area of the worktable is essential to expand machining capabilities. This not only

allows handling larger workpieces but also facilitates machining more complex
parts, enabling the CNC machine to be used for a wider range of industrial
applications. Upgrade designs may include changing the worktable frame or
using lightweight yet sturdy materials to optimize the area without significantly
increasing the weight.
 Increase Spindle power:
Currently, the spindle in the system has a relatively low power, which
limits the ability to machine harder materials and reduces machining speed.
Replacing the spindle with a higher-power one will significantly improve
machining performance and reduce machining time, making the process
smoother and more efficient. This would be particularly beneficial when
machining harder materials like aluminum or alloys, allowing the machine to
operate stably over long periods without encountering issues like overload or
breakdown.
 Design a dust extraction system:
During machining, dust generation is inevitable, especially when working
with materials like acrylic or mica. Dust not only obstructs visibility during
machining but can also clog mechanical components like lead screws and
contaminate electronic parts, causing damage or short circuits. Therefore,
incorporating a dust extraction system is crucial for improving machining
efficiency and prolonging the life of the machine. This system could be designed
to extract dust directly from the machining area and filter it before releasing it,
keeping the workspace clean and protecting the equipment.
 Design additional Home sensors for the system:
Using Home sensors is a necessary upgrade to optimize the calibration
process and determine the initial position of the axes accurately. The Home
sensors will help pinpoint the exact home position of the axes, ensuring precision
throughout the machining process. This is particularly important for CNC
machines with smaller sizes, where correct initial positioning helps minimize
errors and machining faults. Home sensors also enhance automation and reduce
human error during operation.
