of the guide part
can be machined using a single positioning.

you have to check if it is not over the limit switch of the machine. It
is highly recommended to send the tool to the reference point or to
a point related to the reference point.
The Create planar surface at Part Lower level option enables you to
generate a transparent planar surface at the minimal Z-level of the
part so that its lower level plane is visible. This planar surface provides
you the possibility to select points that do not lie on the model entities.
It is suppressed by default and not visible until you unsuppress it in

Contour 3D Operation
This operation enables you to utilize the power of the 3D Engraving
technology for the 3D contour machining. In this operation,
SolidCAM enables you to prevent the gouging between the tool and
the 3D contour.
Thread Milling Operation
This operation enables you to generate a helical tool path for
the machining of internal and external threads with thread
mills.

In this operation, use the Equal step down option to keep an equal distance between
all Z-levels.
Equal step down
This option enables you to perform all cuts at an equal Z-level distance
one from the other. SolidCAM automatically calculates the actual step
down to keep an equal distance between all passes.
When the Equal step down check box is selected, Step down is
replaced by Max. Step down. This value is taken into account during
the calculation of the actual step down so that it is not exceeded.
With the Max. Step down value set to 3, the actual step
down is automatically calculated as the largest possible
value within the bounds of 3 so that the machining depth
can be divided exactly into equal Z-levels. Four roughing
passes will be performed at the followings Z-levels: -2.5,
-5, -7.5, -10 with the Step down of 2.5 mm.

The start point must be selected using the Data button. Enter the
ramping angle value into the Angle edit box of the Angle ramping
dialog box.
SolidCAM does not check the ramping movement against the pocket
contour. Check the tool path simulation to make sure that the tool
does not gouge the pocket walls or islands.

it machines all the material at the step down depth. Click on the Data
button to set the helical ramping parameters.

The Linear ramping follows the same rules as the Helical ramping.
The difference is that the descent is performed in a linear zigzag
fashion rather than in a circular one.
In this exercise, the Vertical strategy is used
to perform the plunging in the center of the
drilled hole.
Choose the Vertical option from the list.
In this exercise, the model contains the sketch
with the center points of the holes. This sketch
was created by the SolidWorks Hole Wizard
during the counterbore holes modelling.

DesignModel component of the CAM-Part assembly to expand it and see all features
of the model.
Expand the last feature named CBORE for M5 Hex Head Bolt1 by clicking on
the icon.
This feature is based on two sketches: one of them contains the geometry of the hole
section and the other the center points of the holes. These sketches are hidden by
default.
