Lathe Material Weight
The Lathe Material weight function will calculate the weight of the part using the Solids feature.
How to use for finding the weight of the forging and the weight of the finished part:
1. Draw the outside shape of the part.
Here we have drawing of the forging shape and the drawing of the finished part inside it. Preferably on different layers so we can turn them on and off.
Set Layer to Solid layer and draw points around the outline.
Make sure the solid layer is set to the layer you are using for the points.
Turn on Solids. Alt-F3
On the Utilities menu, choose Lathe Mat Weight.
Do the same on the finish part except on a different layer so we can turn off the points.
The larger the part is on the screen, the more accurate the result will be.
If drawing units are in Millimeters instead of inches set the unit on the Configuration - Time page.
Then you can subtract one result from the other and estimate how much weight in chips you will end up with.
List of materials in the dropdown list:
The materials list is a user defined list that is loaded into the dropdown at startup.
It is a text file named "materials.ini" in the form of
Aluminum 4028 SP=0.101
Titanium 4902 S=0.163
Each line has first the name of the material, then an equal sign, then the material density, which is in pounds per cubic inch.
The file is in the User Data Folder
