Easy to machine and weld (low- to medium-carbon grades)

Cons:

Lower corrosion resistance

Brittle in high-carbon forms

Limited toughness at extreme temperatures

What Is Alloy Steel?

Alloy steel contains other alloying elements like chromium, nickel, molybdenum, vanadium, or manganese in addition to carbon. These elements are added to enhance specific mechanical or chemical properties.

There are two types:

Low-Alloy Steel (less than 5% alloying elements)

High-Alloy Steel (more than 5%)

Common Alloying Elements:

Chromium: Improves hardness and corrosion resistance

Nickel: Enhances toughness and impact strength

Molybdenum: Increases strength at high temperatures

Pros:

Superior strength and durability

Better corrosion and wear resistance

Excellent performance in extreme conditions (heat, pressure, chemicals)

Cons:

May require post-treatment (e.g., heat treatment)

Alloy Steel vs Carbon Steel: Key Differences

Property	Carbon Steel	Alloy Steel
Composition	Mostly iron + carbon	Iron + carbon + alloying elements
Strength	Moderate to high	Typically higher
Hardness	Good (especially high-carbon)	Excellent (with heat treatment)
Corrosion Resistance	Poor	Good to excellent (depending on alloy)
Cost	Lower	Higher
Weldability	Easier (especially low-carbon)	Can be more challenging
Applications	Structural, automotive, tools	Aerospace, pressure vessels, high-stress parts

When to Use Carbon Steel

Choose carbon steel when:

Cost is a critical factor

Corrosion is not a major concern

The part will undergo machining, welding, or forming

The mechanical demands are moderate

Examples: Frames, fasteners, automotive parts, construction beams

When to Use Alloy Steel

Choose alloy steel when:

You need superior mechanical properties

Surface Finishes For CNC Machined Parts

IN3DTEC — Thu, 10 Aug 2023 03:39:47 +0000

Surface Finishes for CNC Machined Parts

The first impression of any CNC machined part lies in its external appearance and visual representation to onlookers. This crucial aspect has led modern industrialists and manufacturers to prioritize the aesthetics and functionality of their products.

To achieve the desired aesthetic appearance, manufacturers turn to surface finishing treatments for their CNC-machined parts. Surface finishing is a comprehensive and effective process that eliminates outer remnants, scars, threads, blurs, and any unaesthetic marks from the surface of the products.

By employing surface finishing techniques, manufacturers can greatly enhance the overall quality and appeal of their CNC-machined parts. The treatments not only remove imperfections but also provide additional benefits such as improved durability, resistance to corrosion, and enhanced performance.

In this article, we aim to provide you with an overview of common surface finishes available for CNC machined parts.

Varieties of CNC Machining Surface Finishes

Some manufacturers need extreme surface finishing, and the rest require very little. Keeping this point in mind, there are three categories of surface finishing for CNC-machined parts. Find out which one is suitable for your expectations and appeals to your customers.

1. As Machined Surface Finishes

Machining finishing is a very affordable option for manufacturers because it does not incur any extra cost due to being done by a CNC machine.

This surface finish is counted in terms of the Ra factor, which is the surface roughness that is defined as the deviation of a machined profile from the ideal surface.

Ra is the foundation of the calculation of surface finish, surface integrity, waviness, and flatness. Some ideal values of Ra are 3.2, 1.6, 1.8, and 0.8 micrometers. The lower the value of Ra, the higher the dimensional accuracy or tolerances.

Machining finishing is the best for those who have a tighter budget. However, it keeps the surface of CNC-machined parts filled with tool marks. In this way, it is not perfect for high-value projects.

2. Chemical Surface Finishes

Coating the surface of CNC-machined parts with another material is termed “chemical finishing. We can say that it is an extra layer of protection against abrasion, corrosion, and external factors.

Chemical finishing offers an aesthetic appeal to the parts because of the addition of their colour, shine, and other similar attributes. Discuss some of its types.

Anodizing

Anodizing is a phenomenon in which the immersion of a part in an electrolyte solution results in the formation of a protective sheath of oxide on the surface. Anodizing sheaths fall into two categories on the basis of applications.

Type I anodizing (up to 25 microns) is perfect for decorative and aesthetic purposes. While Type II anodizing (25 to 150 microns) is great for providing resistance against corrosion and abrasion to the material due to its thick oxide layering.

Alodine Coating

Alodine means a chromate layer, and alodine coating implies the implementation of a chromate thin coating on the CNC machined parts’ surface to boost their capability against corrosion, heat, and adhesion, resulting in an improvement in their longevity and durability. It works very well for aluminum and non-ferrous components.

Black Oxide Coating

Black oxide coating is a surface finishing process in which a black oxide coating is applied to the surface of CNC machined parts throughout for shielding against different contaminants and physical damages.

It improves the capacity to battle corrosion, offers wear resistance, and offers high lubricity. This surface finishing is the best option for steel, copper, and other alloys that form well-bonded bonds with oxygen molecules.

Electroplating Surface Finishes

Electroplating consists of two words: electric and plating. It involves the deposition of a metallic sheath throughout the surface of a part with the help of passing electricity to reach its melting temperature.

Electroplating is a very effective protection for the workpiece and protects the inner components from all kinds of contaminants and corrosive impacts.

3. Mechanical Surface Finishes

Under mechanical finishes, workpiece undergo multiple cycles of stresses and abrasions with corresponding treatments to obtain a smooth surface on the final products. See its types below.

Bead Blasting

Bead blasting involves the bombardment of spherical beads of glass or ceramic on the surface of CNC machined parts to get their textured, matte surface finish, eliminate imperfections, and create their uniform appearance.

Powder Coating

Attempt to layer a waxy powder on the surface of a part to make it durable and receive its versatile performance. Such powder coats are capable of resisting scratches and chips and do not become obsolete over time.

Brushing

It is a kind of surface treatment, rather than surface finishing. It harnesses a metal-wired brush or an abrasive pad to clean the surface and physically throw out all contaminants or particles on the surface of the parts.

Painting

The use of lacquer and polyurethane in their liquid form to apply over the surface of CNC machined parts to protect the surface from exposure to water, contaminants, dirt, and atmospheric irregularities is known as painting.

Painting CNC surface finishing is a great option to improve the lifespan by keeping corrosion and abrasion at bay by covering the whole external body of a part.

In conclusion, surface finishes for CNC machined parts are instrumental in achieving the desired quality, functionality, and aesthetics. By utilizing the appropriate surface finishing techniques, manufacturers can enhance the performance, durability, and overall value of their CNC machined components.

If you need customized parts on an immediate basis or urgent requirements for a prototype to showcase to your customers while in the meeting, CNC machining can make these dreams come true.

Computer Numerically Controlled Machining (CNC) is a cutting-edge technology in the field of subtractive manufacturing processes for the production of precise and customized components from raw materials.

CNC is revolutionary manufacturing technology for many industries, including aerospace, automotive, medical, and consumer electronics, where quality and precision are paramount.

Keeping high accuracy and producing high-quality components makes the CNC machining procedure expensive. It results in an increase in CNC lead times and financial costs.

In this article, we share eight design tips for reducing CNC lead times and costs during its operations in order to make this manufacturing technology cost-effective for your enterprise.

Tip 1: Simplifying Designs to Reduce Complexity

The more intricate your input designs are, the more equipment arrangements and operations they demand.

Instead of customizing complex designs with intricate characteristics or deep cavities, try simple geometries as much as possible with fewer finishing features to alleviate your CNC lead times and operations.

Tip 2: Minimize the Number of Steps

Lowering operation steps would prove beneficial for minimizing CNC machining time. To make this possible, you should adhere to these pointers as

Disintegrate your larger components into smaller ones and finalize the end product through their assembly.
Either machine your parts in a single step or consolidate numerous elements into a single procedure.

Tip 3: Design with Standardized Tools and Materials

There is no difficulty in finding standardized tools since they are readily available in a global market and known for their high performance and long life.

Second, standardized input materials are easy to buy from any shop, and they are convenient to design and machine.

Third, obeying a standardized procedure is very quick and cheap. For example, fabricating standardized threads is easier compared to customized threads.

Employing these design tips for reducing CNC lead times would have many positive effects during CNC operations.

Tip 4: Concern for the Tooling Requirements of Your Design While CNC Machining

Before proceeding to CNC operations, set your list of tooling, as the utilization of fewer tools or minimal tool changes will aid in a decrease in CNC lead times.

Make a production chart by optimizing tooling paths. It is essential since the shorter the tooling path, the less time it takes to form a final product.

Tip 5: Mitigating Tolerances

Tight tolerance limits will prove more time-consuming and costly for your CNC operations because you should do more operations to fix this issue.

It is recommended to you that you stick to lose tolerance limits as much as possible to reduce the number of operations and machining time. This production strategy will not only minimize your hard work in machining but also in CNC lead times.

Tip 6: Design with the Machining Process in Mind

Your first objective is to clarify all concepts of your procedural steps, potential issues, and capabilities before the inception of the CNC operation.

Choose a simple design that is conveniently machined with common CNC tools and equipment since complicated designs or hard-to-reach aspects need extra tooling time and specialized tools.

Plan a sequence of CNC machining operations in advance to reduce confusion during the process, which results in more time consumption.

Tip 7: Select Your Materials Meticulously

Some CNC materials are hard to machine, so it is your responsibility to avoid them by optimizing your material selection in accordance with minimizing the time to machine your components.

It leads to minimal material waste, reducing material handling time, and the number of materials that need to be machined away.

Tip 8: Test, Optimize, Stimulate, and Prototype

Before leading to full-scale production, ensure that you have tested the prototype on simulation software like Finite Element Analysis Programme to evaluate the potential causes, forecast its functioning, and optimize your design. It results in saving your budget and CNC lead times in production via CNC machines.

Key Takeaways

Implementation of the above eight design tips for reducing CNC lead times and even more on the cost of CNC operations.

What are 4-axis and 5-axis CNC Machining?

IN3DTEC — Wed, 08 Mar 2023 11:51:26 +0000

What are 4-axis and 5-axis CNC Machining?

Milling and turning are crucial phenomena in the manufacturing of several mechanical parts for various industries like aerospace engineering, medical sciences, and automobiles.

However, the formation of respective complex geometries of components necessitates a variety of tool movements. It happens because the work piece is usually stationary while the cutting tool rotates and reciprocates to form complex shapes.

Not only do the benefits listed above apply, but the motion of a cutting tool has additional advantages for manufacturers, such as accuracy, precision, and customized structures. It is why, on the basis of an axis, three types of CNC machining.

3-Axis CNC Machining
4-Axis CNC Machining
5-Axis CNC Machining

The article covers all stories about all CNC machining types, why the latter two are more popular than the former, and their differences.

3- Axis CNC Machining

3-Axis CNC machining works on three coordinate systems: X, Y, and Z. It implies that its spindle and cutter move only three axes, not others. It is a good option for limited geometries, not for complex ones.

Limitations of 3-Axis CNC Machining Make it Unpopular

As it sounds, the perfect machine only has three axes, so it does not access hard-to-reach sections of the work piece. Such a severe limitation encourages manufacturers to carry out multiple rotations of a single fixture, which reduces productivity.

Seeing the above failures of 3-axis CNC machining, innovators have innovated its further developments in the form of 4-axis and 5-axis machining.

What about 4-Axis CNC Machining?

4-Axis CNC machining adds more functionality because it has one more additional rotational axis to work on a work piece. It has a spindle and a cutter that travel up and down, side to side, back and forth, and rotary along the X-axis. It brings more facilities, including high accuracy and speeding up the production process.

What exactly is 5-Axis CNC Machining?

5-Axis CNC machining has one more extra edge over its 4-axis counterpart. It provides for working on the work piece in total on five axes: up and down, side to side, forth and back, and rotation on two axes from three: the x-axis, y-axis, and z-axis.

5-Axis CNC is very efficient in performing milling, turning, tapering, and grooving on various parts using a single fixture.

Distinctions Between 4-Axis and 5-Axis CNC Machining

There is no major difference between 4-axis and 5-axis CNC machining, but if we look in-depth, we will find some subtle contrasting factors. Let us explore each one in a concise way.

Contrasting in their Axes

4-axis CNC machining functions on three coordinate systems and rotation on the x-axis. 5-axis CNCs, on the other hand, operate on the x, y, and z axes as well as two additional rotational axes in addition to the three x, y, and z axes.

Versatility

5-axis CNC machining does not function in a localized way unlike to 4-axis one. It rotates along two of the three axes, x, y, and z. This means that 5-axis machining allows you to rotate a cutter in any of the two axes of your choice, whereas 4-axis machining only allows for x-axis cutter rotation.

Benefits of 4-Axis and 5-Axis CNC Machining

4-axis CNC machining is the updated version of 3-axis CNC machining. The former has more precision, accuracy, and efficacy than the latter. And if you prefer 5-axis CNC machining, it provides a more free hand in turning and milling operations.

5-axis CNC machining has added one exceeding advantage for the facilitation of manufacturers. It lets them perform machining operations in any direction and on any side of the work piece without using multiple spindles to rotate its movement.
