Reverse Engineering With NX

Reverse engineering provides companies with a quick and easy way to analyze data from a physical product. NX gives users a way to do that with the option to import .stl files—files typically created by scanning an object with a light scanner—into the program. Users can take a physical object and can create a model of it using a scanner.

Using a light scanner, a physical object is processed into a .stl file. Then, an engineer in the office can import the raw data into NX using a tool called Convergent Bodies. With this feature, NX directly creates a solid body model from the scan. With this new model, the user can run an FEA or CFD on the product to improve the original design.

However, the process is not so easy sometimes. When scanning, there is a possibility that the raw data can get mixed up and create a surface with holes in it. If this happens, NX can still take the scan and create a solid model with a bit of extra work. The user can take the scan and import it as an NX file instead of a Convergent Body. In this process, the user must create the surfaces by hand, stitching them together using a variety of tools such as Rapid Surfacing, Sew, and Bridges. With some additional effort, the user can still create a solid body from what was once a jumbled bunch of surfaces.

Reverse engineering is an important part of today’s tech industry. NX offers a quick and easy way to scan and then run tests on imported models with Convergent Bodies. Even if the scan did not import well from the .stl format, the user can perform additional steps to create a solid body by importing the file in the NX format. Siemens NX offers a wide variety of tools to utilize for reverse engineering.

Learning NX Through Hands on Experience

I’m Joselyn Patterson. I’m a junior in mechanical engineering at Missouri University of Science and Technology and a member of the VMH Dream Team Internship Program for the summer of 2018. Last week, I had the exciting opportunity to attend FSAE Lincoln as a member of my college’s team. We were happy to place 9th in the competition out of approximately 80 teams in the internal combustion (IC) division.

Now, you must be wondering what it takes for students to design and then build one of these cars. Around the beginning of the fall semester, the team’s project engineers and leaders get together to begin the design process. To help streamline this, we use Siemens NX. Everyone starts brainstorming their ideas using what we have learned in our classes and them applying it to a race car. Once we have basic ideas, we start modeling in NX. The software allows us to make quick revisions and edits to our designs. Then, once a simple model has been created, we put our designs into an assembly that we call the master model. With this, we can see how parts fit together for better or worse. If something won’t quite fit in the car, we as project engineers could make quick changes to fix overlaps and errors.

NX also has other features that come in handy when designing the car. The chief engineer can use NX’s FEA tools to do a stress analysis of features like the frame of the car, manufacturing engineers can take a 3D shape and convert it into a sheet metal flat pattern for water jetting, and the aerodynamics group can set up an aerodynamic analysis of the wing they designed. These are only a few examples of what we as a team do with NX, and it only scraped the surface of what is possible with the software.

As a team, we use NX to do a variety of things that help us come together and build a fantastic car for competitions. Our engineering classes give us the base we need, and NX helps us make it all possible.

Okuma Winter Showcase to feature economical approach to 5-axis machining

The part chosen for the demonstration is representative of landing gear components used in the aerospace industry.

One of the key demonstrations at the 2017 Okuma Partners in THINC Winter Showcase, which will be held in Charlotte, North Carolina, Dec. 5-6, 2017, will feature a modular approach to enable manufacturers to generate high-precision 5-axis parts without investing in a dedicated 5-axis machining center.

The part chosen is a representative aerospace landing gear component and will use the combined products and capabilities of Okuma, which will supply an Okuma GENOS M56O-V machining center, Hainbuch America (precision workholding), Kennametal (tooling), Haimer-USA (shrink fit toolholders), MP Systems (high-pressure coolant and chiller systems), Lyndex-Nikken (5-axis rotary tables), Blaser Swisslube (mineral oil-based coolant), and Siemens PL (systems software).

According to Wade Anderson, Okuma Product Specialist and Tech Center Manager: “This demonstration, and the others that will be presented, provides a vivid example of the success that can be achieved when companies that are unquestioned leaders in their fields work together to create optimal solutions to defined customer challenges. Much of the current manufacturing environment is characterized by the need for complex parts produced in small-to-medium-batch quantities. As parts requiring 5-axis machining have become more in demand, manufacturers are faced with the problem of justifying a dedicated 5-axis machine for a limited number of parts or parts families. Working together, our Partners in THINC have devised a solution that will enable their customers to achieve 5-axis capability and high precision without incurring a prohibitive financial commitment.”

Landing gear part for demo

John Soukup, team leader and regional sales manager (Southeast) at Hainbuch America Corp., comments: “The part that we chose for this demonstration is representative of landing gear components used in the aerospace industry. Constructed of 7075 T-6 heat treated aluminum, the part will be clamped on the ID by a Hainbuch MANDO Adapt workholding system affixed to an 8″ Nikken 5-axis rotary table. The Hainbuch system can be used for both ID and OD applications. The ID application features a system that incorporates both hardened steel clamps and patented elastomer segments that provide maximum clamping force without marring the part finish. The Nikken rotary table is equipped with a carbide worm screw and an iron-nitride worm wheel that hold accuracies of +4 sec.”

The Kennametal tooling package includes the 7792 high-feed cutters with 6mm inserts, carbide end mills with TiB2 coating, a Romicron boring system for the large bore application, and drills of various diameters. Comprehensive tool management will be achieved through the use of Kennametal’s NOVO digital tools. Tooling will be equipped for delivery of high-pressure coolant.

Precision performance will be ensured through the use of Haimer shrink-fit toolholders and balancing equipment. Due to the incorporation of induction coil heating, the Haimer system delivers more than 2x the clamping force of the nearest competitor. The balancing process reduces vibration and results in longer tooling life, better finishes, and improved boring performance.

For the demonstration, Blaser Swisslube has selected Vasco 6000, an ester-based Liquid Tool chosen for its effectiveness in high heat hard machining operations. A high-pressure coolant and chiller system from MP Systems operating at 1000psi and 8gpm will facilitate faster cutting and drilling by efficiently evacuating chips while maintaining thermal control to prevent distortion.

Siemens PL (Product Lifecycle) NX, an integrated CAD and CAM platform, will ensure correct geometries and provide full digital modeling capabilities. In the event of any changes, the system will reconfigure tool paths and ancillary modifications.

Despite the seeming complexity of the system, the entire 5-axis modification can be easily removed from the machine table and stored for further use.

Anderson states, “This is the sixth year of our Partners in THINC Winter Showcase, and over that time we have seen how, working together, we not only solve specific application problems but also advance technology as a whole. If I had to summarize why our partnership has worked so well, it is because all of us are intent on delivering ‘the best from the best.’”

Getting to Know NX

My name is Nicholas Lindenfelser. I am a senior in Mechanical Engineering at Iowa State University in Ames, IA. My goal for this experince in the dream team is to learn and become comfortable with NX and Creo by the end of my internship with the Dream Team. I want to complete projects with the other interns to provide real world experience to simulate life as a mechanical engineer in the workplace. I hope to complete models and designs for different companies. By working with Mr. Banks and the other associates in VMH International, I wish to gain experience in this industry and to use this internship to fully progress my learning as a mechanical engineer. By working in VMH, I will be able to learn Creo and NX, which is not widely available at my university. A lot of companies will use Creo or NX to develop models and simulations that are used in the design and manufacturing process. I can develop the skills necessary to progress as a mechanical engineer with the dream team by solving real world engineering problems. I look forward to see what projects I will be assigned as an individual and with the other interns.

Me and What I Hope to Gain From this Internship

I am a senior at Purdue University majoring in electrical engineering and pursuing a minor in physics as well as a certificate in entrepreneurship and innovation. I have been interested in engineering from a very young age and began taking engineering classes in sixth grade. One of the very first things that I learned in the class was what computer aided design was and how to use it. I immediately fell in love with it and knew that I wanted to pursue it for my future career.

This summer at VMH International, I hope to take my knowledge to the next level. Here, I am surrounded by people with a variety of experiences and I want to be able to learn everything I can from them. I want to become familiar with the PLM software and gain valuable experience that I can use in my future career as an engineer. I also hope to learn about the way a company such as VMH functions and how each member of the team contributes to the success of the company as a whole. I have worked in research labs before but actually applying design principles to real world problems in a corporate setting is new to me. I am greatful for this internship opportunity and I look forward to learning a lot.
