Designing large scale automation and robotic systems using Solid Edge
By David Chadwick – Precision Robotics and Automation Ltd (PARI) is a leading developer of automation and robotic systems globally. Their customers in the automotive sector include established giants like Ford, Chrysler, PSA, Daimler-Benz, Tata Motors, Mahindra, and new significant players like VinFast. PARI designs, manufactures and installs complete, automated systems including multi-station lines for machining and assembly of powertrain components and assemblies.
PARI has been a major user of Solid Edge for 15 years with 160 licenses deployed at their headquarters near Pune in India. Typical automation solutions deployed by PARI incorporate a wide variety of robots, actuators and sensors and other mechatronic items. These systems can comprise over 25,000 unique components.
Mangesh Kale, Managing Director of PARI describes their design process. “If a six-axis robot is required for a specific application then we use robots from major suppliers like FANUC, ABB and Kuka, or other makes specified by the customer. We typically receive 3D models from these manufacturers and we integrate these into our automation system designs. However, many applications demand gantry type robots that we design and manufacture ourselves. In a typical solution, about 60% of the design is using standardized commodities of PARI. However, custom parts are typically 40% of the design. For example, the gripper sub-assembly for any material handling solution is typically a custom design. This design meets specific application needs to handle components at different stages in the machining or assembly process. The customization required for assembly processes is even higher. We find that Solid Edge is a very powerful and flexible solution for designing these sub-systems.” more>

By Michael D. Allen – My first job after leaving school was that of an associate engineer. This meant that I was half technician and half engineer, and I would design something and then build and test it. Because of this position, I frequently got some odd and interesting jobs.
One day a cardboard box showed up on my bench with a test box, a bunch of blueprints, a test procedure, and an “angle of attack” aircraft instrument. Management told me to grab an inspector, perform a functional test on the instrument, and buy off on all of the steps. This was the first aircraft instrument that anyone had seen in our lab area.
There were no program identifiers on the blueprints, the test box, or the instrument itself. I had no way to compare the numbers on the blueprints to any program. If anyone knew what the associated program was, he wasn’t telling.
The instrument was connected to the test box and turned on. A given DC input was supposed to drive the needle to a certain location on the dial face. This worked to a certain extent; the needle would drive to the commanded location but overshoot, back up, and overshoot again. The needle would be a blur, oscillating around the commanded location.
The test box was checked and appeared to be working correctly. Because the instrument was not working correctly, I ask the inspector if it would be OK to open it up to see what was inside, and he agreed. The instrument had a can extending several inches beyond the back of the dial face. The can had a sealed connector and a purge port to refill it with nitrogen. The inside of the instrument looked like several pocket watches stacked together. more>

Solid Edge 2021 Feature Highlights: Free CAD Models for Solid Edge Users
By Shannon Kruse -Solid Edge 2021 has been launched and with it comes a vast array of new capabilities and features for users! In this blog series, we will be highlighting a new capability every other week, allowing you to become familiar with the software and learn what Solid Edge 2021 has to offer.
This week’s blog post will be covering 3Dfindit.com, powered by CADENAS. 3Dfindit.com, an online visual search engine, streamlines the process of finding 3D models using advanced search functions such as classifications, geometry, filters, sketches and much more to allow you to significantly reduce technical search times and increase design efficiency.
3Dfindit.com for Solid Edge gives engineers like you a wide variety of intuitive search methods, making it easy to find the exact part you are looking for. You can create a rough model in Solid Edge and initiate a geometric search in 3Dfindit.com to find parts that are similar to that specific model. With millions of 2D and 3D CAD files verified by component manufacturers to choose from, you can easily select and configure the components that match your needs. Once the proper part is located, a single click places it directly into your active Solid Edge assembly.
CAD files of requested parts are automatically generated on the fly, ready to use in Solid Edge. Depending on the catalog, the digital parts are enriched with extensive metadata such as kinematics information to test motion sequences, centers of mass, material, environmental protection standards, order numbers, etc. This saves time by enabling engineers to find and deploy approved parts instead of manually creating them. more>
