To find out which tooling is best for your job, try using the Taylor tool life equation. This can be written as V(T)to the Nth power=C Where V is the cutting speed in meters per minute, T is the tool life in minutes, C is the cutting speed for a tool life of one minute and N is the Taylor exponent. This formula is used by businesses around the world to calculate which tool and tooling material best meets their needs. It is also a quick way to rule out materials that are not suitable for your purposes.

One of the primary benefits of die casting is its ability to produce parts faster than CNC machining, making it highly economical for large batches. The initial setup for die casting can be costly due to the need for creating molds, but once in place, the per-unit production cost decreases substantially, which is ideal for mass production.

CNC machining also offers remarkable flexibility in terms of production changes. Adjustments to the design can be made quickly, allowing for rapid prototyping and iterative testing without significant cost penalties.

Understanding which tools to use is an important part of any business that machines titanium. If you buy tooling made from the wrong material it could wear too quickly, which means more wasted changover time and a higher overall tool cost. The challenge is to find the right tooling for the right price. To do this, you must first understand the materials most commonly used in tool making. The majority of tooling breaks down into four categories, which are high-speed steels (HSS), cast alloys, carbides and ceramics.

Die casting, however, shines in high-volume production settings. Once the molds are designed and created, die casting enables the rapid production of thousands or even millions of parts with consistent quality and lower labor costs per unit. The efficiency of die casting increases with the number of units produced, making it economically advantageous for mass production scenarios.

CNC machining is highly effective for low to medium production volumes, where the emphasis is on precision and customization. It allows for flexibility in production scaling, making it easier to adjust quantities based on demand without significant additional cost.

Ceramics are chemically inert, which makes them perfect for machining highly reactive metals. Ceramics are also very heat resistant and hard, which means they can be used at high speeds. The only problem with ceramics is their fragility. Ceramics are vulnerable to thermal and mechanical shock, and many experts considered them unpredictable under unfavourable conditions.

Die casting, while capable of producing high-quality parts, may have slightly looser tolerances compared to CNC machining. The casting process involves molds, which can introduce minor variations in dimensions due to mold wear and thermal expansion. However, advances in mold design and process control have significantly improved the precision of die-cast parts in recent years, allowing for tighter tolerances than ever before.

CNC machining offers exceptional precision, allowing for tight tolerances and intricate geometries. The computer-controlled nature of CNC machining ensures consistency and accuracy across multiple part iterations, making it ideal for applications where precision is non-negotiable, such as aerospace or medical devices. CNC machines can achieve tolerances as tight as a few thousandths of an inch, ensuring that parts meet exact specifications with minimal deviation.

Die casting involves forcing molten aluminum into a mold under high pressure. This manufacturing process is highly efficient for producing large quantities of complex shapes with a good surface finish and dimensional consistency. Die-cast aluminum is typically used when the production volume is high, and the part design stays mostly the same.

HSS got its name because it was designed to cut at very high speeds. It is the most highly alloyed tool steel and usually contains tungsten, chromium and vanadium, but this can vary by supplier. High-speed steel tools can be used to machine titanium but they wear quickly and any shop working with high throughput will lose money on the changover costs.

Aluminum alloys commonly used in CNC machining, such as 6061, 7075, and 2024, are chosen for their machinability, strength, and corrosion resistance. These materials are ideal for applications requiring high durability and precise dimensions.

It is less flexible in terms of rapid prototyping compared to CNC machining, but it offers significant production speed and cost advantages when manufacturing standardized products. The die-casting process also allows for integrating features such as bosses and threads, which can be cast directly into the mold.

Additionally, die casting allows for the production of complex shapes with thin walls and intricate details, which might be challenging or more expensive to achieve with CNC machining. This capability makes die casting a suitable method for manufacturing durable and aesthetic components, mainly where the internal geometry of a part is complex.

Moreover, the strength and durability of machined aluminum are often superior because the machining process does not introduce internal stresses or air pockets that can occur in die casting. This leads to more vital parts and better fatigue resistance, crucial for high-stress or wear components.

Now, let’s delve deeper into this comparison and explore how each process can be tailored to meet various manufacturing demands, ensuring you make the most informed decision for your next project.

In contrast, die casting produces parts with a consistent surface finish and excellent dimensional accuracy. While the surface finish may not be as customizable as CNC machining, die casting can achieve smooth surfaces with minimal porosity, which is suitable for various applications. Post-processing techniques such as polishing, coating, or painting can further enhance the aesthetics of die-cast aluminum parts, offering additional flexibility in design.

Another advantage of cast aluminum is the excellent surface finish. The high pressure used in the die-casting process ensures that the molten aluminum fills the mold, reducing surface imperfections and providing a smooth finish that may require less post-processing.

Cast cobalt alloys combine cobalt, chromium and tungsten to provide a tool with good wear resistance. Unfortunately, they have lacklustre hardness at around 60 Rc. This is simply not hard enough for machining titanium but it can still be used for some softer metals.

This is the most common material used when machining titanium. It is incredibly hard over a wide range of temperatures, has high thermal conductivity and has a high modulus of elasticity. Carbide tooling can usually be broken down into two groups. These are tungsten carbide and titanium carbide. Carbide tools come in a wide range of grades and are often used when machining titanium. Most carbide tools will be coated to help improve tool life and disperse heat. Carbide is the preferred tooling material for SGS end mills. We use it in conjunction with specialist coatings to provide the best quality tooling.

On the other hand, die casting is less flexible regarding design modifications once the molds have been created. However, it allows for including complex features such as undercuts, recesses, and intricate contours directly into the cast parts.

This will give you an approximation of your tool life, which can help you to find the best tooling for your job. For most titanium machining the tooling of choice is coated carbide as this combines long tool life with quality results.

Choosing between CNC machining and die-casting aluminum depends heavily on your project’s requirements. CNC machining offers unmatched precision and flexibility, while die casting is renowned for its cost-effectiveness and speed in high-volume production. Understanding these differences is essential for selecting the suitable aluminum manufacturing process for your application.

CNC machining is especially valuable for producing bespoke or highly detailed items in small and large volumes. The adaptability of CNC machining makes it an ideal choice for projects requiring intricate designs and stringent dimensional tolerances. This process can handle a variety of aluminum grades, enhancing its versatility across different applications.

In contrast, die casting frequently utilizes alloys like A380 or A383, known for their excellent fluidity, thermal properties, and ability to produce complex shapes with high dimensional accuracy. These alloys are less suited to machining but are perfect for making lightweight, cost-effective components with good surface finish and mechanical properties suitable for various applications.
