Tech Tip: How to create high-quality STL files for 3D prints

Have you ever 3D printed a part that had flat spots or faceted surfaces where smooth curves were supposed to be? You are not alone, and it's not your 3D printer's fault. According to Markforged, the culprit is likely a lack of resolution in the STL file used to create the part.

Engineer's Toolbox: How to pin a shaft and hub assembly properly

One of the primary benefits of using a coiled spring pin to affix a hub or gear to a shaft is the coiled pin's ability to prevent hole damage. Another is the coiled pin absorbs wider hole tolerances than any other press-fit pin. This translates to lower total manufacturing costs of the assembly. However, there are a few design guidelines that must be adhered to in order to achieve the maximum strength of the pinned system and prevent damage to the assembly.

What's so special about wave springs?

Don't settle for ordinary springs. Opt for Rotor Clip wave springs. A wave spring is a type of flat wire compression spring characterized by its unique waveform-like structure. Unlike traditional coil springs, wave springs offer an innovative solution to complex engineering challenges, producing forces from bending, not torsion. Their standout feature lies in their ability to compress and expand efficiently while occupying up to 50% less axial space than traditional compression springs. Experience the difference Rotor Clip wave springs can make in your applications today!

Honda makes major investment in Ohio to create new electric vehicle hub

On Oct. 11, Honda announced two major investments in Ohio, including $700 million to re-tool several of its existing auto and powertrain plants for production of electric vehicles and $3.5 billion with LG Energy Solution (LGES) to establish a joint venture (JV) facility to produce the battery modules to power these vehicles, pending final government approvals.

The joint venture battery plant will be located in Ohio's Fayette County, about 40 miles southwest of Columbus.

The announcement, held 45 years to the day after Honda announced its first production facility in Ohio, aims to transform Honda's Marysville Auto Plant (MAP), East Liberty Auto Plant (ELP), and Anna Engine Plant (AEP) for the electrified future, including the creation of over 300 new jobs.

Honda plans to begin production and sales of Honda EVs in North America in 2026, based on its new Honda e:Architecture. The $700 million re-tooling will enable AEP associates to produce the battery case, to be combined with the battery modules from the JV plant on a sub-assembly line at MAP, with the complete battery unit then installed in EVs built by associates at both MAP and ELP.

These Honda facilities, along with the new EV battery plant, will serve as a new EV hub in Ohio and play a key role in developing the company's knowledge and expertise in EV production that will be shared across Honda's North American auto production network. Honda's EV hub will leverage the company's longstanding production, product development, and purchasing operations located in Central Ohio.

As part of its goal to achieve carbon neutrality for all products and corporate activities by 2050, Honda announced a vision to make battery-electric and fuel cell electric vehicles represent 100% of its vehicle sales by 2040 in North America.

Honda produced and sold a record of more than 100,000 electrified vehicles in the U.S. last year, including the Accord Hybrid, CR-V Hybrid, and Insight hybrid sedan. Honda's new investment in its Ohio plants will support production of electric vehicles and EV components.

The JV production facility represents a commitment to invest $3.5 billion in Fayette County, OH, and will employ 2,200 associates, who will produce pouch-type batteries to be provided to Honda plants for EV production.

Pending regulatory approvals, the joint venture between Honda and LGES will be established in 2022, with the overall investment projected to reach $4.4 billion. The two companies plan to begin construction in Fayette County in early 2023 in order to complete the new production facility by the end of 2024. This will enable the start of mass production of battery modules using advanced pouch-type, Li-ion cells by the end of 2025, with an annual production capacity of approximately 40 GWh.
