In developing biorenewable polymers many technical challenges have been overcome by industry only to realize that cost, availability of biobased raw materials, and valued sustainable benefits are even larger barriers. Though several commercial paints claiming biorenewable content have entered the market, their adoption has been modest at best. To truly gain mass adoption by the market, it is theorized that a biorenewable polymer must be capable of delivering valued performance while being sustainably advantaged. Data will be presented on an experimental acrylic emulsion polymer based on biorenewable feedstock that is traceable via Carbon-14 into the actual product which is balanced for performance, relative value, and sustainability. Analysis will include the paint performance versus other petroleum based commercial acrylic, styrene-acrylic, and vinyl-acetate-ethylene copolymer emulsions. Additionally, Life Cycle Inventory Assessment models were developed for these polymers and a comparison of their environmental impacts will be reviewed.

Threading is one of the most important machining processes. It is used to create screw threads, which are used to fasten together materials and components.
Threaded holes are very common in manufacturing. Due to versatility and ease of use, they’re so versatile that they can be found in everything from automobiles to aircraft.
But, tapping threaded holes is not as easy as we think. So, it’s important to learn about all the different machined threading technologies available so you can make the best choice for your projects. The following information will help you understand tapping a threaded hole better.
A threaded hole is a hole that has been threaded or tapped, with internal threads. It is a circular hole used for tapping and drilling processes. For creating threads to the walls of the drilled hole, you can use the tapping process, and it occurs in an area and site where bolts and nuts can not work, such as in metals.
Sometimes threaded holes are also called tapped holes. This type of hole is used when it is necessary to connect two parts together using a fastener such as a screw or a bolt. The threads in the hole provide resistance so that the fastener will not loosen over time and also make it easier to remove the fastener if necessary.
The tapped hole is a type of hole that is used to create internal threads. It is created by drilling a hole in the material and then using a tap to cut threads into the walls of the hole. Tapped holes are commonly found in metal components that need to be secured together, such as in the case of a nut and bolt.
The tapped hole has many similar aspects to a pilot hole. Both are used to create a thread in a workpiece so that a screw or bolt can be inserted. A key difference between the two is that a tapped hole is already threaded and only needs a tool to create the mating thread, while a pilot hole must first be drilled before it can be tapped.
Tapped holes are essential aspects of machine parts, and you can use a CNC machine to add a hole. In the tapping process, you can create threads to the walls of the drilled hole. Machine screw can not create their own threads, If you want to drive a screw into a metal material, you need a tapped hole and make threaded elements add to a CNC machine process.
Each feature will add appropriately to threaded parts, and most threads can choose depending on their features. Let’s us why it is important to create a tapped hole.
1. Connection
If you want to thread a bolt or screw into the metals, it can make it possible to attach two parts with more reliability. Threading can permanently attach a bolt, nut, and screw with a metal.
2. Easy transportation
A tapped hole makes assembling tiny parts and products easy for shipping to reduce labor costs to a great extent.
3. Simple operation
It can provide a place for screw fasteners and tapped holes. You can drive a screw or bolt on metal more easily without making a pilot hole.
You can create threads on the interior side of the drilling hole, and it takes less time than the process of drilling a bolt, a nut, or a screw into wood. Tapping a hole can suit your project’s requirements no matter if you need a through-hole or a blind hole.
It is essential to have straight, good, and proper size holes for threading in the hole-making process. In-state of art machinery drilling (oversize) factor is mostly removed, but it has great importance in the hole-making process, so it is critical to consider how to make a hole before tapping.
A tapped hole was formed using a tap drill bit and a drill bit. A pilot drill bit can make the initial hole, while a tap drill is mostly used to cut the threads in a tapped hole. After inserting a screw, its outer threads(external threads) can wind down into the internal threads. Internal threads can create a tap a bit in a tapped hole.
Some machinists still use the old rules and standards and tap drill charts for a threaded hole. One example of threads is as they use 17/32 die and tap drill for 5/8-11, these percentages of thread sometimes make work more complicated. Therefore, it is necessary to carefully understand the standard of thread and the use of different tapping tools before tapping the hole.
Before making a threaded hole, you can get various options for pilot drill size and tap drill size, find an expert person who understands tap drill and different thread sizes can make a big difference for your project.
There are two types of holes for the definition of threaded holes. Each type of hole demands specific considerations to make sure threaded holes are easy to machine.
Blind hole: This hole has a certain deepness and can not pass through the whole workpiece. Deepness needs to be fixed separately. The bottom of the hole can end on a flat surface or end in a cone.
Through hole or clearance hole: A hole can go through the entire workpiece in a through-hole. The deepness of a through-hole is the thickness of a particular wall. Using a bolt, a screw, and nuts, you should use a through-hole for easy procedure.
The main difference between drilling and tapping is the sequence and performance of functions and drill bit. This process occurs first to make a round and smooth hole using a drill bit, which is called drilling.
The formation of a tapped hole is completed using a tap drill bit and drill bit in which the pilot drill bit initially forms the hole and then can cut the threads by using a tap drill. Taps can handle most types of materials such as aluminum, steel alloy, steel, and cast iron,
This round and smooth hole are made in this process, while on the other side when a hole is drilled, a process of tapping happens to make threads by applying a tap to the interior of the hole.
Except for these processes, creating threads can accomplish and accommodate the outside of a cylindrical object in a die-cut process by using a die. The threads on a bolt are one example of a die-cut.
The main types of taps are Plug tap, Taper tap, and Bottom tap.
These types are used and designed to perform a specific function or purpose and can thread specifically around any hole thrown at them.
A taper tap has a conical tip and a slight angle to the threads, which is also called a chamfer. Usually, the first seven to ten threads aren’t completely formed. The tapered angle of the threads allows the threads to be started much easier than if you started with a bottom tap. This type of tap is generally used for starting a new thread in a hole.
If the hole that needs to be tapped is very large, or if the material is very hard, it is not recommended to use a taper tap. In these cases, it is better to use a spiral point tap instead. Taper taps are also not recommended for blind holes (holes that do not go all the way through the material).
Plug taps occur between a taper and bottom tap, and due to this reason, it is also called a “second tap.” But plug taps need more force for turning as they cut more threads at one time.
Plug taps are the best example to repair threads that require a little fixing. They are perfect for tapping a hole deeper than taper taps thread.
There are a few instances where it is not recommended to use a plug tap. One example is if the hole being tapped is very close to the edge of the material. This is because the tap can easily break if it hits the edge while in use. Additionally, using a plug tap on a very small diameter hole can be difficult and may result in the tap breaking.
The bottom tap is a type of tap that starts from the bottom of the hole. It is used when there is not enough space to start the tap from the top. The bottom tap makes it possible to cut threads all the way to the bottom of a through-hole. This type of tap is also useful for fixing mistakes made while tapping from the top. It is mostly used for:
Threads or threading a shallow blind hole
Deep threads & shallow hole
Tapping a new hole
A bottom tap is a specialized tool and may not be available in all sizes, so it is important to check before beginning a project.
Tapped holes are considered essential to adding mechanical fastened parts with machines. It will be a big damage to the CNC machined parts if you try to add and force a scrap in the wrong way. So, careful considerations and planning before machining a threaded hole is essential and will help you avoid some unnecessary troubles.
You can make an internal thread in tapped holes in two ways:
by using a forming tap
by using a cutting tool
Although both these methods give you the same result, you have to consider some factors to choose one of these methods, such as the size of the threaded hole, machine lathes, hardness of the material, and blind or through-hole.
1: Size of the threaded hole- You can use a forming tap or a traditional cutting tap if the threaded hole is up to M6. You can use a single lip tool to cut the threaded hole more than M6. Because needing the larger tap for cutting threaded holes for more machine horsepower.
2: For Hard materials -You can use a cutting tap for hard and sturdy materials for hard materials. The fluting of the cutting tap provides lubricant to flow down a path and gives metal shavings more space to the cutting edge.
3: For a soft material- Use forming taps for non-ferrous soft metal materials such as brass, lead, steel, and aluminum. Forming taps can create internal threads in softer metals without breaking. This is because the cutting action is slower and more controlled, which helps to prevent damage to the material.
The size of the threads used in CNC machines is of great importance. It greatly affects the whole machining process. You must try to use standard sizes of thread under possible conditions.
There are a few common thread sizes including 1/4-20, 3/8-16, and 1/2-13. Each of these sizes corresponds to a different diameter and pitch, which helps to ensure that the threads will fit properly onto the desired object. Additionally, there are also metric thread sizes. The most common metric sizes are M6 x 1.0, M8 x 1.25, and M10 x 1.5.
The machining process does not require any special machining tool or material when standard thread sizes are used. Moreover, it also helps in reducing the machining lead time and material usage and makes it a cost-effective process.
You must make sure that the threaded hole’s diameter must be within the workpiece or part. The threaded hole’s outer diameter must be larger than the internal diameter. Its means that the internal diameter will be smaller than the outer diameter.
The breakage of the thread may occur through the part’s side if the threaded hole is present close to the edge of a part. The breakage of threading may result in the cutting tool or tap breakage, destroying the surface finish.
It may be tough to machine thread holes into angled surfaces. You can add a threaded hole into an existing angled surface by creating a flat surface by machining pockets. The threaded hole is added from this flat surface.
But, in case no angled surface is present, then firstly, you have to do an addition of the threaded hole to the part before the machining of the angled surface. You must make sure that the depth of the threaded hole must meet the design after adding the angled surface.
The threaded holes are divided into two types. Both types of holes required definite considerations during designing the part. It is done to ensure the machining of both threaded holes.
Moreover, it also prevents the interference of threaded holes with other parts. The followings are the main types of threaded holes:
The blind threaded holes do not go completely through a part, but it goes to specific parts. The blind holes stop after reaching the specific deepness. If a threaded hole is created using an endmill, then the hole may end on a flat surface. If the hole does not go completely through the material, you know it is a drilled hole. But, if it is created using a traditional mill, it may end at a cone. If it is required to extend the full thread to the bottom of the blind threaded hole, it is done using a bottoming tap.
Dimensioning of a blind hole
The hole diameter is listed for the specification of the blind hole. It also requires dimension for controlling the depth. The remaining amount of material is identified, or the hole depth is directly specified to control the depth.
The through-hole goes completely through a part. The threaded holes are present on both sides of the part or workpiece. The part thickness is determined if the cutting tool or the tap reach cannot thread the entire deep hole.
You must consider the following options if the cutting tool or the tap reach cannot thread the single side of the hole.
Keep on adding threads until allowed by the cutting tool or tap. You must note that there is no thread at a portion of the hole.
Keep adding threads on both sides until allowed by cutting tool or tap. You must note that the threads meeting from both sides may not align.
Deep threaded holes present unique machining challenges compared to shallower threaded holes. The increased depth of the threading creates more contact time between the tool and the workpiece, which generates more heat and requires greater cutting force. These factors increase the risk of tool breakage when machining deep threaded holes. To overcome these challenges, special care must be taken when selecting and using cutting tools, and the machining process must be closely monitored to ensure that tool breakage does not occur.
When it comes to tapping threaded holes, it is important to have a complete understanding of the manufacturing process. This way, you can ensure that the parts you produce are of high quality. While it may seem a little complicated, it is best to consult with experts in threading techniques.

CNC machines provide increased productivity and efficiency in a wide range of applications for hobbyists and professional tradesmen. One of the most popular and practical uses of CNC machines is working with aluminum and brass CNC, where the added capability and precision allow complex work to be completed on an accelerated timeline without sacrificing quality.
In some instances, you may not have a choice as to what material you work with, but if you do, aluminum and brass are both great options for several reasons. Here are some key points to know when using a CNC machine to machine aluminum and brass, whether at home or in a professional shop.

Aluminum is a relatively soft yet durable material that is lightweight and malleable. It is non-magnetic, meaning it doesn’t easily ignite, and is a popular choice for creating prototypes because of its flexibility and durability.
However, it does tend to stick to the edge of the cutting tool, which can degrade the tool’s ability and longevity. This needs to be taken into account when cutting, as tool material and tool coating can both factor into remedying this issue. You should also be sure you’re clearing chips constantly, as failing to do so can result in the cutter breaking.
Proper lubrication will help keep chips from sticking to the cutting edges. Using a mister to provide air blast and coolant mist is effective, easy, and inexpensive. You also want to ensure the tool’s core strength is sufficient to withstand the cutting forces without breaking.
It should be noted that aluminum and other metals have a much smaller sweet spot for optimal feeds and speeds than wood or plastic. When using a CNC router to machine aluminum, you’ll also want to use cutters specifically made for aluminum and/or cutters with a small diameter, as this will help bump your RPM.
Brass is a metal alloy made of copper and zinc and is one of the most highly used materials in the world. Different brass grades have unique properties that make them suitable for various applications. It is also one of the most accessible materials to machines, especially in comparison to aluminum. Where aluminum often sticks to the tool, brass wants to get out of the way.
Yet, U.S. machine shops must utilize brass’s machinability by up to 85 percent. Brass CNC machining is highly efficient due to its low melting point and flow characteristics, making it easy to cast and machine. Machining brass is often used in electrical work, medical, plumbing, and more, but there is room for growth.
Brass is inexpensive and durable, resistant to corrosion, and can withstand extreme temperatures. Brass machined parts are known for their low friction, excellent electrical conductivity, and aesthetic appeal. It cuts much more easily with faster speeds and feeds without negatively impacting tool wear, surface finishes, and chip formation.
It is also entirely recyclable, minimizing waste and ensuring you’re making the most of the materials in your shop. Brass is commonly used in musical instruments and in the manufacturing of electrical components due to its high conductivity, making CNC-machined brass an ideal choice for these applications.
