In Assembly mode, if
the different parts or the multiple instances of a part comprising an assembly have
different stock materials, then for each part or instance, the correct stock material
appears.
The associated stock material appears in the
Operation Parameters dialog box on the F/S
tab for Stock material. The Feed/Speed Editor uses the
Stock material for feed/speed calculation.
In previous releases, in Mill Assembly mode, when an
assembly contained parts that had different stock materials or split part instances had
different stock materials, the feed/speed computations were often inaccurate. This
occurred because SOLIDWORKS CAM only considered the stock material assigned to the first
part listed in the Part Manager for feed/speed computation. SOLIDWORKS CAM assigned the
calculated the feed/speed values to the other parts that constituted the assembly though
they had different stock materials. This resulted in erroneous feed/speed values.
