On March 23rd, the Governor of the State of Michigan, Gretchen Whitmer, announced a “Stay-at-Home” order. This order is currently scheduled to last until April 13, 2020. While this is certainly a challenging time for all, I can assure you BTI is doing our part to be productive in these unprecedented times. Toward that end, we are pleased to support our country and world under the Governments Critical Supplier Designation for specific projects. Additionally, while we understand that some interruptions are unavoidable, we wanted to provide an update on the steps we are taking in an effort to promote health and wellness while minimizing disruptions to our valued customers like you.
Other than limited staff on the manufacturing floor and service we are fully staffed, albeit remotely, in Mechanical, Electrical, Software and Controls Engineering. Additionally, we are partially staffed onsite in other key areas of our business including Operations, Finance, Shipping & Receiving and Purchasing. Lastly our Sales Engineers are available via email, text and phone to answers questions and provide support.
BTI’s Measurement & Testing Services division remains open providing balancing and testing services for designated “Critical Manufacturing Sector Suppliers”.
Our dedication to our customers, employees and country remains steadfast. We have seen this crisis bring out the absolute best in people and are encouraged, by working together, we will come out at the other end of this stronger, more nimble and certainly more adaptable!
Thank you for your time. We wish you and yours the very best!
Surface Finish Measurement Systems can be described as the measurement techniques for surface topography or texture.
There are three main characteristics of surfaces measured by Surface Finish Measurement Systems, these are;
It is important to measure surface texture because it controls surface friction, and as well as the transfer layer formation, especially during sliding. These forms of measurement systems are applicable in many fields of practices, these include;
The most popular processes where Surface Finish Measurement Systems are more common are;
In metal cutting, Surface Finish Measurement Systems are applicable in procedures such as sawing, planning, shaping, drilling, milling, turning, boring, reaming, and broaching. In Abrasive processes, the measurement systems are useful in grinding, barrel finishing, honing, electro-polishing, electrolytic grinding,as;forging, hot rolling, extruding, cold rolling, drawing and roller burnishing. Other processes where Surface Finish Measurement Systems can be applied, include; chemical milling, flame cutting, electron beam cutting, laser cutting and EBM.
The Surface Finish Measurement Systems has five main components, these are;
The work piece section is simply where the material to be analyzed or measured is placed, this section usually position the object which surface area is being measured, close to the DSLR camera that serves as the main measurement instrument. The DLSR camera measures the surface roughness, waviness, and Lay of the light source below focuses more light, to ensure that the camera captures the right, readable measurement. The camera support simply holds the camera directly in place to ensure that it stays in the right position to capture measurements. The captured image is simply computer where the captured measurements can be read. It should be noted that the Surface Finish Measurement Systems will require a professional setup for proper reading.
Surface Finish Measurement Systems has a wide range of uses. In the manufacturing processes for instance, in the machining of a product to produce a special surface texture, Surface Finish Measurement Systems must be optimized, in order to ensure that the final texture is usable, if the final texture is not adaptable or usable, the systems will be implemented once again, to modify the initial texture until the final texture meets the final specifications. Surface Finish Measurement Systems are also useful in other fields or areas, including;
The three main characteristics of a surface measured through the Surface Finish Measurement Systems are; the lay, surface waviness and roughness. The Lay is simply the direction of the predominant pattern of the surface. The lay is normally determined by the production method deployed on the surface. The surface roughness measured, is simply the measurement of the finely spaced surface irregularities. It is also referred to as the measurement of the surface finish. Surface waviness can be described as the measure of the surface irregularities especially when the spacing is greater than that of the surface roughness. Surface waviness normally occurs when there are problems such as vibrations, warping or deflection during the machining process.
Surface Finish Measurement Systems can be performed in two main ways, these are;
Contact methods of Surface Finish Measurement Systems normally involve the dragging of the measurement stylus across the surface. Special instruments known as “Profilometers” are used in this process. Contact methods of measuring surface texture usually provide a much faster result, though it is just as accurate as the non-contact methods of measurements. The non-contact method usually involves the use of certain devices to measure the texture of a surface without the device touching the surface being measured. Some of the most notable non-contact methods of measuring surface texture are;
The use of Surface Finish Measurement Systems such as low coherence profilometers
Surface Finish Measurement Systems are effective because they provide readings
The high-speed scanning feature of Surface Finish Measurement Systems ensures that measurements are taken through scanning, at high speeds varying from 1,000 and 30,000 points/sec or even higher.
The real-time feedback features of these systems ensure that real time feedbacks are provided, during the manufacturing or coating procedures, through the availability of application data. The application data obtained during measurements are usually sent to a process control system or software.
With an excellent visual inspection, it is easier to change the surface parameters during manufacturing or other processes. Readings are usually made available in-depth profiles, 2D cross-sections and 3D surface maps. The 2D cross-section readings are available in B-scans or C-scans.
