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 manufacture and install 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.

Integrating Robots Into Automated Manufacturing Lines

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.”

Siemens Applications for Beam Analysis and Process Simulation

Another area where Solid Edge helps is in stress analysis of critical components. “Some of our gantry robots operate on a beam up to 8m in length. We use the beam analysis capabilities of Solid Edge Simulation to ensure that we optimize the beam section and support system for a specific application. We can ensure that the maximum beam deflection will meet our design criteria. This, in turn, ensures the accuracy and reliability of the system for our customers.”

PARI is also using Siemens Process Simulate software to optimize the cycle times of the systems they design. Process Simulate is also used to program the PLCs and robots that are integral parts of their systems. “Right now, we are working closely with Siemens to optimize the integration between Solid Edge and Process Simulate,” says Mangesh.
