Slide Cores versus Machining
The casting design engineer chooses the optimal production approach for each feature, meeting tolerance and dimension requirements with acceptable final production costs.

The drawing to the right shows the two intersecting holes in the upper accelerator. 

It can be produced --

Accelerator

Upper Accelerator Fixture

  • by two slide cores in the mold and a finish machine step

  • by a two step (rough & finish) machining process
Which fabrication method (Slide Cores or Machining) should be used for the intersecting holes?
