To meet the demands of material processing, the 5-axis CNC machine has been introduced, which operates in five different directions - X, Y, Z, as well as A and B - automatically, eliminating the need for manual repositioning of the workpiece between operations. It is a precisely created complex machine that finds its applications in industries such as oil and gas, medical, and aerospace.
This blog focuses on the benefits of using a 5-axis CNC machine in material processing. It highlights how this complex machine not only saves time but also offers lucrative features. So, let's explore how the 5-axis CNC machine boosts efficiency in material processing.
How is 5-Axis Cnc Machine Different from 3-Axis Milling
If you are already familiar with the intrinsic features of a 5-axis machine, you will be aware of its unique ability to rotate the tool in five axes simultaneously, unlike the 3-axis milling that operates on three axes only. The 5-axis CNC machine functions smoothly in a single setup, eliminating the need for movement to finish unshaped surfaces. This makes it the ideal solution for milling complex geometries, resulting in reduced cycle times for shaping various materials like steel, polymers, and aluminium.
These two mills, 3-axis and 5-axis, can be compared based on their kinematics or the ways they operate. The "Gantry" setup is a Table setup where the spindle remains static during machining, while a moving part is blended by objects attached to the table. The "Head Table" setup, on the other hand, allows the spindle and table to rotate simultaneously. The "Gated" or Head setup uses a static table mounted on a numerically controlled arm, with the spindle performing the milling.
While there are pros and cons to each setup, the Head and Head Table setups are limited to milling larger objects, with the entire weight carried by the table. Table mills, on the other hand, can effectively chop objects closer to the base, allowing for deeper and more precise grinding. The Head setup has the advantage of faster material removal, but the kinetics thrust poses a challenge, especially with complex and longer CNC cutters. The size and shape of the tool must always be taken into consideration.
How 5-Axis Machining Boosts Efficiency in Material Processing
One technological innovation that offers cost efficiency and effective machining to many industries is the 5-axis machining.We will explore a few ways in which 5-axis machining boosts material processing.
- Ability to Machine Complex Shapes and Contours: The 5-axis cnc machine has made difficult angles and arcs attainable, which other machining types achieved using multiple fixtures. The feature to rotate parts at one single operation makes it possible to accomplish desired geometries, which in turn makes it easy to use the complex shapes and contours.
- Reduced Set-up Time: The reduced set-up time of 5-axis machining makes it possible to get things done on time. The five surfaces working together is a boon to the machining of contoured parts with a single structure.
- Increased Precision: Conventional manual based machine operations require different setups for optimal machining, producing errors and design variability, which further leads the machinist to lose alignment during the process. A 5-axis cnc machine involves a minimal yet effective setups, improving accuracy by eliminating the possibility of error frequency.
- Reduction in Tool Changes: Automated 5-axis machining used by machinists today helps in escaping the rigorous manual repositioning of the workpiece. Using shorter cutting tools and reduction in tool changes helps in increasing the lifespan of the tool ensuring repeatability.
- Reduction in Waste Material: Due to the 5-axis machining centre covering more area of the machine thereby reduction in wastage of materials during the process. This makes the usage of 5-axis cnc machines cost effective and improves the overall performance.
- Faster Cycle Times: A 5-axis machining conducts multiple operations on a single setup reducing the need for multiple setup and change in tools. Resulting increased cycle times and productivity, thereby reducing lead times.
Factors to Consider for Buying 5-axis Machine
Investing in a 5-axis machine requires careful consideration of various factors. While it can significantly reduce floor space requirements, and tooling needs, it's important to choose the right machine that aligns with your business goals. Given are the four important factors that should be considered when choosing the right 5-axis machining for your business.
- Cost: It's important to carefully evaluate the cost justification and leasing options available for this significant investment. Working with specialists who can analyse the specific requirements for 5-axis CNC machining and recommend the most suitable machine for your needs is crucial.
- Size: When purchasing a 5-axis CNC machine, it is essential to consider its size, which depends on the look-ahead function. For a (4 + 1) axes machine, it is recommended to have a minimum of 200 blocks. However, for more complex sequences, a machine with 400 blocks is preferable. For a full five-axis simultaneous sequence, a faster CNC control is required, which may need at least 1000 blocks to ensure high calculation speeds.
- Compatibility with Existing Equipment: Ensure that the cnc machine is compatible with your existing equipment and meets your unique machining requirements. Factors like geometric accuracy, speed, maintenance, and safety should be carefully evaluated to ensure that the machine integrates well into your production process and delivers optimal results.
- Training and Support: The specialists should provide comprehensive training for the use of a 5-axis cnc machine to ensure efficient handling. If any issues arise, the specialists should address them promptly, dedicating necessary resources.
In today's world of fast-paced technologies, time conservation is key to achieving success. A 5-axis CNC machine is a cost-effective method that helps increase productivity while requiring fewer workers. The advantages of this machining system make it a valuable asset for improving the competitiveness and efficiency of the manufacturing industry. In conclusion, the 5-axis CNC machine is a powerful tool that can greatly enhance the effectiveness of production and reduce costs, making it an indispensable part of modern manufacturing.
