I’m writing this column a week after attending a March 25 webinar about the effects of the coronavirus on the manufacturing industry. Although the presented data will be out of date by the time this is published, the pandemic was not the point. The broader takeaway was the potentially vast power of widely shared machine utilization data for improving business planning and benchmarking, whatever the economic situation.
The power of this dataset is that it is available in real time, in this case through webinar host MachineMetrics’ multi-tenant cloud platform. Taken from thousands of machines in every sector of the industry, the anonymous, aggregated data often reveals trends and insights prior to leading Deep Hole Drilling Inserts economic indicators such as industrial production and the Purchasing Managers’ Index (PMI), says company co-founder Bill Bither.
He went on to show graphs of utilization and downtime data illustrating steep declines in the automotive industry after the “Big 3” automakers shut down only days before. “We have the real-time element — the pulse of manufacturing,” he said.
Quarantined at home, my first reaction was that anyone could see things are changing, and that the pandemic’s grip on the economy has only begun to tighten. However, the potential in this data was just as obvious, and other insights are already coming into focus. For instance, during a phone conversation a week after the webinar (which was the first in a planned series of presentations on the impact of the virus),Carbide Grooving Inserts Mr. Bither speculated that an uptick in automotive utilization might be a result of manufacturers retooling for medical supplies. Pandemics aside, less obvious correlations and trends that might guide manufacturers’ planning are likely to show up here first.
Perhaps more importantly, revealing broad economic trends is only a beneficial byproduct of the company’s data collection. “The real benefit for the machine shop is how this data correlates to their own operations,” Mr. Bither said.
For instance, MachineMetrics’ regular reports reveal that having a “case of the Mondays” is a very real phenomenon. The aggregate data show that, in general, machine utilization tends to be lowest on that day before peaking by Wednesday and dropping again into the weekend. This can also be narrowed to hours of the day, and extrapolated to the entire calendar year. In one case, proving a gut instinct with real data led one MachineMetrics customer to eliminate Columbus day and extend the Christmas holiday instead.
Finding surprises in the data is even more valuable, Mr. Bither said, pointing out that shops’ actual average machine utilization, which is generally around 25%, pales in comparison to the 60% or greater that most users assume prior to implementing company’s machine monitoring system. Where does a shop stand in relation to other businesses in machine utilization as a whole, or, more specifically, time lost to changeovers? Which machine types experience more downtime on average, and why is that? Are shops in the Northeast experiencing higher utilization rates than those in other regions?
MachineMetrics aims to make such insights available at any time to everyone via regular “State of the Industry” reports published online, Mr. Bither said. These reports would not be possible without the system’s users, all of which must opt in. Beyond being willing to share data, they are obviously comfortable with machine monitoring generally, as well as cloud computing and, if that is any indication, other tools of data-driven manufacturing. Data democratization, and the benefits all stand to share, begins with individual shops understanding that in many ways, they’re all in it together.

CNC: Circularity and Cylindricity – the difference
Circularity: Every circular cross section of the part must lie between two concentric circles spaced the ‘circularity’ distance apart. In this example, the circularity is 0.25 mm. All cross sections (like A-A and B-B in the figure) must lie within two circles 0.25 mm apart. Circularity is 2-dimensional. You are only checking to see if the cross sections are OK, not whether their centres lie on a straight line.
Cylindricity: Every circular cross section of the cylinder must lie between two concentric cylindersspaced the ‘cylindricity’ distance apart. In this example, the cylindricity is 0.03 mm. All cross sections (like A-A and B-B in the figure) must lie within these two cylinders 0.03 mm apart. Cylindricity is 3-dimensional. You are checking to see if the cross sections are ok AND that they lie on a straight line.
The rod in the picture below might be OK for circularity, but will not be OK for cylindricity.
Circularity can also apply to spheres and cones, while cylindricity applies only to cylinders.
This post was prompted by a suggestion of Mr. K. Vijayakumar in my last post.

Donkey or Mule ? My perennial confusion
I saw these animals on an under-repair highway recently, driving to North Karnataka for a short holiday. I wondered whether they were donkeys or mules. I’m always confused about this, and did some reading on the internet after I got home. Turns out they were donkeys.
The mule is the offspring of a female horse and a male donkey, kind of mid-way between a horse and donkey physically. It is sterile, and cannot produce any offspring. The horse and donkey belong to Lathe Inserts two different species, and the mule is a hybrid that does not belong to a species of its own – even its scientific name indicates that it is a hybrid (I also just learnt that the x sign in a hybrid name indicates the link between the parents – never knew that a bunch of donkeys could teach me so much).
Donkey: Equus africanus asinus
Horse: Equus caballus
Mule: Equus asinus × Equus caballus
Mules work alongside soldiers in high altitude areas on India’s borders, and are used to transport stores, heavy artillery and ammunition where no vehicle can go. An army mule can carry 50-60 kg upto a distance of 25 km. Mules are sure footed (hence can walk along narrow mountain tracks), intelligent, have a good memory Cutting Tool Inserts for routes.
Charles Darwin expressed his admiration for the mule beautifully: “The mule always appears to me a most surprising animal. That a hybrid should possess more reason, memory, obstinacy, social affection, powers of muscular endurance, and length of life, than either of its parents, seems to indicate that art has here outdone nature.”

Companies that design and manufacture plastic or metal parts will often require rapid machining services at some point during product development.
This article looks at the ins and outs of the manufacturing process and why it is so important.
What is rapid machining?
Rapid machining is the machining of parts and prototypes with an explicit focus on reducing the time taken to make the parts. It usually involves CNC machining (including milling, turning, etc.) but may also include manual machining for simple parts.
Machining can be expedited in various ways. Depending on the customer’s requirements, rapid machining may involve increased use of high-torque machines and roughing techniques in order to speed up material removal. It may also involve easy-to-machine materials like aluminum alloys over materials that require more time to machine.
Although not mutually exclusive, rapid machining can be seen as a counterpoint to precision machining, which prioritizes accuracy and detail over speed.
Pros and cons
Rapid machining is an essential tool for rapid prototyping, product development, low-volume manufacturing and custom parts. However, it is not suitable for all manufacturing jobs.
These are some of the advantages and disadvantages of rapid machining:
Pros
The fastest way to produce parts with CNC machining equipment
Iterates prototypes quickly to speed up product development
Easy to fabricate multiple versions of a part for mechanical testing etc.
Faster time-to-market
Makes stronger parts compared to other high-speed processes like 3D printing
No minimum order quantity
No tooling or startup costs
Compatible with a range of metals and plastics
Range of surface finishing options
Scalable since CNC machining is suitable for production at a later time
Cons
Lower quality than precision machining
Less geometrical freedom than 3D printing
Slower than molding processes for high-volume orders (100+)
How rapid machining speeds up product development and reduces time-to-market?
For decades, rapid machining has been a go-to process for product designers looking to move their product from one stage of development to the next.
Rapid machined prototypes can be used for testing and evaluation, and it is easy to fabricate multiple iterations of a design for comparative analysis. Some rapid machined parts are even suitable for end-use.
It’s easy to see why designers engineers keep turning to rapid machining for instant parts. In this day and age, most parts are designed using CAD software, and the exported design files can be processed by CNC machines with minimal preparation. This closes the time gap between finishing a prototype design and receiving the finished part.
And the process is often repeated several times. If product designers are ordering rapid machined prototypes for testing, they may need to tweak their designs and build several more iterations before the part is ready for production.
Rapid machining also provides prototypes that are similar to end-use parts in terms of quality, mechanical performance, and appearance. Other prototyping processes like 3D printing and Carbide Inserts manual assembly have their own unique advantages, but if a part will eventually be manufactured with a CNC machine, a machined prototype will obviously be more representative of the machined final part.
Committing to a consistent manufacturing process provides obvious time advantages. If a 3D printed prototype has to be redesigned into a machinable end-use part, a whole new stage of design is added to the overall process. No such stage is required for rapid machined prototypes.
A product development workflow using rapid machining may therefore go something along these lines:
Concept
CAD part design
Early-stage conceptual prototype(s) via rapid machining
Pre-production prototype(s) via precision machining
Presentation, marketing, etc.
Production
Distribution
Ultimately, faster product development and shorter time-to-market give companies a competitive edge and leads to a greater chance of market success.
What level of quality should I expect from rapid machining?
Rapid machining is most frequently used as a prototyping process. As such, customers should remember that there are other options (precision machining, for example) that may be better suited to high-detail parts that demand tight tolerances. As its name suggests, rapid machining prioritizes speed over other factors.
That being said, rapid machining can produce professional-grade parts and prototypes to a very high standard.
Ordering parts from a rapid machining specialist ultimately allows the customer to stipulate the level of quality of required, by specifying tolerances and choosing a material of suitable quality and price.
Loose tolerances, simple designs and the use of high-machinability materials allow machinists to make the parts faster, giving a lower priority to part quality. During prototyping and product development, this is usually a sensible route to take, as professional machinists are still able to make good quality parts while working quickly.
How Estoolcarbide achieves high speeds during rapid machining
Opting for rapid machining is only worthwhile if the machining company actually knows how to get things done efficiently — otherwise, the customer ends up sacrificing quality and getting none of the benefits.
Estoolcarbide is a specialist in rapid machining and has perfected several techniques for getting high-quality parts done fast.
Here are some of the reasons why we machine faster than the competition:
It’s in our nature: Estoolcarbide was established as a rapid prototyping company, and our entire setup — from customer interactions to the factory floor — is optimized for fast turnarounds, whatever the project.
We know which machines to use: Different projects demand different equipment, and rapid machining has its own particular set of machine requirements. For large parts that require large amounts of material removed, we might employ a high-torque 20 kW machine with a 12,000 rpm spindle; for detailed surface finishes, we might use a lower-torque machine with a 24,000 rpm spindle.
We know how to cut quickly: Rapid machining isn’t achieved by just lopping off as much material as possible at once: sometimes it’s faster to make multiple shallow cuts instead of one deep cut. Fast machining involves choosing the right cutting tool and making the right cuts, in addition to using high-end CAM software to determine the most efficient tool paths for a job.
Tight deadlines: Rapid machining or 3D printing?
3D printing has changed the prototyping landscape by allowing users to fabricate one-off parts in a matter of hours. 3D printers can even be operated in offices, reducing the need for traditional factories and machine shops.
Because of the speed and simplicity of 3D printing, some product developers will automatically turn to additive manufacturing over subtractive processes like rapid CNC machining when time is of the essence.
But is 3D printing always the best option for fast-turnaround parts?
For in-house prototyping, there is probably no better rapid solution than 3D printing, since 3D printers require minimal expertise to operate and can print parts in hours. However, a professional rapid machining service may be faster and deliver better results than a comparable 3D printing service.
There are some obvious parallels between rapid machining and 3D printing. Both use digital designs that are turned into G-code, and both are all-in-one solutions that require no tooling or separate machinery.
When choosing between rapid machining and 3D printing, bear the following factors in mind:
Some parts are faster to print; others are faster to machine
Even if 3D printing is faster, it may take a long time to rework a 3D printed prototype into a machined final part
Both metals and plastic can be machined with the same machining equipment; 3D printers only print one or the other
Machined prototypes are usually closer to the final part than printed prototypes
