After all that has been written about Statistical Process Control (SPC) over the years, I am continually surprised at how often shop owners tell me they would like to do Data Collection for SPC, but they’re “just too small,” or they “can’t afford all that fancy equipment.” There seems to be a mistaken perception out…

Digital Video Comparator Digital video comparators utilize CAD drawings for accurate comparisons, incorporating laser measurement tools and specialized comparison software. The vision system is linked to a computer, which is used to calibrate and adjust the video comparator’s settings for precise measurements. Light Source The workpiece is positioned on a glass plate with a light…

When we think about making a simple measurement, such as an outside diameter, many methods can be used. These would include calipers, micrometers, mechanical snap gages, air snaps, CMMs, and special fixture gages, just to mention a few. The problem with all these methods is that while each is good in its own right, there…

The use of electronic temperature compensation in gaging has become a valuable tool in improving the accuracy and GR&Rs of gages in harsh manufacturing environments. The need for temperature compensation comes into play when the expected errors from temperature variation caused by the environment can use up more than 10% of the part tolerance. Where…

Optical comparators are measurement systems that offer extremely accurate and repeatable measurement data. They use video images, geometric dimensioning and tolerance (GD&T),light, lenses, mirrors, and cameras to examine the tolerances of parts, assemblies, and components. Optical comparators are a valuable tool used by quality control inspection teams to determine the effectiveness of production methods and…

How to Compare Products Downhole Laboratory testing such as the ASTM G65 wear test can give a good indication of an alloy’s performance. However, it will never accurately recreate the punishment that a hardband experiences downhole. Not only abrasive wear, but impact wear plays a big part, not to mention extreme temperatures, the effect of…

FREQUENTLY ASKED QUESTIONS 1. What standards cover the process of Cold Root Rolling? A. Both NS-1 and DS-1 have standards in place that cover the process of Cold Root Rolling to one extent or the other. Many of the major Rotary Shouldered Connection OEMs also have internal standards that cover some aspect of this process.…

Please contact your local Postle Representative or Technical Center for any information on proper weld parameters. Managing the heat of the welding process is absolutely critical during the hardbanding procedure. Proper pre-heating and slow cooling will assist the weld metal and the base material (tool joint, tubing upset, or other downhole tool) through their metallurgical…

What is a MOPA Fiber Laser Engraving Machine and How Does it Work? A MOPA fiber laser is a sophisticated laser system that utilizes a master oscillator and a power amplifier to generate high-power laser output with exceptional precision in controlling pulse parameters. This design is extensively employed in a diverse range of industrial and…
