🛠️ Components

1. Drill Bit (my drill 3.SLDPRT)

• The cutting tool that performs the drilling operation.
• Designed for efficient penetration into material.
• Geometry optimized for torque transmission.

2. Drill Covering (my drill covering 1.SLDPRT)

• Protective casing around the drill.
• Ensures user safety and structural rigidity.
• Prevents debris from interfering with moving parts.

3. Drill Support (my drill support 1.SLDPRT)

• Provides axial and radial support to the rotating drill.
• Reduces vibration and improves accuracy.
• Acts as the interface with the frame/fixture.

4. Rotating Storage (my rotating storage.SLDPRT)

• A rotating holder or chuck that transmits torque from the motor/drive shaft to the drill bit.
• Allows easy attachment and replacement of drill bits.
• Can store rotational kinetic energy for smoother operation.

5. Assemblies

• iris.SLDASM
  Likely represents a subassembly (possibly iris-like mechanism for controlling drill engagement or clamping).
• my assembly drilling 2.SLDASM
  Full assembly combining drill, support, covering, and rotating storage into a functional drilling unit.

⚙️ Working Principle

The drilling mechanism operates in the following sequence:

1. Torque Input

   • A motor or manual drive transmits torque to the rotating storage (chuck-like component).

2. Power Transmission

   • The torque is transferred from the rotating storage to the drill bit.
   • The support structure ensures the drill bit remains aligned and stable.

3. Cutting Operation

   • The drill bit penetrates the work material, removing material in the form of chips.

4. Safety & Protection

   • The covering encloses critical components, protecting the mechanism and operator.

5. Assembly Integration

   • The assemblies (iris.SLDASM, my assembly drilling 2.SLDASM) integrate all components into a complete, functional drilling unit.

🎯 Applications

• Educational demonstration of drilling mechanism design.
• Basis for further simulation (stress analysis, FEA).
• Adaptable to mechanical projects requiring rotary cutting tools.
