Types of CNC Operations

CNC Milling

» Read More

CNC milling is a method of making high-precision shaped items by cutting various materials with computer controls. In other words, CNC milling is a machining process that involves the use of multi-point rotating cutting tools to remove material from a piece of metal or other material. The machines used for CNC milling operations can translate specified programmes of numbers and letters into movement of the spindle in various methods. Some of the common CNC milling operations are cutting shallow, peripheral millings, making flat cavities, producing deep pits, and more.

CNC Drilling

CNC drilling is a type of machining technique that leverages a revolving cutting tool to make round holes in a stationary workpiece. Typically, the holes are drilled to accommodate machine screws or bolts for assembly. However, depending on the component's design, they can also be employed for aesthetic purposes. Furthermore, CNC drilling units are less prone to errors since they are computer-controlled. As a result, manufacturers can achieve excellent batch-to-batch accuracy and consistency.

CNC Turning

CNC turning is a manufacturing method in which material bars are held in a chuck and rotated while a tool is fed to the item to remove material until the desired design is attained. This technique is also known as the subtractive machining process since the desired shape is obtained through the removal of material. The CNC turning process is used for implementing various operations like boring, facing, drilling, grooving, knurling, and parting.

Gantry Milling

Gantry milling is a machining technique that uses a machine with a fixed table and a moving column that can mill large workpieces from all five sides in one setup. The multipurpose Gantry milling machines allow for implementing operations like drilling, milling, turning, grinding, and laser hardening. This does not distinguish a gantry milling machine from a standard milling machine. However, owing to the bed size, gantry milling machines allow for seamless operation of larger, longer, and heavier workpieces. They often machine workpieces that have metre-scale length, width, and ton-scale weight. Such functionality is notably useful for the aerospace/aviation, automotive, and military/defence industries, as large-scale dies/moulds are required in these areas.

What Kind of CNC Machine We Use?

Contemporary multi-axis CNC machines include a plethora of capabilities that enhance their value and functionality. These, on the other hand, are only functional if the machine can move smoothly along its axis. Furthermore, these axes are in charge of ensuring that the feed is shaped accurately. At Zeal 3D, we use 3-Axis, 5-Axis, and 7-Axis CNC machines.

3-Axis CNC Machines

In 3-axis machining, the workpiece remains still while the cutting tool operates along the 3 axes (XYZ Plane) to trim the part. Since 3-axis machining only operates on three axes, it's quite straightforward and allows material to be removed in the back-to-front, up-to-down, and side-to-side directions. It is one of the most popular cutting techniques used by manufacturers for implementing various operations like milling slots, cutting sharp edges, and drilling holes.

5-Axis CNC Machines

The 5-axis machines use a cutting tool that can travel in five directions: X, Y, and Z, as well as A and B, with an additional rotational axis. This technique is ideal when engineers have to manipulate the workpiece from five different sides simultaneously. The best CNC machines available today are 5-axis milling machines, which can produce accurate and sophisticated parts for aerospace items, artificial bones, oil and gas machine parts, titanium pieces, automotive moulds, architectural, medical, and military products.

7-Axis CNC Machines

The 7-axis CNC machines are similar to typical CNC machines, but with the addition of a seventh axis. The 7-axes involved are the top-down, back-front, and right-left, followed by the axes defined by the rotation of the tool head, spinning of the tool, rotation of the part, and movement for clamping, removing, or reclamping the part. Such 7-axis CNC machining centres are capable of performing milling and turning operations, thereby reducing the amount of time spent changing tools and handling workpieces.

CNC machines are capable of developing a wide range of products with varying levels of complexity and size. However, there are certain limitations and constraints on the size of the products you can produce using CNC machines. Basically, the maximum dimensions that a CNC milling machine can produce are determined by the work envelope of the machine. At Zeal3D, we provide the Maximum building up to 1200x500x500mm, i.e., 1200mm (47″) X by 500mm (19″) Y by 500(19″) Z.

How To Optimise a Metal Part for CNC Manufacture?

When it comes to manufacturing a custom CNC machined part, efficiency plays a significant role. Below are some key factors that you need to consider while designing the part to achieve higher efficiency.

  • Cavities
  • Vertical Radii
  • Hole Diameters
  • Hole Depths
  • Minimum Wall Thickness
  • Tread Depths
  • Thread Diameters
  • Minimum Hole Diameters
  • Tolerances
  • Text and Lettering

Key Factors While Choosing a Metal for CNC Machining?

CNC machining is a fully-automated process; still, there are some factors that you need to consider to ensure the process executes smoothly. Some of the key considerations are:

CNC Machining Time

Whether you need to perform CNC milling or CNC turning, the time required to machine the part is important. For example, If you choose a metal that takes less time to process, the overall cost will be lower. Moreover, the turnaround time for the project will also be shorter.

Material Cost

The raw material cost is one of the critical considerations when choosing a metal for CNC machining. If the raw material is cheaper, the project's overall price will be lower.

Machinability

Some metals are easier to machine than others, known as “machinability”. If the metal is easy to machine, it will take less time to machine the part, and the overall cost will be lower.

Strength

The strength of the metal is another critical consideration. If the metal is strong, it will be able to withstand higher loads and stresses. Moreover, it will also be more durable.

Density

The metal density is also an essential consideration as it affects the weight of the part. Therefore, if the density is lower, the weight of the component will be lower, which can be beneficial in some applications.

How Does Metal CNC Machining Work?

The working of CNC machining with metals is relatively straightforward. The CNC machining reads a specific code for instructions on cutting the metal. This code is written in the computer software, known as the CAD or Computer-Aided Design file. The machine then starts working on the metals according to those instructions.

Step 1

The first thing that happens during the CNC (Computer Numerical Control) process is that a small piece of metal called the “blank” is placed into the machine. The blank is then held in place by a “chuck” or a “collet” device.

Step 2

The next process that happens is that the cutting tool (which can be made of various materials such as high-speed steel, carbide, or diamond) is brought close to the blank by the machine. The cutting tool is then moved along the surface of the blank according to the instructions in the CAD file.

» Read More

Step 3

As the cutting tool moves, it removes small pieces of metal from the blank. These small pieces of metal are called “chips”. The chips are collected in a container that is attached to the machine.

Step 4

The final step in CNC machining is known as “finishing”. It is where the machined part is given a smooth surface finish by a process called “deburring”.
