ASTM Intl.’s ergonomics subcommittee on exoskeleton and exosuits is seeking participants to support the drafting of a new standard for the use of digital human modeling (DHM).
The WK65347 draft standard aims to use DHM tools to understand the physiological and biomechanical effects of exoskeleton and exosuits on the human body resulting from collaborative work. The subcommittee is looking for DHM model builders and users to clarify modeling needs and application details and develop general standard guidelines to use DHM in exoskeleton design and evaluation.
ASTM task group leader Dr. Bochen Jia says DHM use will accelerate the pace of safe, ergonomic design of exoskeleton and exosuit technology and reduce manufacturing cost.
“Ideal exoskeleton and exosuit development would use digital modeling tools in addition to human-in-the-loop testing,” says Jia, associate professor of industrial and manufacturing systems engineering at University of Michigan – Dearborn. “This helps ensure the system is consistently considering the internal influence of force, torque, and pressure on the body of the user.”
In addition to new standards, the committee is developing 16 work items to address medical exoskeleton needs in risk assessment, hazard evaluation, safety, and mobility.
The exoskeleton and exosuits committee formed in 2017 to develop globally-relevant voluntary standards for exoskeletons. With a current roster of more than 200 members representing 17 countries, subcommittees address safety, quality, performance, ergonomics, and terminology for systems and components during the product’s full life cycle.

The Land of 10,000 Lakes could be the next state to follow California’s strict emissions rules for cars and trucks. The Minnesota Pollution Control Agency (MPCA) has begun accepting comments on final rules to adopt California Air Resources Board (CARB) rules that set stricter-than-federal standards on vehicle emissions and mandate higher percentages of zero-emissions vehicles such as electric vehicles (EVs).
“If Washington won’t lead on climate, Minnesota will,” Gov. Tim Walz said in 2019 when the state announced plans to adopt California standards. Fierce opposition from Republican lawmakers slowed Walz’ plans, but the initiative has inched forward, leading to the pollution agency’s recent call for comments.
California, 12 other states, and the District of Columbia follow CARB rules, effectively creating two U.S. fuel economy and emissions standards. Automakers and federal regulators have long sought to unify the rules but political changes have interfered. Former President Barack Obama’s 54.5mpg fuel economy standards would have unified federal and California rules, but former President Donald Trump overruled those standards before they were enacted. Trump’s administration planned to set new, much easier economy rules. To standardize rules with California, the plan was to cancel a waiver the state received from the U.S. Environmental Protection Agency (EPA) that allowed it to set tougher standards. Like Obama, Trump ran out of time to lock in his plans as several states sued to block new regulations from becoming official. President Joe Biden says he will reinstitute Obama-era policies, but those rules still must be written and go through a lengthy review process.
That leaves CARB free to enact rules for itself and the states that follow its mandates, and that list continues to grow. In addition to Minnesota, New Mexico is in the process of adopting California rules, so Minnesota could become the 15th state following stricter mandates and New Mexico No. 16. https://www.pca.state.mn.us
Laservision Automotive leverages artificial intelligence (AI)-based automatic inspection technology to fill a strategic gap between the automotive industry’s currently available inspection technologies and its quality objectives. The open-platform, in-process automatic inspection system offers detailed inspection throughout a 9m2 field of vision (FOV). Laservision performs automatic, CAD-directed calibrated image capture. Image analysis uses algorithms created through machine learning, and inspection results are available in real-time.
The system can inspect virtually any visible product attribute, from the absence of surface scratches and foreign objects and debris (FOD), to stitching orientation.
Electric spindle system
The iSpeed5, fully tool changeable, high-speed electric spindle, 350W (0.5hp) variable-speed system is available with 60,000rpm or 80,000rpm max. speeds. The iSpeed5 controller can run multiple motor spindles at different parameters and can be integrated with a machine tool CNC control. The system eliminates external motor cords or air lines, allowing continuous, lights-out, high-speed machining. The motor spindle(s) connect to the controller through a constant clean stop block. The iSpeed5 guarantees less than 1µm TIR. Spindles are available in most CAT, BT, and HSK tapers.

The Precision Twist Drill (PTD) HX combines the toughness of a high-strength steel (HSS) substrate with a 135° split-point design to reduce thrust requirements and eliminate walking while providing greater strength and rigidity than general purpose drills. Users achieve increased efficiency and better tool life, reducing cost per hole.
The PTD HX can deliver up to 70% more holes in moderate conditions than standard offerings, delivers 18% more holes in heavy conditions, and up to 30% more holes in light conditions.
Flute geometry optimizes chip evacuation, and purple/bronze oxide coating increases wear resistance. The HX is available in HX10 fractional sizes, HX15 letter sizes, and HX18 wire-gauge sizes. Also available is a 29-piece fractional set (sizes 1/16" to 1/2" x 64ths).

Renishaw founders Executive Chairman Sir David McMurtry and Non-Executive Deputy Chairman John Deer plan to sell their holdings in the global manufacturing technology company, prompting Renishaw to consider selling the entire business. Together, the founders (and people connected with them) own approximately 53% of company shares and have expressed a preference for the disposal of their entire shareholding.
Renishaw’s board unanimously agreed to investigate the sale of the company. The board intends to seek a buyer who will respect the unique heritage and culture of the business, its commitment to the local communities where its operations are based, and who will enable the company to continue to prosper long-term.
Since its founding in 1973, Renisahw has grown into one of the world’s leading engineering and scientific technology companies.
UBS is acting as the company’s sole financial adviser and broker for the possible sale.
Parties interested in making an offer for Renishaw should contact UBS. Any interested party will be required to enter into a non-disclosure and standstill agreement before being permitted to participate in the process. Neither the company nor its founders are currently in discussions with any potential offeror.
“We are both grateful for our continued good health, however we recognize that neither of us is getting any younger,” McMurty and Deer say. “Now finding ourselves in our 80s, our thoughts have increasingly turned to considering the future of our shareholdings in the company and how we can actively contribute to securing the future success of the business. With that in mind, we approached the rest of the board to indicate that we felt the time was now right to discuss the best way to achieve this.”
Sir David Grant, senior independent non-executive director, adds, “My fellow directors and I have thoroughly considered various alternatives in partnership with our advisers... The board has unanimously concluded that it would be appropriate to investigate the sale of the company and is therefore launching a formal sale process.” https://www.renishaw.com
Keestrack to buy Goldoni
Belgium-based mining and industrial equipment manufacturer Keestrack is buying Italy’s Goldoni, giving it access to agricultural markets. Keestrack Group President Kees Hoogendoorn says, “After analysing many opportunities we felt personally drawn to Goldoni for its rich traditional family values which are very close to ours. Our goal is to keep this historic brand alive supporting the local economy and employment rates.”
Keestrack plans to restart Goldoni tractor production as soon as possible, using Industry 4.0 principles.
Family-owned Goldoni, founded in 1926, had a 50 million euro turnover in 2018 (nearly $60 million in revenue). It makes cultivators and specialized tractors for orchards and vineyards.
