Quality CNC Precision Machining Practices for Custom Manufacturing

Despite the changes in industrialization and global incorporation most of the world sees today, many parts of the manufacturing industry are still quite diversified. Custom manufacturing in particular is comprised of many different companies ranging from home-garages to multi-branch facilities. Because there are so many skilled custom manufacturers, the industry is highly competitive, and companies must continue to improve and update systems, equipment, and technology to hold their place.

 

MultiSource Manufacturing is committed to hold our own in this industry and strives to produce high-quality parts designed and built in-house and deliver excellent customer care at every step in the process of custom manufacturing.

 

Because CNC precision machining is an integral part involved in the process of MultiSource custom manufacturing, it’s critical that the way we perform that operation adheres to tried and true practices.

 

The MultiSource network has six locations across Minnesota and Colorado, each facility follows the same practices for quality CNC precision machining in the production of reliable custom parts.

 

Best MultiSource Machining Practices

 

  1. Invent: To successfully machine a part that precisely fits customer specifications, our engineering team utilizes advanced prototype software and imaging systems to design a cutting pattern. This pattern will provide our CNC machines with the most efficient program to lathe, mill, and machine a part.
  2. Instruct: Our engineering teams will then instruct a CNC machining center to follow the design of the cutting pattern. This involves programming the designated geometry and pattern into CNC software.
  3. Select: Our facilities host a wide range of 140 CNC machines with 3-axis and 5-axis indexed milling. Selecting the appropriate tools for the machining of a part is critical to successful production. Our machinists and engineers have a deep understanding of which mills, lathes, and turning machines will offer the most efficient and reliable cutting depending on the part.
  4. Monitor: Our CNC precision machining centers may be automated but continued human monitoring of the process is an important practice that should never be disregarded. On each MultiSource floor, operations are continuously monitored for worker safety and to prevent production mishap.
  5. Record: When a machining operation is complete, our engineers, technicians, and machinists all take part in thorough recording and analyzing of the data our CNC software provides as well as quality inspection of machined parts.
  6. Communicate: Throughout the full production process our team is also communicating with customers to continue understanding their needs and provide consistent information about part design, production, and assembly.

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.

Work with MultiSource to Reduce Cost & Lead Time with Best Practice Design

Design Tip #1 – Key Features & Tolerances – Watch the Corners!

Reducing time to market in new product development is a top priority for all our customers.  Working together to make best practice decisions on key feature tolerances in the prototype phase will enhance manufacturability and dramatically reduce machining time and cost.

Common issues that drive cost in machining include sharp corners and/or small inside corner radii.

Why is this problematic?  A tight, small corner radius (e.g. 0.005) will require EDM machining rather than conventional CNC milling.  Providing a larger inside radius (0.032+), when applicable, allows a continuous mill path which significantly reduces cycle time.

Square corners also add additional process steps and machining operations, driving cost and lead time.

For inside corners, plan to use radii 10% or larger than depth of cut, (i.e., .060” radii should not machine deeper than .600” etc.)   Providing this tolerance “relief” in a design will allow a machining partner to use multiple available milling work cells and speed machining operations through the shop.
