About Project

When people look for a replacement trumpet that gives a different sound, CNC is usually chosen to custom a blow-off valve. With the shape and structure modified, the whistling trumpet could have a higher or lower pitch.

Solution

• Step 1: The CAD model was examined and transformed into a CNC-compatible format with the software AutoCAD.
• Step 2: A most suitable type of CNC machine was chosen according to the complexity of the product design and the cost of the workpiece.
• Step 3: Certain operations were configured and the G-codes were input on the machine. The workpiece was mounted on the machine as well.
• Step 4: The workpiece got shaped and the holes were drilled automatically. It would be inspected during and after the machining process for quality assurance.
