Control technology is an overall term for the equipment array used for Quality Assurance teams as they guarantee the quality of products produced by the Dagesh Group. Using advanced robotics, D3 cameras and scanner technology, we can assure quality at the highest level and with great speed.

Some quintessential terms:

First, it’s important to organize the terms and differentiate between Quality Assurance and Quality Control:

Quality Assurance – QA: Relates to the range of actions needed throughout development, production, distribution and ongoing product maintenance processes in order to guarantee quality and standardization. Quality Assurance is an inseparable part of the product management process, and is used as an efficient tool for tracing and comparing set quality demands with what’s actually done in terms of the conditions involved in the process.

Quality Control – QC: Relates to the testing, overseeing and authorization process of product quality, as defined by the client. Quality Control processes are meant to check the final product or the manufacturing process at a certain point, in order to make sure that pre-defined quality demands are applied in the best way possible, and meet the obligated standards. 

Control Stages

As part of Quality Control, each product produced by the Dagesh Group goes through one or more of the following stations:

1. Manual control – checking apparatuses such as altimeters, pins and additional accessories.
2. Precise, industrial measuring machines: CMM – Coordinate-Measuring Machine.
3. Advanced equipment for part imaging:
   1. First camera: SHTINBECHLER (ZAISE) 8MP.
   2. Second camera: 5MP with advanced, faster-than-usual imaging technology to provide results at the highest level.
   3. CREFORM laser scanner for larger parts, scanning parts at a volume of 16 cubic meters.
   4. A robotic chamber.

Some of our products are machine and/or camera-tested, and require the support of line software throughout all control stages, whether by machine or camera.

Operating Control and Measuring Technology

A measuring machine operator, whether an applied engineer or simply a technically-oriented individual, must be familiar with the control standards. Early learning of the device’s points and templates allows the operator to “drag” various modules, put them together in the software tools in their exact position, and build a quick layout.

According to Sashkis: “If the parts are uniform, you can save the work layout in the kiosk so that any employee can attach the parts to the device in the way shown by the software, and get an image of all the parts within 10 minutes. Nowadays, a machine operator can operate 2 cameras simultaneously to take between 14 and 16 parts for 8 hours. Our vision aspires to have the chamber independently able to carry out a larger number of images.” He further explains: “Even though the layout-making built-in software is very advanced, we’re not using that function at this point. The reason for that is the versatility of work at the Dagesh Group; every part has to go through a comprehensive yet quick control process, which is why the same software written on the line is currently being used for all measuring machines. However, in the next stage we aspire to create software for parts that are bulk-tested and recur several times a year, in order to get an immediate result after imaging, thus streamlining Quality Control.

Quality Control Advantages

There are distinct advantages to using advanced technologies such as the robotic chamber and quality control in the production process:

1. Imaging duration and quality – current control cameras are less advanced than the new chamber, the imaging duration of each part can take an hour or even longer, with each capturing at least 3 sets of 10-12 images. “If the part has a bore or small screws, there’s a need to take additional images in order to gather enough material from the bore’s diameter,” Sashkis says. “To understand the scale, Dagesh programs 20-30 parts per week.” The new technology and advanced equipment Dagesh possesses allow for faster and higher quality imaging at a resolution of 15MP, combined with imaging software that operates using AI technology. The imaging software is automatically operated, reducing the dependency on personnel and allowing us to receive complete and detailed imaging with fewer images. “Therefore,” as Sashkis explains, “it takes about 15 minutes from the moment a small part enters testing to when we receive final imaging – including control and report results. Another advantage is that imaging new and similar parts will be done by duplication, and will only take 3-4 minutes.”
2. Imaging several parts together – another advantage of the system lies in its ability to simultaneously contain 4 or more parts in the device so they can be imaged together, then separated via software tools, and separate report can be produced for each part. Robots are usually used as tools for the mass production of parts as a series that repeats itself, but this isn’t how we do things at Dagesh. “We regularly have 100 or more different parts, in a 10-to-300-part series,” Sashkis tells. “The advanced system allows immediate imaging within 10-12 minutes and gets imaging of all the parts in an additional 10 minutes, which makes the work times and methods significantly more efficient.”
