What is the short ride in a fast machine?
Short Ride in a Fast Machine, orchestral fanfare by American composer John Adams that evokes the excitement-cum-terror of a late-night thrill ride in a sports car. The piece was composed in 1986 as an opener for a summer festival given by the Pittsburgh Symphony.
When did John Adams write short ride in a fast machine?
John Adams completed Short Ride in a Fast Machine in 1986. He applies the description fanfare for orchestra to this work and to the earlier Tromba Lontana (1986). The former is also known as Fanfare for Great Woods because it was commissioned for the Great Woods Festival of the Pittsburgh Symphony Orchestra.
What is high speed machining (HSM)?
High Speed Machining is a machining methodology that focuses on extremely fast but light, low pressure cuts. The result is an overall increase in the material removal rate. This explanation is a good way of separating things that could be considered HSM by default from the stuff that really makes the cut (see what I did there?).
How does high speed machining work?
Ultimately, HSM works on a gradient. It can be done to varying degrees, but the principles can be applied across the spectrum. It’s not just a matter of RPM. The intention with HSM is using high speeds to achieve a high material removal rate. To accomplish this successfully, there are eight pillar concepts that need to be understood. Here they are:
What Is High Speed Machining?
For many people, this term can be a little vague. For all the companies that boast HSM that I’ve worked with, all of them had slightly different definitions of what it meant.
What is high efficiency milling?
High Efficiency Milling is a methodology that focuses on making the cutting tool work as efficiently as possible. Apparently HSM focuses too much on RPM and fast feeds, so HEM is all about maximizing Material Removal Rates (MRR). Essentially, it’s a term that people came up with to add to the preexisting pile of buzzwords in the precision machining industry.
Why is high speed machining so challenging?
Why High Speed Machining is Challenging. Ok, so if you simply crank the speeds and feeds on the controller, very bad things will likely happen. High Speed Machining is all about being able to compensate in other ways. Simply pushing tools harder will make them break.
What are the requirements for HSM cutters?
The cutters used for HSM are different from the ones that you’ll use for more traditional machining. Basic requirements are to match cutter geometry to material needs, stabilize the tool, and maximize rigidity.
What is a high performance aluminum profiler?
A high performance aluminum profiler is very different from a high performance titanium machining center. You need to leverage the right machine against the right workpiece to get the best cycle times.
How many flutes are in a half inch endmill?
It’s common to see half inch endmills with anything from 6 to 10 flutes. There are two major advantages to this.
Do you need a million dollar machine to do high speed machining?
Really, you don’t need to have a million dollar machine to do high speed machining. Modern machines are getting better and better at handling it even at an entry level.

How much does a fax machine cost?
Fax machines can get expensive, mainly because most do several things other than send faxes. You can expect to pay between $30 and $700 for a fax machine. Here’s what you’ll get for your money, depending on how much you want to spend.
What is the function of a fax machine?
All fax machines perform the same basic function: sending one or more printed pages to other fax machines. But modern fax machines can do a lot more, making them much more useful in your home or office. Here are the features we consider essential.
Why do we need a fax machine?
If you need to send faxes on a regular basis, buying a fax machine is the most cost-efficient way to send pages, so long as you find the right model. Because fax capabilities are often bundled with similar technologies like scanning and printing, it can be easy to spend a lot of money on features you don’t need.
Why is my fax machine getting damaged?
Fax machines can get damaged from power outages and electrical surges. Always keep your fax machine plugged into a surge protector.
Do fax machines use phone lines?
Fax machines use traditional phone lines to establish a one-to-one connection with other fax machines. They’re loud, bulky, and boxy, as well as secure, reliable, and the best solution for anyone who sends faxes on a regular basis. If you buy a fax machine, you’ll be responsible for supplying paper, ink, and a phone line, but your cost per page will be lower over the long term than it would be with a web faxing service.
Does every fax machine have a caller ID?
Caller ID: Surprisingly, caller ID isn’t available on every fax machine, although it probably should be. Caller ID makes it easy to see who’s sending you a fax. If you’ll be using your fax machine to receive a lot of faxes, make sure the model you buy supports caller ID.
Is it cheaper to fax from the internet?
While using an internet faxing service is more convenient, it’s both less secure and much more expensive. Most online faxing services also typically ask you to sign a user agreement that gives them the right to read the documents you fax, which is a major concern for those who prefer privacy.
What Is High Speed Machining?
Why High Speed Machining Is Challenging
- Ok, so if you simply crank the speeds and feeds on the controller, very bad things will likely happen. High Speed Machining is all about being able to compensate in other ways. Simply pushing tools harder will make them break. You need to approach this in a well thought out way. Beyond that, there are a few common challenges to High Speed Machining. Here they are: 1. Lot…
1 – Rigidity of Tool and Workpiece
- Vibration is enemy #1 in High Speed Machining. This is often the single greatest challenge when applying this methodology. If you can’t keep your cutter from screaming, your tool life will be horrible and the part will look like garbage, if not scrap. When the cutter engages the workpiece and starts removing material, there’s a chain of connections...
2 – Tool Balancing
- For the shops that are committed to HSM, this is a must. Many toolholders are balanced to a rating of 10,000 RPM off the shelf. Thing is, HSM is often done way above this, usually at 20k RPM and up for aluminum. If the tool isn’t properly balance, the vibration can really damage the machine spindle bearings. It will also significantly reduce tool life and give you a nasty surface fi…
3 – Tool Harmonics Testing
- This has been around for a long time, and it’s just as practical now as when it came out. Some people refer to this as “ring-testing”. Essentially, every tool assembly will have a frequency at which it resonates. When the cutting edge hits the metal, this sends a shock throughout the tool. If this frequency matches poorly with the tool assembly’s frequency, vibration will be amplified i…
4 – Controlled Tool Load
- Even with a balanced tool that’s been ring-tested, you can get extreme vibration. If your tool load is constantly varying while it’s working, you can get huge problems with chatter. This is especially true in tight corners. With a standard linear toolpath, there will be a really high radial engagement as the tool pushes itself into a corner. Typically the cutter contact doubles. This excessive enga…
5 – Chip Thinning
- This is more than just an issue of climb versus conventional (up vs down) milling. By using the low radial depth of cut that peel milling is famous for (if you’re not familiar with this then you really should read that article linked to above) you’ll end up with much smaller, thinner chips. This allows for really While you can definitely use these principles to an extent for soft materials like alumin…
6 – Cutter Selection
- The cutters used for HSM are different from the ones that you’ll use for more traditional machining. Basic requirements are to match cutter geometry to material needs, stabilize the tool, and maximize rigidity. Again, this is a huge topic, but here are the highlights:
7 – Material Understanding
- At the end of the day, you need to understand the material that you’re working with. HSM is different for aluminum compared to titanium. For example, cutter RPM for titanium is usually pretty low for roughing. Often you’ll be running at 200 SFM or so. For the finishing, though, the speed can be cranked up considerably. Commonly you’ll be finishing at 300 SFM or higher. In all …
8 – Machine Requirements
- Really, you don’t need to have a million dollar machine to do high speed machining. Modern machines are getting better and better at handling it even at an entry level. Don’t get me wrong. The big expensive machines are amazing. The Makino Mag 3 is an aluminum profiler that costs a pile of cash (or good credit) and it’s an absolute beast. I’ve worked on a massive Cincinatti gantr…
