The Challenge


Angus Robson of Robson Holdings (2004) Limited, is a highly specialised manufacturer, who supplies rock-breaking machinery to a global market. Angus had been experiencing issues with a part in one of his machines that was working for thousands of hours on some jobs and breaking at as little as twenty-five hours on others.

Angus had approached various engineering specialists to help him understand the problem, but found they often pointed him in the wrong direction, “I had kind of identified what the problem was, which was the way that the load was coming on. My previous experience with the machine told me one thing and all the experts told me to stick with that one thing. In actuality, it was something completely different.”

Angus’ challenge was amplified by the fact that he had particular design parameters he had to work within; “I had to try and find a solution that stayed within the original design framework, so we were pretty constrained about all of our options.”

Project Goals


The primary goals of Angus’ project were to identify why the part was performing inconsistently in different environments, and to achieve consistency in the amount of time the part could run before breaking. It was also important for Angus to be part of the design and modelling process, so he could achieve confidence in the future operation of the part and validate it properly, “I didn’t feel confident that I was close enough to the research and development process to validate it with a consultancy.”

Angus has been conducting research and development in the engineering space for the past thirty-five years and could usually “hunt problems down and solve them quickly.” Angus was hopeful the problem could be resolved because he knew that some parts were operating for over one thousand hours and not failing. But he continued to struggle to understand what was causing the inconsistency in the part.

“It was mainly down to Matthew (CADPRO), once Matthew had given his take on it then we could make the software work. I was amazed at how hard it was to get info from, honestly world experts. Then I started talking to Matthew and he knew what I was looking for and how to set it up.”

“I’m putting this stuff out internationally, the supply chain is immense, the distribution chain is immense and if it goes wrong it’s a massive problem, so you absolutely have to be confident. I got confidence from this exercise.”

The Solution


After consulting with experts internationally and coming to no sound conclusion, Angus contacted CADPRO Systems. CADPRO evaluated Angus’ problem with the part and offered a path to a solution using a module in Autodesk Fusion 360. CADPRO worked with Angus to perform simulations in Fusion 360, comparing the models to real-world data that Angus had accumulated. From these simulations and models, the problem with the breaking part was identified, and fixed accordingly.

Ultimately, the solution to Angus’ breaking part was achieved with CADPRO’s technical engineering expertise and the capability of Fusion 360 to perform the necessary modeling and simulations. Angus explains, “It was mainly down to Matthew Weake (CADPRO), once Matthew had given his take on it then we could make the software work. I was amazed at how hard it was to get info from, honestly world experts. Then I started talking to Matthew and he knew what I was looking for and how to set it up.”

Business Outcomes


For Angus, getting the part operating properly and having confidence it would continue to operate without breaking was critical. His current machines operate in numerous global locations, as he remarks, “not places where you want problems”.

The modelling and simulation process gave Angus confidence the correct path was being followed and significantly reduced risks to his business. “I’m putting this stuff out internationally, the supply chain is immense, the distribution chain is immense and if it goes wrong it’s a massive problem, so you absolutely have to be confident. I got confidence from this exercise.”

The simulations in Fusion 360 that CADPRO assisted Angus to develop provided a point of reference, not only to fix the broken component, but also to help him identify problems in future, “this has allowed me to know what’s going on a lot better, so then I can much more confidently be sure about how machines and parts will operate in varying climates.”

The Result


Angus’ engagement with CADPRO allowed him to distribute his machinery internationally with greater assurance. The simulations in Fusion 360 provided him with clarity about the inconsistency of the parts’ operation and its future operational requirements. While the ability to work alongside CADPRO for the research and development phase of the project meant that Angus could properly validate the solution.

CADPRO’s solution also saved Angus the cost, time and stress of going through a consulting agency; “The thing with my dealings CADPRO, was that they got it straight away, had the gear, and didn’t take 30 hours to set up for one run and then give you a dud result because it was you that was wrong or the modelling. Because half the time that’s what happens. You see a result and think that doesn’t seem right, but not know enough about how it was done to tell. With the CADPRO solution I could do peripheral solutions and check.”
