Color mapping is commonly used as a profile analysis tool in first article inspection primarily because it allows you to quickly visualize the differences between the scanned part and its nominal CAD model specifications. After an object is scanned, point cloud software highlights the differences using a color map. Each color represents a different degree of variation between the scanned part and the original design so that manufacturers are better able to understand what the part’s actual condition is and refine and improve the corresponding manufacturing processes.
Bluing and scribing of castings (also known as casting layout) is a tried-and-true method for dimensional inspection of a metal part made typically by sand casting or permanent mold. By placing the dimensions from a drawing on to the actual part, you can determine whether it meets the specifications. Although this method has been used for decades, new technologies have effectively superseded the need for it in most cases.
3D scanning can be used for multiple reasons, including first article inspection, reverse engineering, and other types of measurement applications. The purpose of 3D scanning is to collect data points to create a digital representation of the object. These data points can be gathered using lasers, white light, contact sensors, and other methods depending on the characteristics of the object being measured.
When you work with subcontractors to fabricate parts or components, you must be sure that their quality standards are consistent both with your standards and with any regulatory requirements for the finished product. Ensuring supplier quality assurance is an essential step in your own QA process, but how can you confirm that all your subcontractors meet your specifications?
Whether you decide to outsource reverse engineering services or purchase equipment so you can do it in-house, you must work with a qualified provider that you trust. The reasons may be obvious in the case of outsourcing, but selecting a good reseller when you decide to buy is just as important.
If you have decided that purchasing your own reverse engineering equipment is the most cost-effective solution for your project, the next step is determining what to buy. Countless types of equipment are available, with a range of features and from several manufacturers.
If you have decided that outsourcing reverse engineering services makes the most sense for your project or business, you still have some decisions to make. Not all reverse engineering applications are the same. You must decide what type of equipment to use and what kind of output you need, as well as consider a range of other factors.
If you need reverse engineering for your business, you may come to a point when you must decide if you want to outsource to a qualified provider or purchase equipment to do the job in-house.
The Ontario government recently passed the decision to withdraw a proclamation for the repeal to the Industrial Exception that was scheduled to be enacted September 1, 2013.
In order to obtain an engineering degree, you must learn certain concepts and skills in school. However, developing an engineering career means your education continues on the job. One field not typically taught extensively in engineering school is metrology, but for any engineer entering the field of manufacturing, understanding metrology is essential.
