Rework Areas 3Dexperience DELMIA Machining

Manufacturing components often requires multiple machining operations to achieve the desired geometry, quality, and tolerance. To make programs more efficient, larger tools may be used first to remove large amount of material quickly. With this comes the potential for areas too small for the larger tool to reach to be left behind.

DELMIA Rework Areas helps manufacturers address these challenges by providing a targeted approach to machining only the areas that require attention. Rather than regenerating entire toolpaths or re-machining complete components, programmers can define specific rework zones and create focused machining operations.

Rework zone example

Rework Areas Case Study

A 20Kg plate has a recess to be machined using a closed pocket operation.

An initial pocket operation has been used to machine down to the top face of the embossed text.

Following this, a second pocketing operation has been carried out using a 16mm end mill, using the text as islands, ensuring no geometry is unintentionally removed.

As the tool is too large to reach all the small cut outs, this leaves the following geometry.

Pocket with islands

In the Prismatic Machining tab, use the dropdown next to Prismatic Machining Area and select Prismatic Rework Area.

A prompt appears asking if the operation type is pocketing. Select the green tick.

The next prompt is to enter required geometry. Instead select ESC.

From the rework area selection window, press ‘Load From’. This will allow the selection of the previous operation used and all data will be automatically inserted.

Prismatic rework area property window

Select ‘OK’ to generate the rework area feature.

Open a new pocket operation.

The first prompt is to either create a new feature or select an existing feature.

From the Manufacturing view tab, select the newly created rework area feature.

All geometry properties will automatically be entered.

The only change required is the tool to be used. This can be done on the operation tool tab.

For this case, a 1mm end mill will be used to remove any excess material around the islands.

After simulating, the rework area is machined.

Final reworked area

Rather than machining the entire component with a 16mm end mill and then repeating with a 1mm end mill, only the sections with excess material have been machined. In turn, reducing both machining time and tool wear.
