A Complete Guide of Angle Milling? Its Processes, Advantages, and Applications

Research estimates that the global machining sector was US$1.5 Billion in 2022. China and it will be worth $27.3 billion by 2030. Angle Milling plays a significant role in this growth.so, let’s discuss what ange milling is. It is a process that uses a milling cutter to cut a workpiece at an angle other than 90 °. Straddle milling cuts the workpiece at both ends simultaneously. So, angle milling differs from straddle milling. You can use both single-angle milling and double-angle milling cutters for this purpose. However, a double-angle milling cutter is more expensive and efficient.

A Complete Process of Angle Milling

Now, you are familiar with angular milling. So, let’s explain its complete process in detail.

1. Planning and Preparation

Before starting, you first need to determine the angles at which the surface needs to be machined. So, these angles depend on the design requirements of the metal part. After that, the engineers select the suitable milling cutters. They may include end mills, face mills, or angle cutters. Additionally, different processes like a vise, an angle plate, a rotary table, or a custom fixture can be used to make workpieces of different shapes and sizes.

2. Setting Up the Milling Machine

Here, the next step is to set up the milling machines and cutters in the machine spindle. So, if in case this milling machine has a tilted head. You can adjust it to a desired angle. Besides this, you can also attach the angle plate and workpiece to a desired angle. If you are using a rotatory table, you can adjust the workpiece on the top.

3. Workpiece Setup

The workpiece is attached firmly to the selected work-holding device. It will help provide stability and position the workpiece correctly. Moreover, you can also check for the alignments of the workpiece using precision measuring tools. They may include a dial indicator or a protractor.

4. Machining the Angle

At this stage, engineers set the cutting parameters based on their appropriate speed, feed rates, and depth of cuts. After that, the milling process begins with the lightweight cut to check alignment and overall setup. Then you need to make a few passes to remove the bulk of the material. Now perform the final passes to get the precise angles and surface finish.

5. Quality Control

Once the workpiece finishes, you can measure the machine angles. This can be done using tools, i.e. angle gauge, protractor, or coordinate measuring machine (CMM). This practice will help meet the required specifications. After that, monitor the surface finish to understand the required quality. It is usually carried out using the surface roughness tester if necessary. Moreover, the final step is to verify the other important dimensions

How is Angle Milling Different from Traditional Milling?

Traditional milling is distinct from angular machining. Moreover, traditional milling cuts at a 90-degree angle (perpendicular to the workpiece). So, it utilizes a conventional milling cutter with straight teeth. Furthermore, it cuts straight lines and creates flat surfaces.

Advantages of Angle Milling:

We have discussed both angle and traditional milling. So, let’s understand its advantages.

1. Complex Shapes:Bevel milling creates complicated shapes like chamfers, bevels, v shapes, and taper surfaces.
2. Angular cuts: Angular milling is best for creating angular cuts, dovetails, etc
3. Accurate: Angle milling is highly accurate. So, it is used when more precise cuts are required.
4. Easy Access:It cuts hard-to-reach areas such as corners or small cavities. These areas can not be accessed easily by standard cutters having straight teeth.
5. Custom Designs: Custom designs require unique angular features. So, it is best for creating custom designs and prototypes.

Limitations of Angle Milling:

Angular milling has many advantages. But, it also has some disadvantages. So, these are mentioned below:

1. Time Consuming:Angular milling machines require specific skills and knowledge to set up. Moreover, it also needs accurate alignment. So, it can be costly and time-consuming.
2. Less Adaptable: Angle milling machines are not adaptable. Once an angle is set, it is difficult to change and adjust it. So, you have to reset the entire machine to adjust the angle.
3. Noise: Angular machining can generate vibration. So, it also produces chatter. This decreases the accuracy of the machine. Moreover, it also produces hazardous noise pollution.

Alternatives to Angle Milling:

There are many alternatives to Angular milling. But, it depends on your requirements and desired outcomes.  So, a few of them are mentioned below:

CNC Machining:

Computer Numerical Control machining uses computer-controlled machines. This machine cut the material into complicated geometrical shapes. So, it makes car parts, airplane parts, and medical equipment.

Grinding:

Grinding is another process of shaping your desired material. So, it uses an abrasive wheel to shape the workpiece. Aluminum oxide, silicon carbide, and ceramic are the materials used in grinding wheels.

Traditional Milling:

Traditional milling works on simple shapes. So, it produces straight and perpendicular cuts. It is utilized when oblique cutting is not required.

Applications of Angle Milling:

Angular machining has wide-scope applications. Some of its applications are:

• Automotive Industry:Angle milling produces engine components i.e. transmission parts, and suspension components.
• Medical Industry:It manufactures medical implants, surgical instruments, and prosthetic devices.
• Machinery: Angle milling is used for making components of machines. So, these include gears, shafts, and bearings
• Ship Building:

It is used in the construction of ship materials. Such as propeller shafts and engine components.

• Sports Equipment:

It produces high-quality sports equipment. e.g. golf clubs, and bicycle components.etc
