Last month’s newsletter was a discussion about tolerancing parts and assemblies and how they interrelate and drive cost. This month we are going to give a brief overview on cutting tools used in the CNC milling process. This list is by no means comprehensive as there are too many types and details to cover in…
Welcome to 2011 everyone! Let me start by announcing that we now have the ability for readers to leave comments at the bottom of a newsletter. So if you want to leave one, please scroll to the bottom. I hope this allows folks to have a dialog about the topic. Last month’s newsletter was a…
Last month’s newsletter was a case study of a part who’s cost was greatly reduced with some DFM work. This month we are going to have a brief wrap up of 2010 and wish you all a Happy Holiday. We started January with a case study of a part with great DFM potential that wasn’t…
Last month’s newsletter discussed title block tolerances. This month we are going to look at another case study like the ones we did back at the end of 2009 and beginning of 2010. The expression “The proof is in the pudding” has never been more applicable than with this part here in figure A. We…
Last month’s newsletter discussed surface finish roughness. This month we are going to talk about title block tolerances and significant digits. This topic was suggested by Lou at Brookhaven National Labs. Thank you Lou! Nearly every drawing format in use today has a title block with a standard set of block tolerances. The purpose of…
Last month’s newsletter discussed a broad overview of DFMA in the supply chain and presented a white paper on the topic. This month we are going to talk about surface roughness on machined parts and how that affects cost. This is the second topic suggested by Larry V. at Lockheed Martin – thank you Larry!…
Last month’s newsletter discussed optimal corner radii. This month we have a guest writer who will cover a broad overview of DFMA (Design For Manufacturability & Assembly) from a strategic supply chain perspective. Jon Edwards works in the sales department here at Pro CNC. This is a summary for a white paper which can be…
Last month’s newsletter discussed some ideas for making drawings simple for machining. This month we are going to revisit the topic of inside corner radii and talk about a new detail not previously discussed. This topic was suggested by Larry V. at Lockheed Martin – thank you Larry! For many parts, the length of time…
Last month’s newsletter was an overview of turning centers. This month we are going to look at ways to simplify your drawings with the express purpose of reducing the cost of manufacturing and inspection. I am going to make an assumption for the sake of this newsletter that the machine shop making your parts is…
