Precision CNC Machining: How Can You Make Your Parts More Precise?

When you hear precision CNC machining, what do you think about? Isn’t all CNC machining “precision?” In a sense, yes. CNC machining allows you to make a lot of very precise parts relatively quickly. However, it goes much further than that. In this article, we’ll discuss what precision CNC machining is, how you to verify […]

Tolerance Stack Ups 501: Going Beyond Mechanical Fit and Into Predictive Design

Tolerance Stack-Ups are a vital component of any engineer’s workflow, to ensure successful mechanical design fit. But successful engineers in demanding industries such as medical, aerospace, and automotive, need to rely on data to do more than this. They need data to improve real design outcomes beyond “guess and check” — to improve design understanding […]

Injection Molding Design: Side Actions to Produce “Impossible” Undercuts

Design for injection molding has clear rules: Add draft. No undercuts. Round edges. Clear parting lines. Uniform walls, not too thick. But learning about advanced plastic manufacturing is like visiting Morpheus’s dojo in The Matrix: Some rules can be bent. Others can be broken. But breaking these rules is costly. Sharp edges require additional machining […]

Best Practices for Wall Thickness in Injection Molding

Heat and pressure most famously make diamonds. But they do more than that: Nearly every plastic product in your house was made with the same two forces. From the 1950s until now, injection molding has dominated consumer manufacturing, giving us everything from action figures to denture containers. Despite its incredible versatility, injection molding does have […]

How To Make a Great Engineering Drawing Manufacturers Will Understand

Before the days of CNC, machinists made parts purely based on 2D drawings. We’ve come a long way since then, and now the drawing is much less important to the process of actually cutting material, thanks to precise 3D modeling and CAM programs. That said, drawings are still a great way to call out special […]

Recommended Wall Thickness for 3D Printing

One of the most important considerations when designing parts for 3D printing is the wall thickness. While 3D printing makes prototyping easier than ever—not only in terms of cost and speed, but also in regards to DFM (design for manufacturing), you can’t disregard DFM completely. A design might be (barely) producible by 3D printing, but […]

DFM for CNC Master Class: How Design Requirements Drive CNC Manufacturability

In this webinar, we explore how to optimize higher complexity designs for manufacturability, where effort cannot be completely minimized. We will also explore the sources of manufacturing effort and key techniques for reducing relative effort for parts that are faster, more economic, and less risky to produce.  You’ll walk away knowing: How effort scales for […]

DFM for CNC Master Class: How to Minimize Risk in Manufacturing Design

In this webinar, we introduce you to the concept of design for least effort CNC machining. This concept will take you beyond the fundamentals of DFM (design for manufacturability), which is about do’s and don’t, and help you uplevel your DFM skills to design parts that are cheaper, faster, and less risky to manufacture.  You’ll […]

Bridging the Gap Between Design and Manufacturing

There’s a saying in the mechanical engineering world that really captures the gap between design and manufacturing: Anybody can design it; few people can make it.  As a design engineer, your job is to create a part or an assembly that will work properly. The manufacturer’s job is to make the part, make the assembly, […]
