SOLIDWORKS SIMULATION TECH TIP: Shrink Fits and Press Fits

When studying shrink fits and press fits, we have a couple of options in SolidWorks Simulation; I would like to explore a couple of them in this post. If we just care about the end result, we can use the "shrink fit" contact sets. This technique is available in linear static as well as non-linear studies. Using the shrink fit option, the solver will attempt directly solve for the deformation of the male/female interface in its final condition.



If we want to evaluate press fit forces and want to see what's happening during the press operation, we will want to use non-linear simulation, which solves for the final answer as well as the steps in between. Here is the force response of a press fit simulation:

SOLIDWORKS COMPOSER TIP: Mirroring Parts in Composer

Recently, I was contacted by a customer that was struggling with creating an opposite-hand version of a part in Composer and wanted to know if it was even possible. The engineers had only provided him with one side; however, both a left-hand version and a right-hand version of the component existed.

Composer *can* do this utilizing the "Symmetrize" function. Symmetrize makes the geometry symmetrical according to the desired point, plane, or axis.  Simply select and copy your geometry, then select "Symmetrize" to create a mirrored version.

I've prepared an example in the short video clip below.



Remember: it's the little things!

    Robots, Fashion, and the Future of Manufacturing: Our Big M/RAPID Recap

    Last week, we had the pleasure of attending the co-located Big M and RAPID conferences at the Cobo Center in Detroit. Although our team spent most of their time at our booth and the rest at the slot car races run by our new friends at Materialise, we did get a little time to wander around and take in the sights.


    Laura with S. Scott Crump, co-founder of Stratasys
    One of the things we wanted to do at the Big M was show the many different facets and uses of 3D printing, from the serious to the fun. It's why we brought with us a little Makerbot, along with a Fortus 250 and Objet30 Pro, which between them cover a wide range of applications from at-home hobby use to large-scale industrial use. 

    It's also why we took this fashion piece from designer Francis Bitonti and reworked the top part into "armor" to be worn by our events coordinator, Laura. One of our SOLIDWORKS engineers took the original model and reworked it to fit Laura's frame, as well as to print on a much larger machine, and our 3D printing team prototyped it until they found the best material for the job. Laura's dress proved quite popular, and a few people even stopped by to try it on themselves, but we're probably most proud to have gotten the attention of Scott Crump, the inventor of FDM and co-founder of Stratasys.

    Bar2D2 by rp+m
    Enough about us though - here are a few cool things we saw at the show.

    One of our customers, rp+m, were a favorite at the show, and it's easy to see why. Just ONE of the many cool things to see at their booth, Bar2D2 here is a robot that dispenses mixed alcoholic beverages; he holds four different fluids, which can be combined to create a variety of mixed drinks on demand. Bar2D2 was created using a variety of 3D printing tech - Fused Deposition Modeling and PolyJet from multiple Stratasys machines, and EOS Direct Metal Laster Sintering.

    He even turns his head and makes the distinctive beep and whistle sounds you might expect! We of course waited until after the show to try his drinks, but maybe next we can cross the pop culture streams and get him to serve us Earl Grey, hot?

    Although we stopped at the stunning art gallery - who wouldn't? - what really caught our attention was a vast array of innovative technologies on display. We briefly mentioned EOS' DMLS when talking about R2D2, but we also saw ultrasonic 3D printing, BAAM (Big Area Additive Manufacturing) from materials like ceramics and fiberglass, metal coatings on FDM parts, and so much more.

    We finished out the week more excited than ever about the future, and the innovations yet to come. If there's one thing we took away from Big M and RAPID, it's that this is a VERY exciting time to be in manufacturing.

    SOLIDWORKS INSPECTION TIP: Multiple Instances on your Inspection Report

    Adding multiple instances to your inspection report where one feature is identified or duplicated on a given part is a snap. Let's look at the example.


    In this example, a 10mm radius is called out in one location and by default will only show up as one item on the inspection report. However, the dimension is typical and somewhat critical to our specific application.
    To add line items to the inspection report, simply change the quantity in the Properties tab (in this example, it was changed to 2). Then right-select the specific dimension in the Characteristic tree above. Here you can specify to "Make characteristic for each instance."
    This will create an indexed item on the inspection report for multiple instances. Give it a try and let me know what you think.
    Remember, it's the little things!

    I Wanna Go Fast - Our 3D Printed Slot Car Race at RAPID

    Our design iterations
    Tuesday night, at the Big M Event/Rapid 2014 manufacturing trade show in Detroit, Funtech Racing participated in the Materialise Slot Car Championships The race featured 24 competitors from corporations such as Ford & GE, local universities such as Northern Illinois & University of Michigan, and resellers of Additive Manufacturing equipment and services. 

    Each team was given the same chassis, but were required to build their own body using 3D Printing and/or Additive Manufacturing.
    As you can see from the photos, we used several different machines: uPrint, Fortus 250, Objet 30 Pro, and our new Objet500 Connex3; we also tried various materials, including the Vero color options, Tango Black Plus, ABS+ and Vero Clear to build multiple models to verify our design for form fit and function and to improve the overall look of our car.

    Official rendering of Funtech Racing
    After four grueling heats of racing, Funtech Racing qualified for Slot Car Championship Finals by placing in the Top 4.  

    Led by our fearless rookie driver, Nick Licari, Funtech Racing was able to secure a 3RD PLACE finish overall! We were able to achieve all of that despite a nasty collision with our old AMUG friend Jason Lopes from Legacy Effects.

    The Funtech Racing Slot Team

    Driver: Nick Licari (RT Senior Support Team Leader)
    Car Designer: Dan Wiggins (Engineering Manager – Training/Consulting)
    RT Advisor: Ben Hartwig (RT Services Manager)
    Design Consultants:  Elise Hess (Marketing Intern), Laura Gorvokovic (Marketing Event Coordinator)

    We would like to thank Materialise for hosting such a wonderful event and a special thanks to our new friends Jim and "Super" Joe from Nomad Raceways for teaching us the ropes of slot car racing.
