Virtual prototyping (VP) is an area where huge advances have been made. As gear and transmission systems, and the methods of their production, become more complex and more interdependent, finding ways to use VP across the entire development process—from the initial design, through analysis, right up to manufacturing—ultimately means gaining a better understanding of system performance and efficiency.
Applying their Materials by Design methodologies, QuesTek Innovations has expanded their ICME framework under US Army Small Business Innovation Research (SBIR) funding to adapt their high-performance Ferrium C64 gear steel to AM processes to demonstrate printability across multiple systems, achieve AMS minimum tensile properties, and observe a positive response to heat treatment.
Broaching is an unusual machining process, because it has the feed built into the tool, which effectively makes it a collection of single-point cutting tools arrayed in a sequence. Analogous to the multiple passes of a shaper, a relatively new class of CNC tooling and programming allows broaching operations to be done without the need for a second operation, thus greatly increasingly quality control and reducing time, space and cost.
