What is CNC Machining

What is CNC Machining

We have come a long way since the days of punched paper tape spools. Today, some mills can perform machining processes on five different axes without removing and repositioning the part in a fixture. This advancement leads to faster and more accurate production. CNC turning, which utilizes your 3D CAD models to create cylindrical parts, is accomplished using a high-speed CNC-controlled lathe. The concept is similar to removing slivers of wood from a spinning maple log (or white ash) to ultimately shape a baseball bat.

How Does CNC Machining Work

CNC machining differs from 3D printing in that it involves subtraction rather than addition. In CNC machining, you start with a solid block or cylinder made of metal or plastic and cut away material to achieve the desired shapes. This process can be likened to a high-speed form of sculpture, where drill-like tools called end mills replace traditional bits and chisels.

During milling, these end mills spin at incredibly high speeds, often reaching tens of thousands of revolutions per minute. The speed can be adjusted to prevent cutting errors or damage to more delicate materials, emphasizing that sometimes a slow and steady approach is best. The primary goal of CNC machining is precision, with tolerances as tight as ±0.001 inches (±0.025 mm).

Types of CNC Machines and Cutting Tools 

The technology behind machining has progressed a lot. For a long time, the basic lineup in every machine shop was CNC lathes with two axes as well as three-axis CNC machining centers. Some were horizontal while others were vertical however, for the vast part, work would bounce between both until all the machining steps were completed. In recent times, thanks to clever machine tool makers the distinction between mill and lathe has become blurred. Multitasking machines are multitasking machines that combine the spindle for milling and a tool changer with a lathe-style head as well as a turret (the part that houses all the equipment). Mill-turn lathes also incorporate stationary and rotating cutting tools, and turning machining centers have become more and more widespread. For instance, we employ lathes that have Live tooling to allow features like radial and axial grooves, holes, flats, and slots.

Machining centers could also include greater than 3 axes. For instance, a 5-axis mill can move across all of its axes simultaneously which is a feature that can be useful to make parts such as impellers as well as a variety of other complicated geometries. In addition, a traditional three-axis machine center could be fitted with an axis that is tilted and/or turns. This capability of 3+2 is great for machining multiple sides of a workpiece with one operation and eliminating the need to re-fixturing which creates more time in production. The exact configuration is what matters, and there are many of them–each type of machine is specifically designed to minimize manufacturing operations and enhance productivity flexibility.

Advantages and Common Applications of CNC Machining

Our CNC machining provides multiple benefits, including:

Precision and reproducibility

strict tolerances

high-quality production materials

Lower cost of piece-parts in larger quantity

strong post-processing capabilities that enhance the appearance of materials and cosmetics

As compared to injection molding CNC manufacturing produces parts with greater speed. Additionally, it provides greater precision in terms of dimensional accuracy than 3D printing (although this could change with new developments) and makes parts with more mechanical characteristics in three dimensions than 3D printing. It is true that CNC commonplace comes at a price increase and is typically associated with lower volumes of parts. It also offers lower flexibility when it comes to complicated geometries in comparison to the 3D printer.

As mentioned before, CNC machining is a preferred manufacturing method to create precise parts, be it for prototypes or production at the end of the line. It is extensively used in the medical, aerospace, and automobile industries due to its capability to produce parts quickly and precisely made of high-quality materials like:

enclosures and housings

brackets

Manufacturing equipment and fixtures

bearings and gears

Internal mechanical components

medical instruments

Applications of CNC-Machined Parts

CNC machining utilizes a variety of cutting tools to manufacture an extensive range of components, from marine and mechanical parts to aerospace components. These applications often require high-precision parts, including shafts, gears, bushings, flywheels, cams, molds, and propellers.

The products produced on CNC machines depend on the specific capabilities of the machine being used. Each type of CNC machine has distinct machining capabilities tailored to the manufacturing of unique components. For example, round or spherical parts that are created in a CNC turning center cannot be produced with a CNC milling machine.

Common Materials Used In CNC Projects

Materials Suitable for CNC Machining

CNC machines can process a wide range of materials, depending on the specific application. Common metals used include aluminum, brass, copper, steel, and titanium. Additionally, non-metallic materials like wood, foam, fiberglass, and plastics (such as polypropylene, ABS, POM, PC, and nylon) are frequently machined. However, some materials are not suitable for CNC machining due to their physical properties; for instance, rubber and silicone are too flexible, while ceramics are too hard to machine with precision.

Stainless Steel

There are a wide variety of alloys of stainless steel on the market today, and CNC machining applications tend to favor popular grades such as 304, 316, 416, and 17-4 PH stainless steels. Stainless steels are strong materials with naturally protective oxide layers which makes them an excellent choice for harsh environments; their grades differ due to different alloying elements used – molybdenum increases corrosion resistance whereas sulfur improves its machinability in certain grades such as 303 stainless steel.

Aluminum

Aluminum is an ideal material choice for CNC machined components due to its superior machinability, lightweight nature, strength, and high corrosion resistance. Aluminum alloys also boast excellent thermal and electrical conductivity properties which makes them suitable for applications in thermal management and electronics. When choosing between stainless steel and aluminum for CNC machining, take both cost considerations as well as your application requirements into account.

Titanium

Titanium alloys have become an indispensable choice for medical equipment and implantable components, including screws and devices. Furthermore, titanium is widely utilized by aerospace, industrial, and military industries due to its superior strength, creep resistance, and excellent metallurgical properties – approximately twice as strong as aluminum but slightly more than half its density; popular in consumer products including lightweight golf clubs.

Copper

Copper is an outstanding conductor of electricity and heat, second only to silver in terms of thermal and electrical conductivity. Unfortunately, pure copper (approximately 99% commercial purity) poses challenges to CNC machines due to its malleability at lower temperatures and considerable ductility; however, several copper alloys exist that offer similar or even better thermal and electrical properties than pure copper.

Brass

Brass, an alloy of copper and zinc, shares many properties with copper. Known for its durability and ease of machining, brass is corrosion-resistant, electrically conductive, and features a low coefficient of friction – qualities that make it suitable for many different uses such as plumbing, electrical work, artistic endeavors, and medical applications.

Applications of CNC-Machined Parts

CNC machining utilizes a variety of cutting tools to manufacture an extensive range of components, from marine and mechanical parts to aerospace components. These applications often require high-precision parts, including shafts, gears, bushings, flywheels, cams, molds, and propellers.

The products produced on CNC machines depend on the specific capabilities of the machine being used. Each type of CNC machine has distinct machining capabilities tailored to the manufacturing of unique components. For example, round or spherical parts that are created in a CNC turning center cannot be produced with a CNC milling machine.

The differences between CNC milling and CNC turning

[litami]

What products can be made on a CNC machine?

Materials Suitable for CNC Machining

A wide array of materials can be processed using CNC machines, contingent upon the specific application. Commonly utilized metals include aluminum, brass, copper, steel, and titanium. Additionally, non-metallic materials such as wood, foam, fiberglass, and plastics (e.g., polypropylene, ABS, POM, PC, and nylon) are frequently machined. However, certain materials are not conducive to CNC machining due to their physical properties. For instance, rubber or silicone is too pliable, and ceramics are excessively hard to machine with precision.

Applications of CNC-machined parts

CNC machining, leveraging a diverse range of cutting tools, facilitates manufacturing a vast spectrum of components, from marine and mechanical parts to aerospace components. These applications often necessitate high-precision parts such as shafts, gears, bushings, flywheels, cams, molds, and propellers.

The types of products produced on CNC machines are influenced by the specific capabilities of the machine used. Each CNC machine variant has distinct machining capabilities that cater to the manufacturing of unique component properties. For example, round or spherical parts fabricated in a CNC turning center cannot be produced using a CNC milling machine.

CNC Turning Parts

In the CNC machining industry, CNC lathes are employed to process straight cylinders, oblique cylinders, and arcs, as well as various threads, grooves, and worms. These machines can also handle complex rotating surfaces, such as hyperboloids. Typical CNC turning parts include shift knobs, pulleys, shafts, hubs, bushings, and flywheels.

CNC Milling Parts

CNC milling machines are predominantly used to process various intricate planes, curved surfaces, and housing parts. Examples of parts commonly machined by CNC milling include cams, molds, connecting rods, blades, propellers, and box- or housing-shaped components.

Limitations of CNC Machining

Despite the versatility of CNC machines, certain parts are unsuitable for CNC machining due to inherent limitations. These limitations include:

Inner Vertical Angles

Given that CNC milling tools are cylindrical, they inevitably leave a radius on vertical angles when cutting inner walls. While the tip radius can be minimized by employing a tool with a smaller diameter, it is impossible to achieve a perfect internal vertical angle regardless of the tool diameter.

Parts with deep cavities

Tools are generally most effective when cutting cavities with depths 2-3 times their diameter. Machining cavities deeper than four times the tool diameter significantly increases the difficulty and risk of tool breakage.

Thin-Walled Parts

Thin walls present a challenge in CNC machining due to their propensity for deformation or breakage. Machining thin walls necessitates multiple passes at low cutting depths, and thin features are susceptible to vibration, complicating the machining process and extending the machining time.

What is deep drawing and how does the process work?

Deep drawing is an essential metal-forming process that transforms flat sheets of metal into intricate three-dimensional shapes. This technique is widely employed to produce a variety of hollow, cylindrical parts, including cups, cans, pots, and automotive components, where the depth exceeds the diameter.

The deep drawing process

consists of several critical steps:

Blanking: A flat sheet of metal, known as a blank, is precisely cut from a larger sheet to achieve the desired size and shape.

Drawing: The blank is positioned over a die with a cavity that corresponds to the desired final shape. A punch forcefully drives the blank into the die cavity, effectively stretching and bending it into the required form.

Redrawing: In many cases, multiple drawing operations are necessary to achieve the specified depth and shape. Redrawing involves passing the partially formed part through a series of dies, further refining its shape.

Trimming: Excess material is systematically trimmed from the formed part to ensure it meets the final specifications and dimensions.

Deep drawing stands out as a versatile and cost-effective manufacturing process capable of producing complex shapes with precise tolerances.

Advantages

The deep drawing process in sheet metal has the following advantages when manufacturing sheet metal parts in large production volumes.

Manufacture hollow cylindrical, rectangular, square, and other complex geometries

Low manufacturing /labor cost.

Less material consumption.

High productivity.

Highly precise parts.

High strength and minimum weight parts.

Low tool construction cost compared to progressive stamping tool

Application

Deep drawing parts can be used in a wide range of industries, including:

Construction: Bending components for construction projects such as roofing and siding

Automotive: Bending sheet metal for use in body parts such as doors, hoods, and fenders

Aerospace: Bending sheet metal for use in the manufacturing of fuselage, doors, and fenders.

Advertising: Bending sheet metal for signage and advertising, including signs and billboards

Food processing: Bending sheet metal for beverages, kitchen equipment

Transportation: Bending sheet metal parts for cars, trains, buses, and aircraft

Art: Bending sheet metal for use in building cladding

Common Problems During the Deep Drawing Process

Deep-drawn sheet metal parts can exhibit several defects if deep-drawing part design guidelines are not followed or if the manufacturing process parameters are not properly set.

The following are common issues:

Wrinkling

Wrinkling defects appear in the vertical wall or flange of deep-drawn sheet metal parts due to high radial and tangential compressive stresses. This issue can be prevented through effective tool and process design. 

Tearing and Thinning  

Tearing and thinning occur in the inner section of the deep-drawn part as a result of high shank holder pressure, which restricts the free movement of the material, leading to elevated tensile stresses in that region. Additionally, tearing may occur due to a small corner radius. 

Surface Defects  

Surface defects, such as scratches and tool or die marks, can arise from a small clearance between the tool and die or inadequate lubrication. 

Earing  

Earing defects cause irregular features on the flange of deep-drawn parts and result from the anisotropic behavior of the material. By addressing these issues, manufacturers can improve the quality of deep-drawn components.

What is Impact Extrusion

Impact Extrusion is a metal processing technology that places a metal blank in a die. Under high-speed impact or pressure, the metal blank undergoes plastic deformation inside the die, ultimately forming the desired product shape.

What is extrusion

Extrusion is a metal-forming process typically used to create linear products with a fixed cross-sectional profile. It is accomplished by forcing metal (or other material) through a die with the desired solid or hollow cross-section.

There are several benefits to extrusion. First, many shapes can be made through extrusion, often with very complex designs. It can also be used on otherwise brittle metals since the stresses involved are only compression and shear. The finished parts also tend to have an excellent surface finish.

While impact extrusion is one method, there are a variety of extrusion options available to manufacturers. These include the standard hot and cold extrusion processes as well as friction extrusion. Another similar process is drawing, the only difference being that the metal is pulled through a die rather than pushed through it.

What is the impact extrusion process?

What distinguishes impact extrusion from other processes is that the workpiece is forced through an aperture at a much higher speed than other methods. The first step in the impact extrusion process is to take a block of metal and place it into a press. The press may be mechanical or hydraulic and can cycle up to 60 times per minute.

The punch then pushes the block into the die at great speed, forcing the block’s metal to reshape around the punch while conforming to the outside of the die. This action controls the final shape of the workpiece, both inside and outside. Lubricants can be added as needed to facilitate this process.

One strike is enough to form the block into its new shape, and then a reverse strike is used to eject the metal from the die. There are three types of impact extrusion operations. A forward strike is where the block is pushed into the die. A reverse strike forces the block around the punch. A combined strike is where the block is pushed into the die and around the punch simultaneously.

It is important to note that the thickness of the workpiece is directly related to the gap between the punch and the die. This means that the thinner the workpiece, the tighter the tolerances. Also, as mentioned earlier, the surface finish of the finished piece will be better than the starting piece. The aluminum’s grain structure is refined during this work-hardening process, strengthening the metal in its new form.

Metal extrusion can be subdivided into the following categories based on the direction of the extrusion flow and the medium through which the force is applied.

Metal extrusion types

Direct extrusion

Indirect extrusion

Hydrostatic extrusion

Transverse or longitudinal extrusion

Impact extrusion

They can also be classified based on the operating temperature

Hot extrusion

Cold extrusion

[litami]

What is Impact Extrusion

Impact extrusion is a highly efficient manufacturing technique used to produce various products.  Which is one of the fastest ways to get to near-net shape for many parts and components. Our process begins with a lubricated metal slug—also called a blank or a puck—that is placed in a die cavity. The metal puck is struck with a punch powered by a mechanical or hydraulic press. This forces the metal to flow into a shape or position almost instantly. In this post, we will cover its working principles, materials used, surface treatments available, advantages, disadvantages, applications, and future trends.

The Basics of Impact Extrusion

Impact Extrusion is a precise and efficient machining process that produces high-quality cylindrical parts by rotating a workpiece against a cutting tool. This technology is crucial in various industries, from automotive to aerospace, due to its ability to create intricate and accurate components.

1. Material Placement

The process begins with a slug or blank of metal, typically a soft, ductile material like aluminum, copper, lead, zinc, or tin. This slug is placed in a die, a tool that shapes the material.

2. Punch Movement

A punch, a solid piece of metal, then strikes the slug at high speed and pressure. The impact force is usually generated by a mechanical or hydraulic press.

3. Metal Flow

Upon impact, the metal flows around the punch and into the die cavity, taking the shape of the die. The metal’s flow is primarily in the radial direction, allowing the material to spread thinly and evenly.

4. Die Action

The die, which is precisely machined to the desired shape of the final product, confines and directs the flow of the metal. Depending on the die design, the process can create various shapes, including cylindrical, conical, or complex profiles.

5. Ejection

After the punch retracts, the newly formed part is ejected from the die. This step may involve additional mechanical systems to ensure the part is removed without damage.

Difference Between 3-axis, 4-axis, and 5-axis Milling

For 3-axis machining, the tool can move in three distinct directions independently or simultaneously relative to the material. It can move in the X, Y, and Z linear directions. In the case of a PROTOTEK 3-axis milling machine, it’s back to front (Y-axis), side to side (X-axis), and up and down (Z-axis).

There are different variations for 4-axis machining, but we will talk about vertical 4-axis milling. 4-axis machining has the same 3 axes (XYZ) as the 3-axis, plus an additional axis for rotation. With a PROTOTEK machine, it’s the A-axis. The A-axis has the workpiece rotate around the X-axis. The rotation allows 4 sides to be machined while the part stays in the fixture and needs only one setup.

Like 4th axis machines, 5th axis machines also have their variations. The machines typically either use a rotation in the A-axis and C-axis or a rotation in the B-axis and C-axis. Both the workpiece and the spindle rotate in 5-axis milling. The two main types of 5-axis machining are simultaneous and 3+2 index milling.
