To effectively address the challenges associated with CNC milling titanium, several strategies can be implemented:

Specialized Cutting Tools:

• Employ high-quality cutting tools designed specifically for machining titanium, such as carbide or ceramic inserts.
• Ensure that the tools have sufficient hardness, wear resistance, and heat resistance to withstand the demanding conditions.
• Consider using coated tools to improve tool life and surface finish.

Optimized Cutting Parameters:

• Carefully select cutting parameters like spindle speed, feed rate, and depth of cut to minimize heat generation and tool wear.
• Use lower cutting speeds and higher feed rates to reduce heat buildup and improve chip evacuation.
• Employ interrupted cutting techniques to manage heat generation and prevent work hardening.

Effective Cooling:

• Apply a high-pressure coolant to the cutting zone to dissipate heat and lubricate the cutting tool.
• Use a coolant with high heat transfer properties and good lubrication characteristics.
• Consider cryogenic cooling techniques to further reduce heat generation and improve tool life.

Proper Workholding:

• Use a rigid and stable workholding system to minimize workpiece vibration and deflection.
• Employ fixtures that can effectively clamp the workpiece without causing distortion or damage.
• Consider using vacuum chucks or magnetic fixtures to provide secure and reliable workholding.

Chip Evacuation:

• Design tool paths and cutting strategies to promote efficient chip evacuation.
• Use high-pressure coolant to flush chips away from the cutting zone.
• Employ chip breakers or chip splitters on the cutting tool to reduce chip length and improve evacuation.
