06.Nov.2012 A Bit About Bits: Why Size Matters

One important consideration when choosing the right bit for a job is bit size.  Size matters with router bits because many important properties are directly related to the size of the router bit.  Larger bits are more ridged and they can cut faster, but they also require more power, have larger kerfs and have larger [...]

22.Jul.2012 A Bit About Bits: Introduction

A Bit About Bits: Introduction Let’s talk a bit about bits.  I enjoyed writing “5 Things Students Should Know About CNC” and with a new semester quickly approaching, I felt a follow up article about bits was in order.  Bits are a deep topic, but over the next several articles we will cover the basics [...]

19.Jul.2012 5 Rules Every Design Student Should Know About CNC Prototyping

5 Rules Every Design Student Should Know About CNC Prototyping 1. CNC integrated manufacturing does not exist to eliminate the need for technical skills. It can produce designs with greater accuracy and repeatability than we are capable of, but it is still just a tool that enables accurate production.  Just because a CNC router comes [...]

26.Jun.2012 Applying Threads and Fastners:

Behind all the data in callouts on plans and bills of materials are the real features that hold our designs together.   While final selection is often an engineering decision, understanding fasteners makes creating practical designs and prototypes possible.  It also helps us to understand why existing products are designed and produced the way they are [...]

02.May.2012 Threads and Fasteners: Part 2

It is useful to be able to read and produce proper engineering style thread notations. This formal style of referring to threads is commonly used in component data sheets, for communicating with manufacturers and in a shortened form when shopping for fasteners. The basic components of a thread call out are the major diameter of [...]

27.Apr.2012 Threaded Fasteners : Part 1

How we hold things together matters.  While final fastener choice is usually an engineering and manufacturing decision, a few basic rules about fasteners and understanding how they work helps us to create plausible designs and communicate effectively with other disciplines.  Being able to create logical designs on our own is also essential when working on [...]
