The Use of CNC Machining for Peripheral and Face Milling

When it comes to machining, there are many types of operations that can be utilized across manufacturing industries. Milling in particular is a highly versatile operation applied on CNC machining operation floors in the majority of fabrication facilities.

 

The precision, flexibility, speed, and quality that CNC milling provides is vital to the operations of the MultiSource Manufacturing LLC network. As a contract manufacturer, we are dedicated to providing comprehensive fabrication and assembly services from start to finish of any project, including complete CNC machining capabilities, engineering and design, a Class 1000 clean room workspace, plastic fabrication capabilities, finishing services, and much more.

 

Within each type of CNC machining operation, there are even more specialized techniques that can be applied depending on the format, materials, and desired end result. Milling, for example, has two primary techniques applied to the majority of situations when milling is appropriate. These two primary techniques are face milling and peripheral milling.

 

Face Milling

This milling operation works with the cutting mill positioned to be perpendicular against the component that will be worked on. The cutting mill spins on a central axis and moves to cut away sections of the component with its perpendicular motion. Face milling is considered to be the most common format for CNC operations. It is highly effective for rapid heavy-duty milling, high-feed milling, and other general face milling processes. Mills will typically use cutters at a 45º angle, but square shoulder and round insert cutters or side and face mills are utilized in other specific applications. 90º cutters are also useful for machining thin-walled components or components with weak fixtures.

 

Peripheral Milling

In contrast to face milling, peripheral milling places the cutting mill parallel to the component that will be machined. The cutting mill spins on an axis parallel to the component as it cuts away material from the work surface. When the mill is positioned this way, the full sides of the cutting mill are being applied to the work surface. This makes peripheral milling much more effective for rapidly removing large amounts of material from the work surface. Because of this, peripheral milling is useful for fabricating a basic component shape quickly, readying it for finer operations. It’s also used in large-scale milling or milling harder materials.

 

For visual reference, this diagram of peripheral and face milling shows a basic format for both CNC operations. Both face milling and peripheral milling are critical CNC machining operations used daily throughout operations in the MultiSource network. Our fully outfitted fabrication facilities have complete CNC machining capabilities in addition to our comprehensive design/build services.

Back to the Basics: Subtractive CNC Machining Operations

Machining operations of various types have been used in industrial settings for over 200 years. In the past 30 years, machining operations have developed exponentially to be faster, more precise, and capable of handling a wider range of materials. With the creation of digital technology and software systems, machining across industries is automated with computer numerical control (CNC). CNC machining is a highly accurate method of altering materials and fabricating even the most complicated parts. MultiSource Manufacturing LLC provides a wide range of services as a contract manufacturer, and CNC machining is a specialty across our six facilities.

 

The MultiSource network has been in operation for over 20 years, and our CNC machining capabilities have developed alongside computer technology, wireless network communications, and equipment improvements. Because of our experience and comprehensively outfitted machining production line, we can provide complete CNC machining services on multiple axes with quick, precision-based operations based on intelligent engineering designs.

 

Our facilities are outfitted with 140 CNC machines that all customers partnering with the MultiSource network can benefit from. Our CNC machining capabilities include 3-axis and 5-axis indexed milling centers as well as 80 mills, 20 Swiss machining centers, and 40 lathes all with vertical, horizontal, or multi-axis movement.

 

With a comprehensive repertoire of CNC machines, basic subtractive machining operations are all in our tool box for infinite combinations in manufacturing virtually any part. Basic, universal machining operations include:

 

  • Cutting: Cutting tools utilize one or more cutting edges that are harder than the component material. Single point tools and multi-cutting-edge tools are two standard cutting tool styles. Both perform more specific types of cutting operations. For example, single point tools perform planing, boring, and turning, while multi-cutting-edge tools perform drilling and milling.

 

  • Drilling: CNC drilling machines manufacture circular holes with two to four helical cutting edges. The drill operates parallel to its rotational axis as it is applied to the component.

 

  • Turning: A turning machine subtracts material from a component surface. A component is held on an axis and turned as a cutting edge removes material in a computer controlled pattern with precision and speed.

 

  • Reaming: Reaming machines are a valuable addition to any precision-based operation floor. Reaming serves to remove miniscule amounts of material from a drilled hole to create a specific size cut.

 

  • Boring: Boring is also used to finish roughly made holes with a bent single tip. The tip is advanced spinning into the pre-made hole and the cut is fine tuned. Boring is highly useful in precision machining and finishing operations.

 

  • Milling: Milling is applicable to the fabrication of many components. A mill with multiple cutting edges is slowly applied to a component surface and that component rotates on an axis. Both peripheral and face milling (cutting parallel versus perpendicular) are utilized on MultiSource operations floors.

Laser Marking and Welding across Industries

Since its earliest beginnings as a theory developed by Albert Einstein in 1917 to its development into a tool commonly used today, the laser has revolutionized operations across industries. The capabilities of laser technology are key to many aspects of medical treatments, scientific research, fabrication, and more. MultiSource Manufacturing LLC utilizes laser marking and welding as a value-added service that offers noninvasive finishing treatments of a wide range of components and full assemblies. As a contract manufacturer with six locations making up the MultiSource network, we are able to offer comprehensive services, including laser marking and welding machines operated by skilled technicians.

For many manufacturing purposes, laser marking and welding is critical to completing components and assemblies. Thanks to our multiple facilities, the MultiSource network is able to offer these high-quality services with the capabilities of a large-scale industry leader and the customer-focused care of a small company. Our laser marking and welding technicians apply their skills across industries, including medical, aerospace and defense, electrical, semiconductor, and more.

 

Components of a Laser Marking or Welding System

A laser marking or welding system utilizes four basic components that work together to conduct the laser’s light-generated-heat to vaporize and remove materials from a component’s surface.

  1. Laser: The laser (light amplification by stimulated emission of radiation) is a highly concentrated light source that, when used in a laser marking and welding application, is actively converting that light energy into heat. This heat can vaporize materials in thin layers from a surface in either vector or raster patterns.
  2. Controller: In a laser marking and welding machine, the controller is the hand that guides the laser. This control is programmed to determine the direction, speed of motion, intensity, and spread of the laser. Most of these machines work on x and y axes on a flat surface, but others can work on a cylindrical surface using a helix adjustment. Other machines use galvo mirrors to direct the laser beam while both the laser and surface remain stationary.
  3. Surface: The surface of the component or assembly that will be marked or welded make up the third part of the laser system. A wide range of materials can be used with a laser system, including all the metals and plastics the MultiSource network works with.
  4. Ventilation: Because a laser system vaporizes the surface material, toxic fumes are created in the process. This emission requires a specialized vacuum ventilation system that can safely remove fumes from the workspace as well as remove debris from the marking or welding process that would otherwise contaminate the operation.

While lasers are commonly used to mark serial numbers, part details, logos, and other information, they have a full and varied range of uses. MultiSource uses laser systems to provide comprehensive finishing, noninvasive assembly, improved precision, and overall increased quality.

How We Maintain and Improve Quality Control for All Our Precision Made Parts

The industrial world today demands some of the most exacting components than it ever has before. From semiconductor microchips to military-grade aerospace parts, the advanced function that so many machines fill in our modern world all require each of their components to fit the highest standards of quality and precision. At MultiSource Manufacturing LLC, our network of multiple facilities adheres to a rigorously tested and continually improved system of quality control for all our services.

 

From precision CNC machining to plastic fabrication and more, the MultiSource network structures our contract manufacturing services on a tried and true system of quality control. The international quality standards of each industry we serve make up the foundational bulk of our quality control system while our own standards refine and improve beyond those outlined industry principles to create a start-to-finish comprehensive approach.

From the Bottom Up

With the core, foundational requirements of the global industrial quality standards in addition to our own values and goals as a contract manufacturer, the MultiSource quality control system is one that offers a quality assurance program from the bottom up. This manifests in two ways. One, with a beginning-to-end manufacturing process, and two, with a wide-to-narrow application of quality control principles.

 

  1. Beginning-to-end manufacturing: Looking at MultiSource quality control standards in terms of the manufacturing process itself, we can see that it literally starts from the bottom up. Each step of the way, beginning with design, engineering, and prototyping and ending with machining, finishing, and packaging, requires the alertness of quality control managers for the application of industry and in-house standards for quality. Because each linear step of the manufacturing process for any component has the potential to create a deviation from quality, our team is diligent in maintaining control throughout. To help us meet our quality control goals in a practical way we utilize several tools at various stages in production, including predictive prototype software, computer controlled machining, CMMs, and other vision systems.
  2. Wide-to-narrow application: To examine our quality control system with the idea that it takes on a wide or broad definition to a much more specified application is to compare and combine the industry standards with our own. For the most part, this means we implement and meet the standards outlined by the ISO and other internationally recognized groups that inspect and certify facilities and processes. Using these standards as a broader foundation, we then apply our own MultiSource in-house standards to sharpen and narrow quality control to guide each step of the manufacturing process.

 

No matter how we view the “bottom up” philosophy of our quality control, the MultiSource network strives to maintain excellence in products and services as a contract manufacturer.

Vertical vs. Horizontal CNC Milling When Fabricating Quality Components

Manufacturing in a broad range of industries utilizes milling as a versatile fabrication method. Machining mills of varying technological advancement have been in use for metals, woods, plastics, and many other materials for over 100 years. Since the 1960s, the development of CNC technology has expanded to the majority of machining operations, including milling. Milling allows for a wide spectrum of capabilities when it comes to the parts and components that can be fabricated, and MultiSource Manufacturing LLC utilizes horizontal, vertical, and multi-axis machining centers to create parts with even the most intricate designs. The network of MultiSource locations offers comprehensive CNC milling services so our customers can get the full benefits of multi-directional machining technologies.

While we provide up to 5-axis machining, MultiSource facilities have multiple vertical and horizontal CNC mills. All of our mills are on a strict preventative maintenance schedule, and despite their limitations in comparison with 5-axis machines, the capabilities of our vertical and horizontal CNC milling equipment never compromises quality in the components we manufacture.

The differences between a vertical mill versus a horizontal mill lie in their capabilities and the parts they are suited to machine.

 

Vertical Mills

The cutting spindle of a vertical CNC milling machine is placed vertically, or perpendicular to the material that will be machined. The mill height can be adjusted and the spindle itself moves horizontally. Vertical mills are typically less expensive than horizontal mills and perform simpler tasks. Vertical turret mills offer versatile milling of smaller projects as the movement of the bed rather than the spindle offers a greater range of motion. Vertical bed mills allow our technicians to work on heavy, large components with adjustable depth and movement.

 

Horizontal Mills

Instead of the cutting spindle vertical mills utilize, horizontal mills use circular cutting heads on horizontal arbors to machine components. Because of the structure of horizontal mills, they are able to use multiple cutters at different angles. This means they can provide complex, multi-sided machining of the material. Additionally, the mill can move in a wider range across the bed, allowing longer and heavier parts to be machined in one operation.

Overall, horizontal mills are more applicable to complex machining operations on a larger scale, but vertical mills have their place in machining single-side components, such as die sinking or metal plates. The MultiSource network offers vertical, horizontal, and multiple axis CNC milling with added benefits of high-speed machining, thru spindle coolant, 40,000 rpm, Renishaw probing, 84” x 33” travel, and much more.

The Importance of Wet Processing in the Manufacturing of Semiconductor Components

When it comes to semiconductor manufacturing, the fabrication process is a highly exacting and intricate one. Semiconductors require a contaminant-free space for the majority of production stages, exceptionally pure materials, and a well-engineered process. From start to finish, MultiSource Manufacturing, LLC provides comprehensive, high-quality fabrication of semiconductor components and assemblies using concurrent engineering processes, a class 1000 clean room, PFA fabrication, and much more.

Semiconductor components are highly present in today’s electronics-saturated world in the tools and devices we each use every day. From the cell phones so present in the routine of our lives to the complex computational and mechanical systems used at NASA and in the military, semiconductors have a vital role. The MultiSource network provides semiconductor components and assembly production including microchip reticle handling and purging, wafer and device handling system components, and wet processing for the primary production stages.

Wet processing is a critical stage in the manufacturing of all semiconductor components. It is during this process in which the format of the pure wafer is created. The wet processing steps are applied in the following way:

1. A resistant material is deposited into the surface of the semiconductor wafer following the engineered format desired of the final product. For the majority of semiconductors, that format is what visually creates a small roadmap of connected nodes.
2. The wafer is then submerged in or otherwise exposed to a liquid or vapor that will etch away the exposed wafer and leave behind the format of the deposited material.
3. Finally, the wafer is cleaned and inspected for quality before moving to the next stage of the manufacturing process.

While the wet processing stages of semiconductor component manufacturing is a small portion of fabrication as a whole, it’s a critical one. The wet etching and cleaning of a semiconductor wafer remains the most effective way of creating an exactly engineered format. This is also why it’s key that our team of highly-trained experts applies reverse engineering to this process as a whole. The format of a semiconductor is what makes it a functioning electronic component, and to create the correct format, our engineers must understand the desired result and work backwards to develop a solution.

With a well-versed team of engineers ready to come into the design process with the understanding of reversed development, well-made semiconductor wafers, a high-class clean room, and reliable fabrication technology, MultiSource is a trusted manufacturer of semiconductor components for OEMs and other customers. To learn more about our work with semiconductor parts and other services, request more information, or request a quote online today.

Importance of Clean Room Standards for Manufacturing and Assembly of Semiconductor Components

Certain areas of the manufacturing operations we provide in the MultiSource Manufacturing network have very specific requirements for a controlled, contained environment during the production process. Specifically, our manufacturing of high-quality precision-based semiconductor components demands a clean room meeting exact ISO standards as well as our own self-imposed standards. The MultiSource network utilizes an ISO Class 3 clean room to eliminate the potential for contamination in every stage of the production process for semiconductor components and full assemblies.

With the protection our clean room provides, MultiSource is able to offer PFA fabrication and welding, in-house electric capabilities, and reverse engineering for even the most complex semiconductor projects.

Our Clean Room

All of our locations have access to our Burnsville facility’s clean room. This clean room meets ISO level 3 classification and Class 1 Federal Standard 209E for eliminating biocontamination and other forms of particulate contamination in the production process.

ISO 3/ Class 1 clean rooms limit the presence of contaminating particles down to:

● 1,000 per cubic meter of particles sized at 0.1 micrometers
● 237 per cubic meter of particles sized at 0.2 micrometers
● 102 per cubic meter of particles sized at 0.3 micrometers
● 35 per cubic meter of particles sized at 0.5 micrometers
● 8 per cubic meter of particles sized at 1.0 micrometers
● 0 per cubic meter of particles sized at 5.0 micrometer

This filtration of microorganisms and particles is critical for the successful production of semiconductor components and assemblies because of the nature of the materials utilized in their manufacturing. Semiconductor assemblies are derived from glassy, crystalline materials such as silicon that have an electrical conductivity decreasing in resistance as temperature increases. Because of this and other properties of semiconductor materials, they are utilized to build electrical assemblies with unique allowance for amplification and energy conversion. However, the process of building semiconductor designed for integrated circuits used in most electronic assemblies requires a highly clean environment, not only during the semiconductor seed material refinement to produce chips with complete clarity, but also during all following production and assembly of semiconductor and electronic components.

Even the smallest particle present in the manufacturing environment can, at the least, alter the quality of a semiconductor assembly and, at the most, completely damage the function of a component and the system as a whole.

With access to an in-house, high-level clean room, MultiSource engineers and technicians are able to consistently produce high-quality, precision-based semiconductor components and assemblies for OEMS and other customers.
