The measurement of length of rolled parts
Rolled parts are often used in many applications, and their length is of critical importance. If a rolled part is too long, it could potentially cause difficulties during production, and may not give the end-user the desired result. To ensure that rolled parts have the correct length, various measuring techniques have been developed.
One of the most common methods of measuring the length of rolled parts is lapping. This is the process of running a pair of flat steel plates together with a predetermined spacing between them. As the parts are run through the machine, the plates will come into contact with the thickness of the parts. The length of the parts can then be calculated by measuring the distance between the two plates. This process is used to ensure that the parts are of uniform thickness over the entire length.
Another popular method for measuring the length of rolled parts is strain gauging. This technique uses strain sensitive gauges that measure the part’s thickness. From these measurements the thickness can be accurately determined. This method is often used when parts require very precise tolerances, or when the length must be determined quickly.
A third method used to measure the length of rolled parts is optical measurement. This technique uses a laser beam to measure the dimensions of the part. Optical measurement is usually used when more precise measurements are required than can be attained with other methods.
All of these measuring techniques have their strengths and weaknesses depending on the application. Some techniques, such as lapping, are useful for general-purpose parts, but may not be suitable for more complex shapes and configurations. Strain gauging, on the other hand, is effective for parts where precision and accuracy are of the utmost importance. And optical measurement is the best choice when extremely accurate measurements are needed.
No matter which method of measurement is chosen, it is important to ensure that the rolled parts are of the correct length. By properly measuring the length of rolled parts, the quality of the parts and the successful implementation of any production process can be ensured.
