Trends in CAM technology by Dr. Yavuz Murtezaoglu

Dr. Yavuz Murtezaoglu

There are more than 1 million CAM Operators worldwide and they are using around 40 different major CAM software brands. The focus of the CAM vendors in 2023 is going to be delivering more value to their user base by providing annual maintenance updates.

Most CAM vendors are focusing on improving the User Experience to improve the productivity of the CAM operators and to reduce training needs for new operators. This means “easy to use” and “easy to learn” are both equally important topics to address by CAM vendors. Capabilities of tool path technology in CAM systems will evolve to address the needs for higher productivity of the CAM operators. A good example of this trend is quick adoption of tool path strategies like “One click Deburring” or “Fully automated Rotary machining” in many CAM systems. Many CAM Software vendors are deciding to license such tool path technologies from ModuleWorks as their main component provider for tool path calculation and simulation. This frees up their development resources to address the complete workflow from design with PMI (product manufacturing information) to post processing.

CloudNC: Cloud-Based CAM Automation Yields Faster Results and Higher Quality

 
January 10th, 2023 by Jeff Rowe

Cloud-based computer applications are all around us and continue to expand and influence many aspects of our personal and professional lives. Digital, or computer-based machining (CAM) is no exception.

Although CAM and computer numerically controlled (CNC) technologies have been with us for several decades, cloud-based methods are relatively new, but evolving at a rapid pace.

The first NC machines were built in the 1940s and 1950s, based on existing tools that were modified with servomotors that moved tools or parts to follow points fed into the system on punched tape. These early servomechanisms were rapidly augmented with analog and digital computers, creating the modern CNC machine tools that revolutionized machining, and more recently, cloud-based processes.

Simulation Assets are Leveraged More Fully

Throughout the coming year simulation will continue to take on an even greater role as companies search for ways to become more innovative, leverage resources, and keep pace with accelerated product development cycles.  Consequently, the expanded use of advanced simulation tools beyond expert CAE analysts (i.e., the democratization of simulation) will become an even greater industry-wide priority.

Democratizing Simulation allows product engineering, manufacturing, and support organizations to leverage their CAE investments and resources more fully by allowing expert analysis to focus their time and expertise on high-priority simulations while allowing non-experts to perform basic (and even some advanced) CAE analysis.  The result of simulation-driven design will compress product development cycles and accelerate innovation with a measurable increase in product quality.

Bantam Tools: Small CNC Machines Yield Big Results

 
October 25th, 2022 by Jeff Rowe

MCADCafe recently interviewed Bre Pettis, CEO of Bantam Tools about several things regarding his past and current endeavors that interestingly involve additive and subtractive manufacturing.

Pettis has had many personal and professional iterations during his career, but has always stayed close to design and manufacturing. Pettis is probably still best known as the co-founder and former CEO of Makerbot Industries, a 3D printer/additive manufacturing (AM) company now owned by Stratasys. He left Makerbot in 2014. In June 2017, Pettis acquired start-up Other Machine Co. — now known as Bantam Tools — from its founder and CEO, Danielle Applestone.

Bantam Tools builds reliable and precise desktop CNC machines. Since 2013, the company has been manufacturing desktop CNC machines for engineers and product designers enabling them to bring machining in-house and accelerate their rapid prototyping processes. Its CNC machines are also widely used by educators in classrooms and makerspaces. The company is on an ambitious mission to build an ecosystem of hardware and software products that will empower its users to create sustainable energy sources, fight climate change, land on Mars, prevent the next pandemic, and close the growing skills gap in U.S. manufacturing.

Bantam Tools strives to keep as much of its manufacturing in-house as possible, and its machines are assembled and tested in-house in Peekskill, NY.

Sigmetrix: Mechanical Variation Management Helps Engineers Maker Better Decisions for Building Better Products

 
August 17th, 2022 by Jeff Rowe

We recently spoke with Ed Walsh, VP of Global Sales at Sigmetrix for an update on the company and its technologies. During the interview, he spoke how the company continues to be focused on helping customer design and build better products through mechanical variation management.

Sigmetrix is unique because it’s not just a software company, but also a service and training company that together provide a comprehensive solutions approach for its customers.

Sigmetrix is a company whose focus has always been on helping companies create better products through mechanical variation management.

Walsh said, “We can break mechanical variation management down into two parts. Better products would mean a product that’s safer, maybe more efficient, produces less pollution, and is more accurate. For us, that’s what better products mean. Variation is something that comes in and can make those products not so good. Maybe makes the product less competitive or makes customers less happy. So, we’re trying to manage that to make better products”.

“Our customers want to get the most out of their technology investments with the most efficient use of their resources. This includes things like having solutions that scale to multiple skill levels in an organization. We address this need by having our cornerstone tolerance analysis tool (CETOL 6 Sigma) that is used for advanced applications because it’s very powerful, but also a 1D tool (EZtol), that’s relatively simple to use. We are seeing an increased demand for tools that teach people geometric dimensioning and tolerancing (GD&T) as they use them by incorporating training solutions in all of our tools. We feel that that education helps establish a use case, or ability to be used, by that whole spectrum of users”.

MCADCafe Interviews Ed Walsh, VP Global Sales, Sigmetrix

What Does Mechanical Variation Management Mean?

Sigmetrix’s mission statement is “Better products through mechanical variation management.” We asked Walsh if he could elaborate on what that actually means.

I think the way we can best describe it is by defining what variation actually is. Variation can represent any number of things between the viscosity of a fluid or the amount of flow through a circuit, just based on the random variation of how things work in the world, for example, weather”.

SPEE3D: Making Additive Manufacturing Easier Is Only the Beginning

 
July 18th, 2022 by Jeff Rowe

It’s 2022 and additive manufacturing (AM) companies and technologies continue to proliferate, some more successful than others. While many new companies in this space claim to be unique and innovative, truth be told, relatively few actually are. That said, when we spot something that truly is innovative we take note, and feel that SPEE3D definitely qualifies.

We recently spoke with SPEE3D CEO and co-founder, Byron Kennedy, about his company and its unique AM technologies, materials, and processes.

SPEE3D is an Australian-based company and a manufacturer of metal-based 3D printers. The advantage of these 3D metal printers is that they’re very fast and also transportable. This means customers can put them in trucks or ships and take them right to the front line where parts can be manufactured and immediately used.

SPEE3D printers enable affordable metal additive manufacturing processes. They make metal parts quickly, leveraging metal cold spray technology to produce industrial quality metal parts in minutes, rather than days or weeks. The process is powered by kinetic energy, rather than relying on high-power lasers and expensive gasses. Finally, the process provides metal 3D printing at costs normally associated with traditional production methods.

How did SPEE3D get started? Kennedy said, “Our (he and the other co-founder and CTO, Steven Camilleri) background was in manufacturing. We previously had another company designing electric motors, sold that to a large US multinational and worked with them for near on 10 years in manufacturing. We saw 3D printing coming, but the reality is that it was just too expensive, and too slow. So when we finished up at the motor company, we wondered if we could take 3D printing into the production space and really solve this cost and speed issue. Thus, the company was born”.

Cadence: A Natural Progression From EDA to CFD

 
June 9th, 2022 by Jeff Rowe

We recently spoke with John Chawner, Senior Group Leader at Cadence about the company’s entry into computational fluid dynamics (CFD) technologies after many years of being known for its expertise in electronic design automation (EDA).

Cadence has long been a leader in electronic systems design, building upon more than 30 years of computational software expertise. The company applies its underlying Intelligent System Design strategy for creating innovative software, hardware, and IP solutions.

In turn, Cadence customers are some of  the world’s most innovative companies, delivering extraordinary electronic products from chips to boards to complete systems for the most dynamic market applications including hyperscale computing, 5G communications, automotive, mobile, aerospace, consumer, industrial, and healthcare.

Generally, computational fluid dynamics (CFD) is an aspect of multiphysics system analysis that simulates the behavior of fluids and their thermodynamic properties using numerical models. Cadence’s CFD suite includes application areas such as propulsion, aerodynamics, hydrodynamics, and combustion. What makes CFD platforms especially pivotal is their ability to adapt to specific instances of additional physical phenomena.

Cadence’s primary CFD products include:

Fidelity CFD Solution – Provides a streamlined CFD workflow for design, multidisciplinary analysis, and optimization in a single environment. The Cadence Fidelity CFD software is a scalable Cadence CFD solution that provides technology beyond the Omnis end-to-end CFD workflow and Pointwise legacy meshing. For over a decade, the CFD industry has recognized that progress in three vital areas has plateaued: numerical algorithms, modeling of turbulent and separated flow, and the exploitation of HPC assets. Fidelity CFD makes strides in all three; the two most unique aspects are its high-order solver and the first steps toward integrating the Omnis and Pointwise meshing technologies into a single, unique platform while also advancing them separately. The Fidelity high-order solver can provide 10 times the accuracy of classic flow solvers, and 3 times mesh speedup using the Pointwise solution within Fidelity CFD.

Fidelity Pointwise CFD Mesh Generation – Utilizes advanced mesh generation techniques as well as geometry model preparation capabilities for high fidelity characterization of fluids. It is well known that meshing is the most time-intensive part of the CFD workflow with one of the highest impacts, but is vital to ensuring high-accuracy and high-efficiency CFD simulations moving forward. Beyond meshing, however, Fidelity Pointwise can integrate into just about any CFD simulation workflow. Through its mesh export and import tools and pre-built relationships with other solvers and simulation tools, Fidelity Pointwise can enhance existing workflows. The entire team dedicated to Fidelity Pointwise is deeply connected to the greater meshing community and is involved in many aspects of the industry and influential guidelines like the CFD 2030 plan

Addifab: Pushing the Boundaries of Additive Manufacturing

 
May 3rd, 2022 by Jeff Rowe

We recently spoke with Lasse Guldborg Staal, CEO, Addifab about his take on his company as well as the state of the additive manufacturing (AM) industry – where it is and where it’s going.

Based in Denmark, Addifab is a global company built on market knowledge and high ambitions. Based on its experience, the company has developed a unique soluble mold tool enabling a process known as Freeform Injection Molding (FIM).

With its innovative Print→Inject→Dissolve process, the Freeform Injection Molding technique is free of any design or material choice limitations. By printing the tool, you can create unseen designs. You can mold unseen products and business potential by injecting virtually any available material before dissolving the molding tool.

Staal kicked things off by saying, “Addifab was founded in 2014, December, 2014, by me and two other co-founders. We have a background in the hearing aid industry, and decided to found Addifab to create better 3D printers for high-precision manufacturing. Early in the life cycle of the company, we got into injection molding, and we now believe it to be the best possible alternative for injection molders wanting to adopt 3D printing for support of their processes.

MCADCafe Interviews Lasse Guldborg Staal, CEO, Addifab

“Injection molders work with plastic materials and normally use metal tools to produce parts. Metal tools are expensive and time consuming to produce. So, what we do with the 3D printing is to create injection mold tooling that is faster and cheaper, and it’s actually also greener than the conventional metal tooling. If you want to have a low cost injection molded prototype, I think the Addifab technology freeform injection molding is probably your best and most cost effective alternative.”

___________________________________________________________________________________

“At Addifab, we are committed to helping innovators capture the full potential of their ideas, and to bring their products to market faster. With Freeform Injection Molding, we deliver on this commitment; start-ups bring their ideas to market using our technology, and global industry leaders adopt our technology to boost their product development.”

Lasse Staal, Chief Executive Officer and Co-founder, Addifab

___________________________________________________________________________________

“What we’ve tried to do with our technology freeform injection molding is to reduce the costs and reduce lead times. We also want to provide injection molders with a new level of design freedom. And for this reason we have created injection mold tooling that is soluble because if you can dissolve your injection mold tooling, you can create geometries that are impossible to mold with any other method.”

Spatial Corp.’s SDKs Help Build Innovative Engineering Software Solutions

 
April 12th, 2022 by Jeff Rowe

We recently spoke with Frédéric Jacqmin, VP Worldwide Business Development, Spatial Corp. about specific recent developments within Spatial and the industry in general.

From its inception in 1986, Spatial, a Dassault Systèmes company, has developed software components – modular software packages that perform a set of specific and related functions. Software components are also known as software development toolkits (SDKs). This class of software is designed to work as a functional component of a larger application, such as CAD, CAM, CAE, and far beyond. The goal of component software is to standardize the interfaces between software components so that they can work together efficiently.

SDKs are used by almost every CAD/CAM vendor in one form or another. Popular host applications include 3D geometric modeling, data translation, visualization, metrology, toolpath generation, and simulation.

In 1986, Spatial had a primary product: ACIS, the first commercially available 3D geometric modeling kernel. Over time, Spatial added other products to its portfolio that enabled independent software vendors (ISVs), primarily in the engineering software industries, for building host applications. These components include extensions and updates to the ACIS modeler, other design and visualization products, as well as acquisitions in translator technology.

MCADCafe Industry Predictions for 2022 – Theorem

 
February 2nd, 2022 by Industry Experts

Will XR and 3D PDF help define your 2022 digital transformation strategy? Let’s look back to move forwards..

Every year you can always count on a wave of new products or concepts that hope to become the next big thing, especially in regards to technology. Some make it, some don’t. The thing is, whilst these new products are new and exciting, they often don’t have a visible ROI to back them up early on, so when it comes to using these products in industry, it can take time for them to gain the confidence of an organisation, especially where they may be perceived as being disruptive, instead of complementary.

Digital transformation

Over the past few years, companies have been concerned with developing their digital transformation strategy- an organisation’s plan of action on how to strategically reposition itself in the digital economy. This looks set to continue as we are constantly moving towards a more and more digitised world. But from an engineering perspective, is there anything that can be realised as a digital ‘game changer’ for an organisation in the next 12 months?
