6 factors that improve the profitability of high-precision machining

Machine Tool: This is an important factor in machining parts with high precision and consistent quality. Eight percent of today's manufacturers are actually underutilizing their existing machine tools because they lack a scientific approach to optimization.

Tooling: Extending tool life should be a key consideration when choosing a tool. While tool manufacturers continue to strive to improve quality and consistency, the entire manufacturing industry can take advantage of advanced technology to find solutions for tailor-made tools that improve toughness, wear and heat resistance.

Work material: The accuracy that needs to be maintained during machining depends on the work material to be machined. The mechanical and thermal properties of a material play a crucial role in selecting machine tools, tools and determining machining parameters. All of these are considered together to achieve and consistently produce results. For example, while aluminum alloys can be machined and fed at higher speeds, materials such as titanium and nickel-based alloys have lower thermal conductivity and higher chemical affinity with tool materials at higher temperatures. As a result, they can be machined at much lower speeds and require machines with high stiffness, horsepower and torque capabilities. The heat generated during cutting is proportional to the cutting speed and does not dissipate rapidly when processing such materials.

Cutting Fluids: The key opportunity to reduce costs and improve performance lies in better cutting fluids. Many factors influence the correct choice of cutting fluid, and the correct choice of cutting fluid will result in better material removal rate and surface finish. Proper disposal methods are also critical as environmental regulations become more stringent. Even new technologies such as Minor Quantity Lubrication (MQL) need to be considered.

Machining accessories: Effective part technology and workholding design can make the part manufacturing process faster, more accurate, and more profitable. However, this relies on a culture of technical scouting and continuous improvement.

Machining parameters: A major factor is the machining parameters. Speed, depth of cut, and toolpaths are all fundamental considerations for machining high-precision parts, and manufacturers should apply performance-based optimization to continually improve.
