What Are the Steps in the Custom Precision Machining
Most precision machining companies work through a series of similar steps for various types of parts.
Design the Graphical Model
A graphical model is required to create any part. This is accomplished with the help of Computer-Aided Design (CAD) software. The CAD software enables the designer to create 2D and 3D models of any part for manufacturing. It is common for designs to start as hand-drawn sketches to understand the basic concepts of the part. The Computer-Aided Design (CAD) designer then refers to these sketches to create the graphical model with accuracy in dimensions. For Computer-Aided Design, there are many popular software programs, both free and paid. Manufacturers can also outsource the design process for any complex design development.
Convert CAD to CAM
Computer-Aided Design creates a graphical representation of the part in a digital format. This representation is easy for the designers, operators, and manufacturers to understand. However, CNC machines used to create the part do not understand this digital format directly. The machine understands coordinates where it can move the cutting tool or shift the workpiece. Therefore, CNC machines require the part design to be in a suitable format that provides the necessary manufacturing instructions. Computer Aided Manufacturing (CAM) software is used to create the readable format for CNC machining. The CAM software takes the CAD model and converts it into CAM format that the CNC machines can understand. Computer Aided Manufacturing (CAM) software uses two types of codes – the G and M codes. The G code controls the coordinates of the cutting tool. The M code controls the auxiliary functions of the machine, such as turning the coolant flow on or off.
Machine Setup
Once the designs are ready in CAM format, it is time to do the machine setup. This will typically require machine tool calibration and mounting of the workpiece on the machine. The machine tools can vary based on the workpiece material and design of the final part. There are various precision machining tools available for different purposes. In this step, it is important to tighten all the clamps correctly and ensure the machine parameters, such as the coolant levels, are acceptable.
Execute the Machining
Once the setup is complete, the machine program is ready to execute. Most CNC machines have a display to monitor the program and adjust various parameters. When the program is executed, the CNC machine will begin the precision machining process.
Completion
Once the part is manufactured using the precision machine, it can be removed. Depending on the requirements, the part may be sent for secondary processes such as grinding or polishing. However, in most cases, a finished product created using precision machining does not need any secondary processing.
A variety of materials can be precisely machined using CNC technology and advanced machine tools. The raw material forms the base component, so its properties impact manufacturing methods, quality, lead times, and costs. Common materials used in precision machining include:
Metals
Metals like aluminum, steel, stainless steel, titanium, and nickel alloys are frequently used. Their strength and durability enable tight dimensional tolerances. Metals can be heat-treated to enhance hardness or other properties. However, machining metals requires robust equipment and cutting tools, plus cooling fluids.
Plastics
Plastics and polymers like PVC, acrylic, nylon, and PEEK have desirable electrical and thermal properties. The machine is faster than metals, with easier tooling requirements. Plastics can also be injection molded, so machining adds precision details. But plastics have less strength, especially in smaller sizes.
Glass
Glass offers excellent optical clarity along with chemical, heat, and electrical resistance. Machining processes like milling, drilling, and turning enable precision components like lenses, prisms, and ceramic substrates. Diamond tooling gives the best results, but generating micro-cracks risks component failure.
Ceramics
Technical ceramics made from aluminum oxide, silicon carbide, zirconium oxide, or silicon nitride provide extreme hardness and heat resistance. Their brittleness, however, limits geometries to simplified forms. Diamonds machine ceramics but require non-contact measurement and rigid fixturing.
Composites
Combining two or more base materials composites blends beneficial properties. Examples include carbon fiber reinforced polymers (CFRPs) with high strength-to-weight ratios. However, machining through multiple layers with different tooling needs raises complexity. Some composites involve pre-impregnated fibers cured after Machining.
Natural Materials
Materials like wood, foams, waxes, and rubber can also be precision machined. Softer materials use high spindle speeds with specialized tooling for superior surface finishes. Graphics prototyping, patterns, architectural modeling, and biocompatible parts apply these organic materials.
While metals constitute the bulk of precision machined components, engineers increasingly select plastics, technical ceramics.
Custom Precision Machining Applications
Much of modern manufacturing is dependent on the wide-scale applications and pinpoint accuracy of precision machining. To gain a better understanding of the importance of precision machining, let's take a look at how it impacts the following industries:
Precision machining has been serving as the backbone of aerospace innovation because of the extreme accuracies and tolerances that can be achieved. Where single errors can lead to severe damages, precision is a necessity. Additionally, CNC precision machining processes are responsible for making many of the components this industry depends on.
With the surge in electric vehicles and innovations at the forefront of the automobile industry, precision machining processes are often used to design and develop the exact specifications for a part or component needed before being added to the assembly line. Common examples of machined parts include engine blocks, wheels, water pumps, and transmissions.
From developing the composite skins on the F35 fighter jet, the communication components on an SAT radio, to prototyping and creating ammunition, precision machining has never been as prevalent as with military and defense. With different nations using different military and defense schematics, the depth of parts and accuracy required is immense and are ripe for CNC machining.
The medical industry relies on innovations in medical equipment and technology to make advancements that improve our health and way of life. Without precision machining, many of the parts in the medical field wouldn't be available. Common examples include MRI machines, surgical tools, implants, orthotic devices, safe enclosures and research equipment.
Precision machining encompasses a variety of techniques, each suited to specific tasks:

VMCs have a vertically oriented spindle that moves along the Z-axis. They are commonly used for milling operations, offering high precision and flexibility in creating complex geometries and features on the workpiece.
HMC (Horizontal Machining Centers)
HMCs feature a horizontally oriented spindle and are ideal for heavy-duty cutting and large-scale production. They provide excellent chip evacuation and are highly efficient for machining parts with deep cavities and complex contours.
Lathes
Used for turning operations, lathes rotate the workpiece while a stationary cutting tool removes material. They are essential for creating cylindrical parts with high precision.
Grinding machines
Utilize abrasive wheels to achieve fine surface finishes and tight tolerances. They are often used for finishing operations to enhance the surface quality of machined parts.
