1.1 Internal Post-Processor (IPP) and GPPTool Enhancements

SolidCAM2007 R11.1 provides you with the following enhancements in Internal

post-processor (IPP) and GPPTool:

A new procedure manager that enables you more powerful support for

post-processing.

Support of relative G-code for CNC machines that work in relative G91

mode (pre-processor parameter: relative_gcode = Y):

Formerly, in order to generate the relative G-Code, it was necessary to

make modications in the GPP le. In this version, it is the responsibility

of the internal post-processor to produce the relative G-Code.

Information about the rst tool position in the next operation, relative

to the Machine Coordinate System in @chng_tooland @call, is provided

by the new GPPL parameters:xhnext, yhnext, zhnext (in case the pre-

processor parameter pos_to_coordis set toY).

A new last_procedure_number parameter in GPPTool: this parameter

contains the largest number of procedure in the generated G-code.

A new P-code for height compensation: @compensation_h:When the compensation changes, the generated G-code provides a new

item compensation_h, with theoffset_height parameter, that contains the

data of the new tool length compensation.

New GPP parameters in @start_of_jobfor HSM: feed_rapid, feed_ramp_

down, feed_ramp_up:

Based on these parameters, the Link Up,Link Downand Rapidvalues in

the Feed Rateeld of the Tool page of the HSM Operationdialog box are

generated in the G-code for the respective operation.

Support of new tool types in @chng_tool that are displayed in the GPPle.

1.2 CNC Machine Type Support

SolidCAM2007 R11.1 provides you with a new CNC-Machine kinematics type

XY, where the X-axis is the rst rotation axis and the Y-axis is the second rotation

axis. There is no rotation dened around the Z-axis.

To choose this type, use the pre-processor parameter _5x_rotary_axes=XY. The

rotation angles of the machine are calculated according to the value of this

parameter. When _5x_rotary_axesis set to XY, the post-processor is notied thatthe machine does not have a rotation axis capable of rotating about the Z-axis.

This being the case, the rotation around the Z-axis is clamped to zero and the

resulting rotations are calculated around the X- and Y-axes such that the XY-plane

is positioned normal to the tool axis.

2.1 Boundaries Processing

SolidCAM2007 R11.1 provides you with improvements related to the boundaries

processing algorithm.

When you change the position of the Coordinate System in a Part, the boundaries

for the HSM Operationmust be redened accordingly. If you do not redene the

boundaries and calculate the Operation, you will see during the simulation that the

tool works on another surface instead of the one you intended to machine.

To avoid such errors in the current version of SolidCAM, saving and calculating of

the Operation, after the Coordinate System has been edited, are unavailable until

the boundaries are redened. When you click on the Save & Calculatebutton, an

error message is displayed to remind you that the Constraint boundaries denitionmust be edited. The related sections on the Constraint boundariespage of the HSM

Machining Operationdialog box become empty so that you can set the parameters

anew.

2.2 Clearance Level Definition

In previous versions of SolidCAM, the Clearance level in the HSM Machining

Operation was calculated according to a formula. In order to achieve consistency in

terms of denition of this parameter in all SolidCAM machining types, Clearancelevelneeded to be determined according to the Coordinate System.

In SolidCAM2007 R11.1, this parameter is

dened as part of the Coordinate System

denition. The value you enter in theCoordSys

data dialog box appears later in the HSMMachining Operationdialog box.

If you have edited the Clearance levelvalue in the CoordSys datadialog box after

the Operation is dened and calculated, the value in the HSM Machining Operation

dialog box is updated, and the Operation must be recalculated.

In some instances, the result of this change in the Clearance leveldenition method is such that the Safety distancevalue is greater than

that of the Clearance level. In these cases, the Operations must be

edited so that the Safety distanceis below the Clearance level.

2.3 HSM Combined strategy

SolidCAM2007 R11.1 introduces the option to combine two machining strategies

in a single HSM operation. The current release offers the combination of the

Constant Z strategy supplemented with the secondary Horizontalstrategy. The nextSolidCAM release will offer two additional combined strategies that combine

Constant Z with either Linear machining or Constant StepOver machining.

To activate this strategy, do the following:

In the Technologygroup of the HSM Operationdialog box, choose

the Combine Constant Z and then the Horizontal machining item

from the submenu.

The combined two machining strategies share the Geometry,Tooland Constraint

boundaries data. The technological parameters for the passes calculation and

linking are dened separately for the Constant Z and Horizontal strategies.


15/28



15

The Constant Z Passespage denes the parameters of the Constant Z machining

strategy.

TheHorizontal Passes

page denes the parameters of the Horizontal machiningstrategy.

The following parameters, dened on the Constant Z Passespage, areautomatically assigned the same values on the Horizontal Passes page:

Thickness;

Axial thickness;

Tolerance;

Z_Top; Z_Bottom.

When these parameters are edited in the Constant Z Passespage, their

values are updated automatically in the Horizontal Passespage. But

when edited in the Horizontal Passespage, the values in the Constant Z

Passespage remain unchanged.


16/28



16

Two Linkpages, located under the Constant Z Passesand Horizontal Passespages,

dene the links relevant for each of these strategies.

In the Linkpage for Horizontal Passes,there is a new Machining order tab that enables

you to dene the order in which the Constant Z and Horizontal passes will be

performed. The default option isConstant Z first.

When the tool has nished performing the passes of the rst machining strategy,

it goes up to the Clearance level, then descends back to the machining surface to

continue with the next strategy.

3.1 Choosing Angle Pairs for 5-Axis Machining

The 5-axis vector of the tool axis can always be mapped into two different angle

pairs. During the tool path generation, SolidCAM calculates both of these two

angle pairs for each tool axis orientation, but only one of the two has to be chosenfor the G-code generation.

For all SolidCAM indexial operations, you can decide which angle pair will be used

to achieve the proper tool orientation.

In the Operation dialog box, click on the 5th Axisbutton.


19/28



19

The Tilt angle pairdialog box offers you two options to choose the angle pair:

Auto Angle Pair

When this option is chosen, the angle pair is determined automatically;

the angle pair, where the angle variation from the previous tool axisorientation is minimal, will be automatically chosen.

Other Angle Pair

Some machines can use only one of the angle pairs due to mechanicallimitations. In this case, the angle pair must be chosen according to the

Other Angle Pairsettings. This option enables you to choose the second

pair, out of the two angle pairs.

This feature is enabled for all operations when the tilt_axis_

dir_CW_CCW = Ypre-processor parameter is dened.

4.1 Tool path calculation algorithm enhancements

SolidCAM2007 R11.1 provides you with enhancements in the tool path calculation

library for Sim. 5-axis Machining.

4.2 Updated CNC-Machines Database for Machine Simulation

SolidCAM2007 R11.1 provides you with a new updated CNC-machines database

used for Machine simulation. While in the previous version the database contained

35 machines, the current version offers 60 machines, providing a wider range of

choice for Machine simulation usage.

You can update your SolidCAM Tables directory in two ways:

1. In the SolidCAM Settingsdialog box, go to the Machine Simulation

page and browse for the folder that contains the updated machine

les.

2. Copy the updated list of CNC machines to your current SolidCAM

Tables directory using the standard Windows browser.

5.1 Definition of Initial Points in Profile Operation

In SolidCAM2007 R11.1, the start point data is included in the geometry database.

Accordingly, the start point denition interface has been moved from the Operation

dialog box to the geometry denition dialog boxes.

Both the insertion point and the start point are dened as part of the geometry

denition in the Initial Pointsdialog box. This dialog box is displayed when you

click on the Definebutton in the Initial Pointsarea of the Geometry Edit dialog box.

Insertion Point

This eld enables you to dene the point where the wire is inserted into the

workpiece.

Manual

You can select the insertion point directly on the model. When you

choose this option and click on the Definebutton, the Pick insert point

dialog box is displayed with the coordinates of the point you pick.

At Normal

SolidCAM automatically denes

the insertion point, at a normal

distance from the start point of

the rst chain element. The valuein the editbox denes the normal

distance from the start point of

the chain to the insertion point.

By Hole

You can dene the insertion point in the center of one of the drilled

holes (if there are any). SolidCAM will search for holes that meet your

requirements according to the parameters you dene:

In/Out:the program will search for holes inside/outside of the closed

prole. If the geometry is not closed, this option is unavailable.

Min.diameter:enter the minimal diameter of the hole appropriate for

the wire insertion.

Max.diameter:enter the maximal diameter of the hole appropriate for

the wire insertion.

Start Point

This eld enables you to dene the point on the prole at which the wire starts

cutting the workpiece.

Manual

This option enables you to pick the start point directly on the model.

5.2 Separate Rough & Finish in Profile and Angle Operations

For multiple chains, SolidCAM2007 R11.1 enables you to decide whether to

perform the rough cutting for all the chains and then the nish cutting for all the

chains, or rough and nish cutting for each chain.

The Separate Rough & Finishcheck box is located in the Cutting technologysection

of theProfile Operation and Angle Operationdialog boxes. Selecting this check box

enables you to perform rst the rough cutting of all these chains one after another,

and then to perform the nish machining on these chains in the same order. If

this check box is not selected, the tool performs rough and nish cutting of each

chain, before moving to the next chain.

The Separate Rough & Finishcheck box is available only if the Rough

check box is selected.
