CNC Milling parts-What are they?

Worthy Hardware specializes in accurate precision CNC machining services. Precision computer numerical control (CNC) machining, as the name suggests, uses specialized computer software (e.g., CAD/CAM) and computer-controlled equipment to produce very precise and exact parts and products from a wide range of materials.

While the majority of CNC milling is employed in the metalworking sector, the tools are very versatile and can be used to manufacture cost-effective, precise parts for a variety of industries.

What is CNC Milling Part?

CNC milling parts are parts made using precise computer numerical control (CNC) machining, which uses specialized computer software (e.g., CAD/CAM) and computer-controlled milling equipment to generate highly accurate and exact parts and products out of a range of materials.

CNC milling parts is one of our most popular services, and it’s a catch-all term for numerous subtractive manufacturing processes. Worthy Hardware specializes in accurate precision CNC milling machining services.

Precision CNC milling parts may be manufactured in various metals, ranging from aluminum material, stainless steel material, brass material, and steel material to exotic and expensive metals such as gold, iridium, and platinum. Our CNC machining experts can pick the proper mill and optimize manufacturing paths to achieve tight tolerances.

CNC Milling Workflow Procedures

Step 1: Prepare a 2D/3D CAD Model

Create a machinable 2D/3D design for manufacturability (DFM) of the final product using CAD/CAM software such as Autodesk Inventor or SolidWorks. The program you choose determines how to prepare a CAD file for CNC machining. On the other hand, some applications can transform 2D photos into 3D CAD files.

The operator is also handed a technical sketch design for manufacturability with information such as:

A part’s critical features/dimensions
Tolerances
Thread Identification
Preferences for finishing
Lines of construction

Step 2: Save Your Design in a CNC-Compatible File Format.

The CNC milling will not comprehend your design unless it is in a CNC machining file format. As a result, using the CAD/CAM program, you must convert your CAD model into CNC-compatible file types.

When converted, the file will instruct the mill on the process’s rotational and linear movement, cutting sequence, toolpath, machine, and workpiece speed.

Step 3: Install and Operate a CNC Milling Machine

The cutting tools will be attached to the spindle by the operator, and the workpiece will be placed on the table. They will next configure the mill to start the machining program and milling.

Types for CNC Milling

There are vast varieties of CNC milling for various materials such as metals like aluminum, steel, stainless steel, and more, and plastic materials such as PEEK and more. CNC mill machines can mill details, features, and text into parts like casting and 3D printing. Types of CNC milling include;

3-axis CNC Milling machines

We offer 3-axis milling to manufacture machined parts of various designs, metal parts, plastic parts, and forms. It is developed from rotary filing and is a milling method that operates on two axes, the X and Y axes.

The workpiece stays stationary while the cutting tools travel along the three axes to mill the item in three-axis machining.

Three-axis machining, which may be used for automatic/interactive operation, milling slots, drilling holes, and cutting sharp edges, is still one of the most extensively used processes for creating mechanical parts.

Because Three-axis machining only uses three axes, it is quite simple and enables the material to be removed in these three directions, which are represented by back to front, side to side, and up and down.

While Three-axis machining is a more basic machining method, it may be appropriate for your machining project based on the size of your production run, workpiece requirements, accuracy and surface finish limits, materials utilized, and holding machining capabilities.

4-axis CNC Milling machines

4-axis milling is similar to 3-axis machining in that a cutting tool removes material from a component to obtain the desired shape and profile. Milling is conducted on an extra axis in the case of 4-axis machining.

A 4-axis CNC mill, like a 3-axis machine, works on the X, Y, and Z axes, but it also incorporates rotation around the X-axis, known as the A-axis. Our machining technique now includes a fourth axis. Most of the time, the workpiece will be turned to allow for cutting along the B-axis.

When holes and cut-outs need to be formed in the side of CNC parts or around a cylinder, 4-axis milling comes in handy. They can provide exact outcomes with rapid and efficient labor based on computer numerical inputs.

5-axis CNC Milling machines

All of the axis of 4-axis machining are included in 5-axis machining, along with one extra rotating axis. The greatest CNC milling machine available today is the 5-axis mill, which is capable of producing accurate and sophisticated parts for artificial bones, aerospace items, titanium pieces, oil and gas parts, automotive molds (instead of using injection molding), and medical, architectural, and military products.

On a 5-axis mill tool, the 5th axis revolves around the B-axis, which spins around the Y-axis in the X-Y-Z plane. This multidimensional rotation and tool movement enables B-axis to produce a piece with unprecedented accuracy, quality, and speed.

5-axis machining can manufacture complex parts, which is why it is so vital for high-level applications such as aerospace as opposed to low volume.

However, 5-axis machining is becoming increasingly common because it enables single-step machining (saving lead time), provides greater access to the milled parts’ geometry and enhances tool life and process efficiency by tilting the table for the optimal cutting position.

So, which machining method should you choose for your project? It all boils down to your specific needs, money, and timeframe. Speak with one of our certified precision CNC machining service engineers for expert guidance on finding the best fit for your requirements.

Parts of a CNC milling machine

Headstock

The headstock is an important component of the CNC machining mill that travels along the X-axis. It’s on the left side of the CNC machine. It secures a spindle with a revolving tool holder to aid in the rotation of the cutting tool.

To govern the length of the workpiece while rotating it on the CNC mill bed, the tailstock is linked or detached from the headstock.

The Control Panel

The control panel is mostly made up of a screen and a keyboard. It controls and monitors all motions of CNC mill working components such as the X, Y, Z, and machine tool spindle in real-time.

This enables the provision of user interfaces for controlling the movement of the machine tool throughout the processing process.

The control panel also makes it straightforward to handle the machine tool’s numerous communication modes. G code, for example, is a common CNC programming language that instructs CNC machines on how to accomplish their duties.

Chuck

When the machine tool is turning, the chuck is utilized to secure the workpiece. Using a distinct tapered surface enables the operator to securely clamp round or irregularly shaped items on the CNC machine.

They may be used for outside diameter or interior diameter clamping. Chuck tools are composed of solid materials (mostly cemented carbide) to guarantee that the chuck can grasp the workpiece securely enough to accomplish the cutting while resisting wear throughout the manufacturing process.
