CNC Internal Gear Milling
CNC internal gear milling is a machining process used to produce internal gears using a CNC (Computer Numerical Control) milling machine. It involves removing material from a workpiece to create the internal gear profile. Here is a general overview of the process:
Work piece set up
Secure the workpiece, usually a cylindrical or disc-shaped component, in the CNC milling machine. Ensure it is properly aligned and firmly held in place.
Tool selection
Choose the appropriate end mill or gear milling cutter based on the desired gear profile, material, and other considerations. The cutter should have the correct number of teeth and the right diameter to match the gear specifications.
Program the CNC machine
Use appropriate CAM (Computer-Aided Manufacturing) software to generate a machining program for the CNC machine. The program will define the tool path, cutting parameters, and other instructions for machining the internal gear.
Machine set up
Install the selected tool in the spindle of the CNC milling machine. Set the cutting speed, feed rate, and depth of cut based on the material and tool recommendations.
Begin machining
Start the CNC machine and execute the programmed tool path. The milling cutter will gradually remove material, following the programmed path, to form the internal gear teeth. The machine will move the cutter radially and axially to achieve the desired gear profile.
Coolant and chip management
During the milling process, coolant may be applied to cool the tool and workpiece, and to clear away chips. Proper chip management is crucial to prevent chip buildup and ensure accurate machining.
Inspect and verify:
Once the internal gear milling is complete, inspect the workpiece to ensure the gear profile matches the specifications and meets quality standards. Use measuring tools such as calipers, micrometers, or specialized gear measuring equipment.
