CNC rotary tables play a vital role in the performance of multi-axis machining centres. As table accuracy and reliability are of paramount concern throughout the product’s lifetime, Matsumoto Machine Corporation (MMK) has taken a pragmatic two-pronged approach to reducing indexing errors and improving performance.
To achieve consistent sub-micron measurement accuracy, an automated line scale calibration system developed by the Standards and Calibration Laboratory (SCL) in Hong Kong made automatic error compensation a key design criteria.
Gabriel Hughes was once asked to calibrate a 2x4 at a previous job. While this may sound strange, the customer sent it in to have the precise dimensions calibrated. The wood was used to keep a door closed at a certain height, which they needed to monitor because of airflow.
Dr. Bonnie Dunbar, a five-time space shuttle astronaut who spent more than 50 days in space, described her experiences in flight – highlights included the 90-minute trip to circle the Earth and experiencing weightlessness – for a special Women in Metrology event at CMSC 2019.
Flexible Concepts Inc. is a large automotive supplier based in Elkhart, Indiana, USA. It set itself the challenge of being able to offer customers guaranteed machining capability, as part of a strategic decision to use innovative engineering to progressively increase the size of its business.
Confocal sensors are increasingly used for fast distance and thickness measurements. Different sensor and controller models open versatile fields of application, e.g. in the semiconductor industry, glass industry, medical engineering and plastics production.
When the parts are rejected or the gages or instruments are giving dodgy answers the red flag goes up and panic usually ensues. Everyone involved defends their turf, talent or toys which is normal but rarely answers the question of what’s gone wrong.
Gage manufacturers and calibration laboratories often find themselves in this minefield. New gages or instruments are supplied or calibrated and immediately returned by the customer because they aren’t correct.
The latest-generation Marposs Optoquick™ flexible, precision shop-floor shaft measuring system utilizes non-contact optical scanning to provide rapid and accurate measurements while the part is rotating.
