1. Introductio
Basic Concepts1.2
Every manufacturing project in SolidCAM contains the following data:
CAM-Part The CAM-Part denes the general data of the workpiece. This includes thmodel name, the coordinate system position, tool options, CNC-controller, etc.
Geometry By selecting Edges, Curves, Surfaces or Solids, dene whatand whereyoare going to machine. This geometry is associated with the native SolidWorks model.
Operation An Operation is a single machining step in SolidCAM. Technology, Tooparameters and Strategies are dened in the Operation. In short, Operation means how
you want to machine.
Process Overview1.3
The major stages of the SolidCAM manufacturing project creation process are the following:
CAM-Part definition
This stage includes the denition of the global parameters of the ManufacturinProject (CAM-Part). You have to dene a number of Coordinate Systems that describ
the positioning of the part on the CNC-machine.
Optionally, you can dene the Stock model and the Target model to be used for threst material calculation. The Stock model describes the initial state of the workpiec
that has to be machined. The Target model describes the one that has to be reache
after the machining. After every operation, SolidCAM calculates how much materia
was actually removed from the CAM-Part and how much material remains unmachine
(rest material). The rest material information enables SolidCAM to automaticalloptimize the tool path and avoid the air cutting.
Operations definition
SolidCAM enables you to dene a number of milling operations. During an operatiodenition you have to select the Geometry, choose the tool from the Part Tool tabl(or dene a new one), dene a machining strategy and a number of technologicaparameters.

The CAM-Part denition process includes the following stages:
CAM-Part creation. At this stage, you have to dene the CAM-Part name and location.SolidCAM denes the necessary system les and a folder to allocate the place to storeSolidCAM data.
CNC-controller definition. Choosing a CNC-controller is a necessary step. The controllertype inuences the Coordinate System denition and the Geometry denition.
Coordinate System definition. You have to dene the Coordinate System the origin forall machining operations of the CAM-Part.
Stock model definition. SolidCAM enables you to dene the stock model that describesthe initial state of the workpiece to be machined.
Target model definition. SolidCAM enables you to dene the model of the part in its nalstate after the machining.

2. CAM-Part Definitio
Exercise #1: CAM-Part Definition
This exercise illustrates the CAM-Part denition process in SolidCAM. In this exercise, you have tcreate the CAM-Part for the guide model displayed below and dene the Coordinate System, th
Stock model and the Target model that are necessary for the part machining. The CAM-Part will b
used in the exercises further on.
When you start to program a CAM-Part, you have to decide wha
workpiece you are going to use. This decision determines th
number and the type of operations that are used to reach the npart shape.
In this exercise, the block workpiece is used. The block dimensionsare 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 CNC-machine you are going to use (3-, 4- or5-axis). In this exercise, a 3-axis CNC-machine ischosen for the machining. With a CNC-machine
of this type, all the required faces of the guide part
can be machined using a single positioning.

Model name
This eld shows the name and location of the SolidWorks desigmodel that you are using for the CAM-Part denition. The name i
by default, the name of the active SolidWorks document. With thBrowsebutton you can choose any other SolidWorks document t
dene the CAM-Part. In this case, the chosen SolidWorks documenis loaded into SolidWorks.
Every time the CAM-Part is opened, SolidCAM
automatically checks the correspondence of the dates o
the CAM-Part and the original SolidWorks design mode
When the date of the original SolidWorks model is late
than the date of the CAM-Part creation, this means tha
the SolidWorks original model has been updated. Yocan then replace the SolidWorks design model on whic
the CAM-Part is based with the updated SolidWork
design model.

2. CAM-Part Definitio
SolidCAM copies the original SolidWorks model to the Millin
subdirectory and creates a SolidWorks assembly that has the sam
name as the CAM-Part (Milling.sldasm). There are two componentin this assembly:
DesignModel.sldprt a copy of the SolidWorks model le.
CAM.sldprt a le that contains SolidCAM Coordinate System datand geometry data.
The SolidCAM CAM-Part uses the assembly environment o
SolidWorks. This enables you to create auxiliary geometries (e.gsketches) without making changes in the original design model. Yocan also insert some additional components into the assembly lsuch as stock model, CNC-machine table, clamping and other toolin
elements.
Choose the CNC-Controller4.
Select the CNC-machine controller. Click on the arrow in the CNC-Controllerarea t
display the list of post-processors installed on your system.
In this exercise, use a 3-Axis CNC-machine with the
Awea1000-FanucCNC-controller. Choose the Awea1000-
FanucCNC-controller from the list.
Start the Coordinate System definition5.
Click on the Define button in the Coordinate System area
to dene the Machine Coordinate System.
To complete the CAM-Part denition, you need to dene the MachinCoordinate System.
The Machine Coordinate System denes the origin for all machininoperations of the CAM-Part. It corresponds with the built-i
controller functions.

You can dene the Coordinate System origin position and axesorientation by selecting model faces, vertices, edges or the SolidWorks
coordinate system. The geometry for the machining can also be
dened directly on the solid model.
The Z-direction of the Machine
Coordinate System is parallel tothe revolution axis of the tool.
In SolidCAM, the tool approaches
from the positive direction of the
Z-axis (like on a vertical CNC-machine).
For 3-Axis CNC milling machines, each Machine Coordinate
System means separate clamping. If you need to machine the part
from different sides, use several Machine Coordinate Systems withthe Z-axis oriented normally to the machined sides.

In this exercise, it is enough to deneone Machine Coordinate System with
the Z-axis oriented upwards.
Such coordinate system enables you
to machine the part with a single
clamping.
The CoordSys dialog box enables you to dene the CoordinateSystem location and the orientation of the axes.
You can dene the Coordinate System origin position and
axes orientation by selecting the model faces, vertices, edges orSolidWorks Coordinate Systems.
SolidCAM enables you to dene the CoordSysusing the following methods:
Select Face
This method enables you to dene a new
CoordSys by selecting a face. The face canbe planar or cylindrical/conical. For planar
faces, SolidCAM denes CoordSys with theZ-axis normal to the face. For cylindrical or
conical faces, the Z-axis of the CoordSys is
coincident with the axis of revolution of the
specied cylindrical/conical surface.

Select Coordinate System
This method enables you to choose the SolidWorks Coordinate System
dened in the design model le as the CoordSys. The CoordSysorigin and axes orientation are the same as in the original SolidWorks
Coordinate System.
Normal to current view
This option enables you to dene the Coordinate System with theZ-axis normal to the model view you are facing on your screen. The
CoordSys origin will lie in the origin of the SolidWorks Coordinate
System, and the Z-axis will be directed normally to the chosen view
of the model.
Select the model face6.
With the Select Face method chosen, click on the
model face as shown.
The CoordSys origin is automatically dened in thecorner of the model box. The Z-axis of the CoordSys

The Clearance level is the Z-level to which the tool moves rapidly
from one operation to another (in case the tool does not change).
The Part upper leveldenes the height of the upper surface of thepart to be milled.
ThePart lower level
denes the lower surface level of the part to bemilled.
The Tool Z-levelparameter denes the height to which the tool movesbefore the rotation of the 4/5 axes to avoid collision between the tool
and the workpiece. This level is related to the CoordSys position and
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 leveloption 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
the FeatureManagerDesign tree.

SolidCAM offers you the following types of 2.5D Milling operations:
In SolidCAM, an operation is a single machining step. A workpiece is usually manufactured using
several machining steps and technologies. For each of these steps you can dene a separate operation.An operation can be very complex, but it always uses one tool, one major geometry and executesone machining type, e.g. Prole Milling or Drilling. You can edit any single machining operation,change the operation sequence and generate the GCode, combining and splitting the operation list
of your CAM-Part.
The Machining Geometry has to be dened for each operation. The Geometry prompts SolidCAMwhat and where you want to machine.
A Geometry for Prole, Pocket, Contour 3D, Slot and T-Slot operations consists of anumber of chains. Chain geometries are dened by selecting the following entities: edgesof models, 2D curves, 3D curves, circles, lines and splines. Each chain is composed of
one or more entities and denes an open or closed contour.
A Geometry for Face Milling operations can be dened by selecting solid models, facesor chains of model elements.
A Geometry for Drilling operations consists of one or more points (drilling centers) thatcan be dened by a number of methods directly on the solid model.
A Geometry for Drill Recognition and Pocket Recognition operations is determinedautomatically by SolidCAM Automatic Feature Recognition functionality.

3. SolidCAM 2.5D Operation
Face Milling Operation
This operation enables you to machine large at surfaces with facemill tools.
Profile Operation
You can mill on or along a contour. The prole geometry canbe open or closed. In prole milling you can optionally use
tool radius compensation to the right or to the left side of the
geometry. SolidCAM offers two types of proling:
Milling a single prole to the specied constant orvariable depth in one step or in several user-deneddown steps.
Concentric proles to the specied constant or variable depth; this type of prolingenerates several concentric proles that start from the dened clear offset distance from
the prole, and nish on the prole geometry, thus clearing the area around the prole t
a constant depth.
Pocket Operation
In pocket milling, you have to remove material from the interior of
a closed geometry. SolidCAM offers two types of pocketing:
When a prole geometry consists of one or moreproles and none of them are enclosed or intersect with
one another, each is milled as a separate pocket withoutislands.
When a prole geometry consists of several proles, anyprole that is enclosed or intersects with another prole istreated as an island. You can dene an unlimited numberof islands within a single pocket.

Prole roughing is performed in constant Z-passes. The Step dowparameter denes the distance between each two successive Z-level
Set the Stepdownto 3. With this value, SolidCAM performs three cuts at the followinZ-levels: -3, -6,-9; the last cut is performed at the Z-level dened by Profile depth: -10
The distance between the Z-levels of the last cut and the preceding cut is smaller tha
that between the previous cuts, because the machining depth value is not divisibl
exactly by the Step downvalue.
In this operation, use the Equal step downoption to keep an equal distance betwee
all Z-levels.
Equal step down
This option enables you to
perform all cuts at an equal
Z-level distance one from the
