What is EdgeCAM Turning?

The EdgeCAM Turning module allows you to use fixed tooling to generate toolpaths from turned geometry.

The module permits both Two Axis and Four Axis Turning.

Fixed tool types of many styles can be used, and include:

Right, left, and neutral handed external turn

Right, neutral, and back boring internal turn

Grooving and parting tools

Threading

Drills

Taps

Standard Two Axis Cycles

Rough Turn

In addition, any Two Axis cycle may be synchronised with another, provided that they are being performed

on separate turrets.

Driven Tools on a Turning Centre

EdgeCAM supports milling and drilling of 2D geometry on a turned part in three modes:

Axial Milling

Radial Milling

Y Axis Milling (Planar)

Swept Profiles

2D turned profiles may be swept to represent the turned component in three dimensions.

Creating a Profile from Existing Geometry

The EdgeCAM Turning module allows you to use fixed tooling to generate toolpaths from turned geometry.

The module permits both Two Axis and Four Axis Turning.

Fixed tool types of many styles can be used, and include:

Smooth – If this box is checked then arcs and lines to be fitted to the generated profile, also the resultant

profile is a continuous entity.

Tolerance – Used by the smoothing process to determine the accuracy of the fit.

Right, neutral, and back boring internal turn

Grooving and parting tools

Select any entities to be considered during this process (usually using the window icon). You can then

deselect any entities that are not to be swept. Note: the profile considers the horizontal axis of the active

CPL to be the axis of revolution.

The turned envelope can be rough turned in preparation for any milling operations that will complete the

process. The turned envelope represents the minimum boundary for turning, without removing stock

required by the milling operations for forming geometric features.

Rough turning is often faster than milling operations at stock removal, and tool costs are generally lower.

In addition, any Two Axis cycle may be synchronised with another, provided that they are being performed

on separate turrets.

Swept Profiles

2D turned profiles may be swept to represent the turned component in three dimensions.

What is EdgeCAM Turning?

Use the Turned Envelope (Geometry menu) command in Design mode to create a profile from existing

geometry. This feature is used to generate a 2D profile, which represents the total swept area when the

component is revolved through 360° about the centre of revolution.

Right, left, and neutral handed external turn

Sweeping the Component Graphics

Although you may have defined the profile geometry, you may want to get some idea of what the resulting

turned part looks like.

Use the Design mode command Sweep (View menu) to draw repeats of the selected profile at regular

intervals about the Z axis (or any other specified axis). These repeats and related geometry are called

“swept graphics”.

Right, left, and neutral handed external turn

These parameters are important in creating swept graphics:

End Angle – Specifies the angle at which the last repeat appears.

Threading

Drills

Repeats – Specifies the number of repeats to appear in a 360° rotation about the selected axis.

Circles – Check the box to create circles at the ends of the swept entities.

Taps

Views – Specifies the ports in which the swept graphics appear.

CPL – Specifies the axis (from all available CPLs) about which the profile is swept.

What is EdgeCAM Turning?

A billet represents the raw stock (casting, forging or previously machined component) to be machined into

the part.

Turn cycles that use stock include Rough Turn, Rough Groove and Rough Side Groove. The billet tells the

cycle where cuts need to be made to remove material.

As with other types of stock, you can create billets with the Stock/Fixture command:

Right, left, and neutral handed external turn

Right, neutral, and back boring internal turn

Grooving and parting tools

In the Stock dialog, make sure that Shape is set to Turn Billet .

When you come to digitise, you will be prompted for a 2D Profile to define the billet.

You can now digitise the billet profile when specifying cycle geometry. (Note that you need to digitise the

end point of the profile.)

However you do not necessarily need pre-defined billets. At the 'Digitise billet or cycle start position' prompt,

you could digitise:

Taps

Standard Two Axis Cycles

Rough Turn

An existing toolpath. The cycle then only removes the material left by the previous machining. See

Using Dynamic Billeting for more information.

Finish Turn

Rough Groove

Finish Groove

A turn feature. This would typically be derived from a separate solid model, representing the billet.

Note that for this digitise, you need to hold down the Ctrl key while clicking on the feature.

Fixed tool types of many styles can be used, and include:

A rough turning operation may leave material where the geometry of the tool insert will not allow full cutting

to occur.

For example, a right hand tool may leave material that will have to be removed by a left hand tool

afterwards:

Using Dynamic Billeting

In addition to the starting billet, EdgeCAM allows previous toolpaths to be used to reduce the amount of air

cutting. This is termed ‘Dynamic Billet’, because the material condition can change if previous tool paths are

edited.

Right, left, and neutral handed external turn

The toolpath created by the right hand tool can be selected as a dynamic billet when using the left hand

tool.
