One quick way to measure to this level of precision is with an Angle Meister – a digital protractor designed for bent tubing and sheetmetal see below. Also, in order to produce detailed Static Process Control (SPC) data, a more precise device is needed to extract the exact bend angle information. For example, to determine the exact springback of a tube, the means to measure to ☐.1° is needed. There are several factors that continue to drive the need for more exact bend angle measurement data. The Angle Meister – Accurate Digital Protractor for TubingĪs the detail of bend angle data collected increases, so to does the demand for a more precise bend angle measuring device. Another nice aspect of this approach is the relativity low initial investment with respect to the number bent angles you can qualify in a matter of seconds. This is a fast and easy way for “in process” inspection to take place.

If it drops in the fixture, the overall profile along with the bend angles are considered good see below. However, unlike sheetmetal, a typical round bent tube can be a little more difficult to hold tangent to a protractor together while at the same time trying to hold the pair up to the light to make an accurate angular read.įor low and high volume jobs, a simple check fixture usually does the trick. They are good for measuring a bent piece of sheetmetal day in and day out. You will also find a vernier type protractor around a brake. Low tech and most often accurate to about ± 0.5°, these devices don’t require a whole lot of calibration. By far the vernier style has been around for many decades and continues to be used to measure bent tubular angles world wide see below. Traditional protractors come in a digital or vernier style. However, a review of some of the various measuring techniques may shed a new light on an important subject. Bend angle quality often translates into a tolerance surrounding a target angle. Regardless of the bending process used to bend a tube, the vast majority of tube fabricators are interested in the quality of the bend angle produced.
