MJ Engineering is part of a team with Hubbard Merrell Engineering and Vertical Solutions working together to improve a swing ride that operates at various youth camps across the country. The attraction lifts up to 3 passengers to the release point and holds them until they actuate the mechanical release themselves. Once released, the riders swing down through the station and up the other side; continuing the back and forth swinging motion until coming to rest at the load/unload station. The biggest problem the camps are having is that the current electric winches are failing prematurely. The current winches are no longer available and the replacement unit is significantly slower than the original system, reducing patron throughput. Additionally, the camp wanted to improve the safety of the overall system while implementing the new hoist system.   

 

Goals
  1. The camp wanted to maintain or improve throughput (i.e. rides per day).
  2. They wanted to find a hoist mechanism that was readily available and could be easily maintained. 
  3. They wanted the upgraded design of the ride to comply with ASTM amusement standards as much as possible.
What did we do?
  1. MJ designed, fabricated & installed a new hoist system to raise the riders to the drop location.  We used a hydraulic power pack to drive a hydraulic hoist that has the speed of the original system with easy to maintain characteristics desired by the camp.
  2. One of our partners designed an update to the rollaway platform, which brings the railing system of the platform into compliance with ASTM ride standards.  Our control system includes a sensor that detects when the platform is stowed out of the swing path.  This fail-safe system would only allow the hoist (and therefore the ride) to operate if the platform was stowed properly.
  3. To prevent the hoist from being raised too far, the MJ control system includes a sensor that detects when the hoist has reached a pre-set maximum lift point.  The hoist is not permitted to raise further when this sensor is activated.

MJ Engineering does a lot of work for numerous companies. We work on everything from coal mines to amusement park rides to robotic systems. This particular case was designing a highly sophisticated system that could scan and upload data about pan usage in a bakery.

~ J. Wand

Problem:

A large pan manufacturing company approached MJ Engineering with a technical issue. They had baking pans that were coming back to them with claims made that the pans weren’t meeting the warranty that the company stated. The company, confident in their product, asked how the pan cycles were being managed. Upon hearing how the current process worked they reached out to us and asked if we could help them. The goal was to create a system to help with the pan life cycle tracking. 

 Solution:

To solve this problem, the Pan Tracking System was born. The Pan Tracking System reads a laser-etched code on the bottom of each pan and keeps a log of it. The log is eventually uploaded to an FTP site where it is compiled and both the pan manufacturer and bakery can see all of the tracking data. The main goal of this System was to track pan usage and lifespans. 

How does this work? The pan comes into the Pan Tracker and the system has a camera mounted on it to read the barcode. Each time a pan passes by the Pan Tracker system, a sensor is triggered to activate the scanners to read the code on the pan.  Every pan code is logged as it passes by the Pan Tracking system. After the data is collected for two hours the log file can be uploaded to an ftp site where it is compiled onto a website where the information can be examined to determine the usage. 

Result:

The result was that the company determined that in fact the pans were meeting the warranty. Now they actually have the data to prove it though. The company is able to track the amount of usage of 1 pan and compare it to another pan in the same set to make sure usage numbers are balanced appropriately. This makes tracking the pans exponentially easier and more efficient. The system is easy to run and can be installed by a knowledgeable in-house maintenance crew with the easy to follow instructions provided.

Challenges:

There were a few challenges to work around in this project. The biggest problem encountered in this process was actually getting the codes onto the pans. This was because of a combination of a few things. The original plan was to use adhesive stickers with a barcode to stick onto the pans. However, the stickers fell off after high numbers of heat cycles. Which led us to have to try something new.  The result was to laser etch the code onto the actual pan. This prevents the code from falling off.

What Does This Mean to You?

Neither CNC machining nor 3D printing is a new technology. Computer Numerical Control (CNC) has been around since the 1950s, while 3D printing was invented in the mid-1980s. But both technologies are in increasing use today. CNC has become one of the dominant machining methods, with CNC lathes, mills, and routers fast becoming the standard.

As for 3D printing, technology has taken off in recent decades years. With its ability to produce almost any shape, many manufacturers have started to ask about the exact relationship between CNC machining and 3D printing. How do the two technologies work? Can they be used together? Will it ever be possible, or practical, to abandon CNC altogether for 3D printing?

In this article, we’ll look at some of those questions, and suggest some ways that a manufacturer could use both methods in conjunction.

Similar goals, different methods

Both CNC and 3D printing are machining manufacturing techniques, but they take a radically different approach. CNC is a subtractive process whereas 3D printing is an additive process. With CNC, Tto make a cylinder, for example, you might begin with a vaguely rectangular shape, then use a lathe to machine away excess material until the workpiece was cylindrical. The resulting piece will be smaller than the one you began with; you’ve removed material to make the part.

3D printing is the exact opposite. With 3D printing, you begin with no shape at all – simply the printer itself and a metal powder as raw material. The powder is used to slowly build apart from the ground up, adding material layer by layer.

Additive machining manufacturing provides a whole new approach for manufacturers. 3D printing can produce almost any shape, including geometries that might be difficult to achieve through subtractive machining. The potential applications for 3D printing are nearly limitless, with special potential for prototyping and R&D.

Pros and cons

So why not simply abandon CNC subtractive machining-manufacturing and move everything over to 3D printing? Why not stop cutting metal parts (subtractive machining-manufacturing) and only build them instead (additive machining manufacturing)?

Unfortunately, 3D printing does have some drawbacks. First and foremost, the process is quite slow – far slower than the various subtractive machining processes. Large-scale, industrial-sized projects would require a much longer time to build than to cut, particularly if there is a large number of parts to produce. Thus, one of the first questions many manufacturers use to determine the correct method to use is simply to ask, “how many parts do I need?” If the answer is a large number, CNC is likely to be much faster and more efficient. 3D printing also produces parts with much larger tolerances than CNC machining, meaning the parts can be a bit rougher and still in need of finishing. 

Two are stronger than one

The greatest potential for both methods comes when they are used in conjunction with each other. For individual parts, 3D printing provides a way to produce one-off or small runs of parts with geometries that would be difficult to cut on a CNC machine. After the 3D printing is complete, the same part could then be subtractively machined via CNC to finish surfaces, insert threaded holes, or any number of other machining steps.

The two methods can also be used in the overall workflow. 3D printings excel at producing prototypes and models, parts that are often one-off productions or require small numbers, and where the time pressure is not great. Once a part has been prototyped and the design refined, a CNC program can be made that allows operators to produce the part in far greater quantities on a CNC lathe or mill.

Used in this way, the manufacturing process starts with additive machining manufacturing and then moves to subtractive machining-manufacturing, to produce even a difficult or completely new part with tight tolerances.

Back and forth

Using CNC machining and 3D printing isn’t a matter of transitioning entirely from one to another, but of using both technologies at once. In the real world, that means being flexible and deciding on a case-by-case basis which method is best for a given part.

Overview

MJ Engineering collaborated with Focused Technologies to develop the award-winning (Best Maintenance of Way Product 2020) and patented SpikeEase railroad spike remover.  The SpikeEase project originated as a college senior design project, which MJ Engineering completely redesigned to make stronger, lighter, more powerful, more ergonomic, and easier to use.  This product utilizes a customized acme screw and acme nut that when turned by an off-the-shelf impact wrench uses leverage to pull the spike out of the tie. This product is an investment in safety and productivity that pays for itself by increasing production, reducing injuries, and eliminating the need for hydraulic equipment or claw bars. The SpikeEase is designed to be the lightest, easiest, and most eco-friendly spike remover in the world.

According to Focused Technology Solutions, the SpikeEase is the world’s most advanced battery-operated spike remover.  Eliminating the need for hydraulic systems means un-tethering employees from service vehicles, heavy hoses, and expensive hydraulic power units.

Goals

  1. Design a battery-powered spike remover
  2. Improve maximum pull force
  3. Reduce the cost of and weight of the SpikeEase.
  4. Improve the ergonomics of using the SpikeEase in the field every day.
  5. Improve the strength and useful life of the SpikeEase

Specifications

  • Weighs in at 30 pounds (not including drill or battery) 
  • 3-7 seconds per spike removal
  • A rechargeable battery pack and a commercially available drill
  • Easy to transport anywhere the rail takes you  
  • No hydraulic system to risk leaks and environmental hazards. 

 

At MJ Engineering, we don’t settle for a quick fix; we work to solve the root problem. That is exactly what we did when one of the largest pan manufacturers in the US approached us looking for a solution to a problem their bakery customers faced. 

Problem: Malfunction Due to Overuse 

The problem was, after so many baking cycles, the non-stick coating used on the pans wore off. The quick fix was for the bakery to send those pans back to the manufacturer for recoating. The better fix was for the manufacturer to contact MJ Engineering. As MJ Engineering worked on a custom solution, it became clear that the coating was not the direct source of the problem.

 

The coating wore off naturally when it exceeded a certain number of thermal cycles. In other words, the pans were malfunctioning due to overuse. Many of the bakery owners were only using a portion of the baking pans they received from the manufacturer because there was no way to track them.

Solution: Vision Sensor Technology 

MJ Engineering resolved that problem by designing a tracking system that could read a laser-etched code on the bottom of each pan as it passed over a vision sensor on its way through the oven. Then MJ Engineering sends the data to the manufacturer’s custom software that allows the bakeries to interpret the pan usage data from the vision inspection equipment to determine when to recoat or switch pans.  

 

“The baking pan tracker effectively does two things,” said Richard Wand, owner of MJ Engineering. “It allows bakers to understand their pan management and rotation schedules through the compiled data from the scanner, and it also allows them to see that their pans are meeting the warranty life that the manufacturer stands by.”

Results: Entire System Working More Efficiently

MJ’s engineers developed a way to use common, easily accessible components to integrate with MJ Engineering’s proprietary tracking software.

Now, bakery personnel can install new pan trackers—about the size of a breadbox—in a pinch with simple tools. 

As Keith Kneidel, project manager for MJ Engineering, said, “We’ve taken the technologies that are there and married everything to a complete system: the camera technology (made by SICK), the PLC, or user-interface computer, the screen, and the FTP to get the data back to the manufacturer.” All the individually sourced components work together to allow the bakers to focus on baking.

 

Not only are buns no longer sticking to pans, but the data being gathered via automated inspection is also providing the pan manufacturer with up-to-date information on their pan’s durability and coating competency. The bakery owners can log onto an online portal for real-time updates on their pans. Buns are going into customers’ mouths instead of trash cans.

The Solution to Your Problem May Be A Tracking System

The ultimate solution to the pan problem turned out to be much larger than just recoating.

 

In fact, MJ Engineering’s pan tracking system not only extended the life of each pan, but also the relationship with the pan manufacturer and the bakery owners. Reducing product waste and shipping time between the bakeries and the manufacturer also made MJ Engineering’s system a win for the pan manufacturer.
