Calipers are highly versatile tools designed for a wide array of distance measurements. These tools allow you to measure inside diameters and outside diameters with exceptional ease. Although micrometers provide more accuracy, they have limitations in terms of measurement range. With that, an average caliper can span from two inches to four feet.

Today, there are three basic types of calipers, including vernier, dial, and digital. Vernier variants are the original design, dial variants are second-generation calipers, digital calipers are the latest forms of calipers and have been used in shopfloor environment for more than two decades.

Unlike dial calipers, digital calipers do not feature gear systems, pinions, or racks. These differences make them more shock-proof. In addition, digital calipers can easily convert from inches to mm and vice versa. If you are looking for a digital wireless caliper, you should consider Mahr Federal 16 EWRi Digital Wireless Calipers. Let’s find out more about this amazing product in this product spotlight!

Understanding Precision Measurement

Here, we will take a look at the concept of measurements at a high precision level. If you have a career in metrology, precision measurement is already an everyday part of your life. By nature, the world of measurements is complex. That said, the following will be a rather simplistic view of the principles of measurement, how it works, important factors in measuring, and how tools should be correctly used for measuring.

For a most fundamental measurement understanding, there are three all-important terms that are frequently used incorrectly, confused as having the same meaning, and that get mixed up – but which should be aptly understood – resolution, precision, and accuracy.

How To Unload The Coordinate Measuring Machine

A coordinate measuring machine, frequently referred to as a CMM, is an integral player in the world of parts inspection and quality control procedures. In order for a product to meet with customer approval, it must first meet the requirements set forth by parts inspection and quality control. In metrology, a CMM is one of the most common pieces of equipment used during inspections. It is, in fact, very much in demand be at the metrology lab or the production floor.

Because the lab and the production floor are not located in the same place, it becomes necessary to transport and transfer the coordinate measuring machine. This is where you can run into problems. Many of the parts are large and the process of moving a CMM from one place to the other is arduous and long. What happens all too often is that bottleneck issues arise during transport, and that means a work slowdown. How can this be avoided?

What Can Variable Gaging Do For You?

Micrometers, calipers, and scales are some of the measuring instruments that are used in a wide range of manufacturing processes because they are cost-effective and easy to use. If you are just looking to get a quick indication of a part’s size, they will suffice. However, these tools require a skilled operator and proper alignments must be made to produce reliable results. That’s why their measurement speed, performance, and accuracy are sometimes limited.

If you are looking for alternatives that can help you qualify parts in an easier, faster, and more accurate method, you should look at variable gaging. These gages can help you compare a part to an external standard and more without much operator involvement and influence. Let’s find out more on what variable gaging can do for you!

Bore gaging is basically a convenient term for the transfer or measuring tools that are utilized in the process of measuring holes in an accurate manner. There is a rising concern for TQA or Total Quality Assurance, and that’s why bore gaging has become increasingly important in metrology and other manufacturing processes. For instance, they are used to measure difficult-to-assess internal features such as deep bores, threads, and splines.

Next, you should know that with the continued expansion of machine capability, the need for dimensional gaging to be able to cope with the increased complexity of component parts and tighter limits on tolerances also increases as well. Even if you are not so much concerned with making a part to a specific tolerance band, you should always remember to use a gage that discriminates size variation. In this post, you will find out more about an excellent bore gaging tool that can make this task easier. Introducing the Fowler Bowers XTH Pistol Grip Only.

There can be no denying that especially in the last quarter century, metrology has advanced by leaps and bounds. Optical technology, 3-D scanners, and the advent of lasers have all served to evolve metrology to where it is today. So it only makes sense to assume that new developments, improved inspection, advanced quality control, and more will continue to evolve and make the manufacturing process one that is ever-changing. What will the next ten years bring?

How To Use A Dial Caliper

For automotive and machining applications, a tool called a dial caliper is frequently used as a reliable precision tool that is relatively easy to operate. It is capable of measuring parts to the thousandth. And though it is, as just stated, more or less easy to use, it is important that a dial caliper be used correctly and read accurately.

Keeping in mind that it is far easier to show someone how to use a dial caliper than it is to simply write it on a piece of paper and read it, not to mention far more beneficial for both parties, here is a guide on how to use a dial caliper.

Everyone knows that it is important to check the quality of shiny coatings, measure surfaces that are about to be coated, and more. What’s more, it allows coating chemical manufacturers, electroplating firms, plastic parts producers, etc., to safely document and assess surfaces. The question now is how you are going to do that. What methods should you use for testing and quality control for plastic coatings? Let’s find out more!

Best Practices for Rockwell Hardness Testing

Posted on by George Chitos

Hardness, as applied to most materials, and in particular metals, is a valuable, revealing, and commonly employed mechanical test that has been in use in various forms for more than 250 years. As a material property, its value and
importance cannot be understated; the information from a hardness test can be used to provide critical material performance information and insight to the durability, strength, flexibility, and capabilities of a variety of component types from raw materials to prepared specimens, and finished goods. Hardness testing is widely used in a multitude of industries and plays particular significance in structural, aerospace, automotive, quality control, failure analysis, and many other forms of manufacturing.

The difference between system A and System B is as follows.  System A  is plus or minus a turn from notch location vs System B which uses the back face of the gage to check for maximum material.

These gages also come in truncated or full form.  The difference being is the truncated crest will allow you to check the pitch diameter but not the radius.  The full form allows you to check the radius of the thread.
