It’s one of the first tools that come to mind when you ask a machinist to name a measuring tool and the caliper is normally the most important tool in their toolbox. A recent Top 5 Digital Calipers for Machinists article put together and published by Practical Machinist have given the crown to the worthy winner which is the Mitutoyo 500-196-30 Absolute AOS Digimatic Caliper.
The Japanese-made Mitutoyo AOS Digitmatic Caliper is the best in class when it comes to precision metrology hand tools. It’s equipped with standard outside and inside jaws, made from hardened stainless steel construction and has ABSOLUTE System scale for error-free, high-speed measurements. The ZERO/ABS button allows the display to be Zero-Set at any slider position along the scale for comparison measurements. This button also allows return to the absolute (ABS) mode for displaying the true position.

The precision centre finder is used to accurately position the tool axis, centrally to the workpiece. It’s an easy to use gauge able to find the centre of a bore, external cylindrical boss or align with centre punch marks and is supplied with 6 feelers for internal and external alignment. The 10mm diameter mounting shaft has a metric gauge fitted to the main body and this metrology tool is also known as a Dial Coaxial Centring Indicator.

History was made on July 20th 1969 as the first man walked on the moon, all thanks to the Apollo Program which changed the world we live in now in terms of technologies and engineering. The program was a huge accomplishment for engineering and due to its success, it resulted in a massive overhaul of new technologies and products coming into the world. Off the back of the Apollo Program, they stimulated multiple areas of technology (over 1,800 products, in fact), these include; the CAT scanner, computer microchip, cordless power tools, joysticks, and satellite television.
Here are some stats from the Saturn V rocket which went into space:
• The Saturn V rockets that launched Apollo 11 into space was 363 feet tall, weighed 6.2 million pounds and took 7.5 million pounds of thrust to get the Armstrong and his team off of Earth.
• 400,000 people are estimated to have worked on the program.
• It was a collaborative effort between Boeing, North American Aviation and Douglas Aircraft.
• It was an incredibly complex machine made from over 3 million parts.
However, what was the status of industrial metrology tools in 1969 to support the colossal development and manufacturing tasks of the Apollo Program?
“Renishaw was only established in 1973 after the invention of the touch-trigger probe during the Concorde engine development program at Rolls Royce in the early ’70s. Until this time the first coordinate measuring machines that had emerged were extremely primitive manual devices with only a limited digital readout and mechanical ‘hard’ probes. The laser tracker, prominent throughout aerospace manufacturing today, was not invented until 1987. The articulated portable arm CMM patent was filed in 1974.” (source: metrology.news)
In conclusion, all of today’s incredible advanced metrology tools and technologies were not available to support the development and manufacturing involved for the Apollo Program and getting a man to the moon. However, we celebrate the amazing achievement of those involved back in 1969 and we can only imagine how tough it was in achieving the precision which helped them complete the mission as a success.
