It doesn’t matter how beautiful your theory is, it doesn’t matter how smart you are. If it doesn’t agree with experiment, it’s wrong. – Richard P. Feynman We are often requested to convert a casting to a hog-out and I wrote about things to consider in that conversion here. Today, I pose to you: Are […]
Failing More Often: Gaining from Randomness and Volatility
ISO Quality Management System Series: Part 3 Welcome to the third and final installment in our quality management series. I first noted that, although our ISO / AS quality management system has contributed to a reduction in errors made in precision CNC machining aerospace parts, improvement results have leveled off. Secondly I showed that, despite […]
Improving Precision CNC Aerospace Machining
ISO Quality Management System Series: Part 1 Evaero’s quality management system (QMS) is registered to ISO (9001:2008) and AS (AS9100C) standards for the precision CNC machining and assembly of aerospace parts. Over the years, I have been asked repeatedly if a QMS is beneficial to our company and in turn, to our customers. The short […]
The Art of Precision CNC Machining
Today I want to talk to you about latkes and the practice of becoming a good machinist. I had promised today’s post was to have been about precision CNC machining and errors but, in favor of a couple of other more timely topics, I’ve decided to postpone it until later this month. During the holidays, […]
Machining Parts: Castings vs. Hog-outs
Much of the manufacturing work Evaero does requires the CNC precision machining of castings made by foundries that pour/inject liquid metal into a mold where it can cool from a liquid (or semi-solid) state to a solid state via a process called “solidification.” Because the molds closely approximate the geometry of the final part, after […]
CNC Precision Machining: Behind The Scenes
The bulk of the manufacturing work that Evaero does involves CNC precision machining of complex metal parts. The aerospace and defense industry has increasingly become commoditized, and I find our buyers and decision-makers, while they know what they need, don’t totally understand what we do. For that reason, I thought it might be worthwhile to […]
