HSMWorks Manual Tutorial 1 - 2D Machining

1

Tutorial 1 - 2D Machining

In this tutorial you will learn how to machine the part above through the
following steps:

• Contouring

• Pocketing

• Drilling

• Tapping

• Post processing

Before proceeding, please open the part Tutorial1.SLDPRT into
HSMWorks, by choosing Open from the File menu, and then browsing
to the file.

The files used in this manual can be found in the examples folder in
the folder where HSMWorks is installed.
Typically, this is something like
C:\Program Files\HSMWorks\examples\

HSMWorks Manual Contouring

Contouring

We want to run a contouring toolpath along the outer edges of the part.

• Click 2D Contour on the HSMWorks toolbar or select it from the
HSMWorks, Toolpaths menu.

This creates a new operation, and opens the property manager where you
can edit the individual parameters controlling the toolpath, as well as
selecting the actual geometry to machine.

The property page is divided into a number of groups, and in this tutorial we
will go through each one by one, changing the necessary settings in each
group as we go along.

Tool View
The Tool View group allows you to select a different orientation to machine
from.


The tool view of the active operation is always
shown on the model like the coordinate
system to the right.

Note the color of the axes:

• X-axis is Red.

• Y-axis is Green.

• Z-axis is Blue.

You always need to have your Z-axis pointing upwards from the areas
you want to machine since the tool rotates about the Z-axis on the
machine tool with the tool tip pointing in negative Z.

Most of the time, it is also an advantage to have the origin at the top of
the model (or stock) such that positive Z-values are always in the air.

Job settings

Go to the HSMWorks operations manager by clicking on the
Machining Operations tab:

Right click on Tutorial4 Operation(s) and select New Job.

Set the Working Coordinate System (WCS)

When creating a new job, the default WCS can often be used.

The default WCS depends on the the design of the assembly or part. In
this case HSMWorks detects that a single coordinate system exists and
uses that for the default WCS.

In the following section, we show how to manually select a coordinate
system for the WCS even though the default could be used. This
allows you to change the WCS if you are not happy with the default
selection, or if you have created more than one coordinate system
feature.

Scroll down to the group Working Coordinate System (WCS).

In the drop down menu Tool view selection, make sure that Use
Coordinate System is chosen.

Make sure that the WCS origin field is active by clicking on it.

In the model window click the in front of Tutorial4 to expand
the Assembly tree.

Make sure that the Coordinate System1 feature is selected:

Define the stock

Defining the stock on a simple example like this is not strictly
necessary since by default HSMWorks uses an Automatic stock as the
bounding box of the model.

Defining the stock to match that actually used on the machine does,
however, make the solid verification more accurate.

On machining assemblies with multiple parts and/or fixtures in the
assembly, this exercise will prove important.

• Scroll up to the Stock.

• From the drop down menu select Automatic.

• Set the values Offset X and Offset Y to 0mm and Offset Z to 1mm.

Define the surfaces

Again, the defaults can be used, but we perform the selection manually
to show how to correctly define surfaces in an assembly with more
than one component.

• Scroll down to the group Surface.

• Click the selection field to set the selection focus.

HSMWorks Manual Chamfering

133

2D Contour
When choosing a Chamfer Mill as the tool, the Chamfer option was
automatically enabled, thereby showing the chamfering parameters
Chamfer Width and Chamfer Tip Offset.

Since we have chosen an edge on an actual chamfer feature in the model we
don't have to set the Chamfer Width, but we do need to set the Chamfer Tip
Offset so that the tool tip is not coincident with the lower edge of the
chamfer:

• Set Chamfer Tip Offset:

0.25mm

Start Calculation

• Click at the top of the property manager.

The toolpath should look like in the picture below:

This completes the toolpaths for this part and you can now simulate and
post-process the result.

HSMWorks Manual Post Processing

Post Processing

We are ready to postproces all toolpaths in order to make the NC-code
which can be used by the machine tool.

• Right-click on Job in the operation manager.

• Select Post Process (All).

• From the pulldown Post processor configuration select
heidenhain.cps - Generic Heidenhain

• Select an output folder of your choice.

• Start the post processor by clicking Post. By default the post
processed file will be loaded into HSMWorks Edit.

By default the post processed file will be opened in HSMWorks Edit
which allows you to inpect the generated NC-code as well as transferring it
to your machine.

Congratulations! You have completed this tutorial.
