Geometry Creation
Setting Up Geometry
When working with multiple-spindle parts, geometry must be set up for each spindle. Each spindle has its own set of coordinate systems that define the primary planes you may work in, based on the options installed. There are several different methods to prepare geometry for Multi-Task Machining. The rule is that the geometry must be properly positioned relative to the spindle it will be used on. This is best achieved by using the coordinate systems associated with a specific spindle. The methods include:
- Create one finished shape at Spindle 1. Duplicate and move the geometry to the other spindles. Just as in the Lathe module, you can usually define your roughing operations from the final shape geometry.
- Create different shapes for each spindle at Spindle 1 then move the geometry to the other spindles.
- Create the shapes at the spindle you intend to use the shape on.
- Any combination of the above.
One of the things you do not need to be concerned about is defining a stock condition for each spindle with geometry. While you can make a non-cylindrical stock body (as documented in the Lathe manual), such as a casting for the initial stock on the primary spindle, all sub spindles calculate the stock remaining from previous operations and generate the condition of the stock as it exists when transferred to a spindle in Cut Part Rendering. This is illustrated below. The image shows the condition of the stock on Spindle 1 after being machined and how Spindle 2 will look when Cut Part Rendering begins on it. This includes milling operations. This feature is automatic and fully associative. It establishes the Material Only starting condition for machining on a spindle.
