5 Things CNC Operators Must Know About Sizing Adjustments

5 Things CNC Operators Must Know About Sizing Adjustments

Today, companies that use CNCs find it nearly impossible to hire qualified CNC operators in the numbers required. As a result, they are hiring people with limited or no shop experience and training them from scratch. One area that poses special challenges for new CNC...
How to Make a Surface Plate Into a Gage

How to Make a Surface Plate Into a Gage

Surface plates provide a large, flat reference surface that can be extremely useful for inspecting incoming, in-process or finished parts. The surface plate is often referred to as the foundation of measurement since it provides the reference for much of the layout...
Grind to Finish: A Postprocessing Solution for Additive Manufacturing

Grind to Finish: A Postprocessing Solution for Additive Manufacturing

The increased use of additive manufacturing (AM) in the aerospace and medical markets fosters a growing need to finish the surfaces of additive parts to meet final application requirements. Since the additive manufacturing process is capable of producing components...
Toolcraft’s Customer Driven Transition to a Turning Cell

Toolcraft’s Customer Driven Transition to a Turning Cell

Toolcraft made a leap from manual machining and basic CNC technology to a sophisticated turning cell and has not looked back. It’s been a customer driven transition. So much of the work that a metalworking shop does is application dependent. For shops, the...
Choose the Correct ID/OD Gage for the Task

Choose the Correct ID/OD Gage for the Task

Circles are a frequently produced form in the shop. Many different processes generate this form — including turning, milling, centerless grinding, boring, reaming and drilling — and there are a variety of gaging methods used to measure inside and outside diameters...
The Right Gage for Measuring Small Bores

The Right Gage for Measuring Small Bores

Over the years, this column has examined using air gaging and back pressure to measure small bores (under 1 mm/0.040 inch). Air gaging can be an acceptable way of measuring small bores, but it does not provide any form information; it only provides the flow area as...
Know the Performance Levels of Your Gages

Know the Performance Levels of Your Gages

Micrometers and calipers are essential tools in the manufacturing world. They are versatile and cost effective. For many applications, especially those at inspection stations where variety outweighs volume, they are the tool of choice. They also have kept up with...
Differential Gaging: 2 Big Benefits for In-Process Part Control

Differential Gaging: 2 Big Benefits for In-Process Part Control

Differential gaging usually refers to the process of using two sensing devices and combining the results into one measurement. The measured dimension is the change in the position of the two sensing components. I’ve noted previously that differential gaging has some...
Precision Measuring Tools and Gages: A Primer

Precision Measuring Tools and Gages: A Primer

There is a wide range of precision measuring tools and gages that should be considered as basic requirements in a metalworking operation for ensuring good quality control (QC) processes. Most gages are available in analog (mechanical readout) or electronic (digital...
