Understanding Electric Discharge Machining (EDM):
EDM, sometimes referred to as spark erosion, is a machining technique that employs precisely controlled electrical discharges to erode and shape workpieces. Its effectiveness shines particularly when working with materials that are challenging to machine using conventional methods. EDM enables the creation of intricate shapes and precision machining of complex geometries.
How EDM Operates:
The EDM process revolves around controlled electrical discharges between the tool (electrode) and the workpiece, both submerged in dielectric fluid. This process can be divided into several stages:
Electrode Selection: An appropriate electrode material is chosen based on the workpiece material and desired machining outcomes. The electrode serves as a conductive tool that interacts with the workpiece during the process.
Dielectric Fluid Tank: The machining process occurs within a dielectric fluid, often an oil-based solution or deionized water. The dielectric fluid acts as a medium for electrical discharges and dissipates heat generated during the process.
Electrical Discharges: The tool and workpiece are immersed in the dielectric fluid. Controlled electrical discharges occur between them, leading to localized material melting and vaporization.
Formation of Erosion Channel: As the discharges continue, material is eroded from both the tool and the workpiece, shaping a cavity or channel with the desired geometry.
Cooling and Flushing: The dielectric fluid also serves to cool the process and wash away eroded particles. This prevents excessive heat accumulation and maintains process stability.
Types of EDM:

5 Health Benefits of Regular Pedicures

There’s nothing quite like a pedicure to keep your feet looking and feeling their best, but did you know that pedicures do more than simply enhance the appearance of your feet? Many people don’t realize that regular pedicures can come with a wide range of health benefits that can promote the well-being of your feet, so here are some ways that your routine pedicure keeps both your toenails and feet in the best condition possible!
Smoother Skin
One of the biggest misconceptions about pedicures is that they only cater to and look after your toenails. While you’ll definitely be leaving each session with a fresh coat of nail polish, your pedicure can also do wonders for the health of your skin. Aside from trimming and shaping your nails and cuticles, you’ll notice that your nail technician also dedicates a few steps to the skin of your feet.
After inspecting your feet and looking for any issues or imperfections that may need to be addressed, your technician will work on an exfoliating scrub to remove any dead skin cells. This step may also be aided by a foot file, which can be used to buff away any calluses and other problem areas manually.
Softer Skin
After your nail technician addresses all the problem areas of your feet and removes any unwanted dead skin cells, he or she will often massage in a moisturizing product, such as lotion, cream, or butter, to ensure that your skin is properly moisturized. These products contain skin-loving ingredients that will ensure that your feet have everything they need to look and feel their best so that you can walk out of your pedicure with a renewed sense of confidence.
Healthier Nails
After your pedicure session, your nails will not only look better due to the fresh coat of nail polish, but they’ll also be healthier and stronger. This is because your nail technician takes their time to ensure that your nails are properly looked after through steps that include deep cleaning, nail trimming, nail filing, and cuticle care. All of these things work together to prevent issues like ingrown nails from occurring, all the while improving the appearance of your nails.
Increased Blood Circulation
While the specific steps included in your pedicure will depend on the beauty salon, most pedicures will have a massage step somewhere in the mix. One of the often overlooked benefits of these massages is the increased blood circulation, which can deliver more nutrients and oxygen to your feet and nails, promoting their health and appearance. Aside from that, better blood flow means reduced tension and soreness, as well as better distributed heat throughout your body.
Reduced Infections
A significant amount of dirt and bacteria can build up on your feet without you even realizing it, but pedicures can be a great way to prevent these from happening in the first place. The exfoliation step of a pedicure removes dead skin cells as well as all the debris that may have accumulated underneath, and the deep cleaning of your toenails and cuticles also gets rid of any impurities that may have slipped beneath them, which can stop infections from happening.
These are some of the many health benefits that you can look forward to at your next pedicure appointment. However, it’s worth noting that you need to book regular sessions to truly reap all the rewards. This can be difficult, especially when you don’t feel like driving to your nearest nail salon after a long day, but the good news is that you can enjoy the salon experience in the comfort of your own home with a home pedicure service.
