What is ISO 2768? A Guide to Tolerance Standards for CNC Machining

Determining the correct tolerances to apply to your product design can be challenging. There are natural variations amongst products that occur in mass production and you should plan for these deviations when you are applying tolerances to products. That said, you can decide how much a fabricated product can deviate from the engineering drawing dimensions […]

How to Cut CNC Machining Costs

Known for a having a hardworking and meticulous nature, Abraham Lincoln once said, “Give me six hours to chop down a tree, and I will spend the first four sharpening the axe.” While you probably aren’t reading this article for tree-felling advice, what Abe was getting at is that careful planning is important for any […]

Design Methods to Improve Torsional Rigidity

Products that are subject to a torsional load often require analysis like the analysis used for bending stiffness. The main differences are the specific material property to be used (Shear Modulus or Modulus of Rigidity) and the polar moment of inertia (which is very similar to the area moment of inertia used in bending). Torsion […]

Draft and Texture in Plastic Injection Molded Parts

It’s always a good idea to go through several drafts of any design before finalizing a part. Prototyping can help you get the right design, but you’ll need a different type of draft for a successful injection molded plastics project. In injection molding, draft is the angle that you apply to the vertical walls of […]
