Climb milling, or thick-to-thin chip formation is the ideal way to make sure you are getting the proper results. It begins with the cutting edge entering the excess material and exiting on the finished surface – meaning the cutter tries to climb over the material, ensuring that thick chips absorb cutting heat, decreasing adhesion from cutting pressure and the thin chip exits effectively. The exception to this is to conventional mill when you have an Alpha case in order to remove the thick harden skin, shearing from the softer surface below to create a clean surface, and then revert back to climb milling once the skin is removed.

Causesof tool wear

Coolant pressure plays an important role in machining titanium. It is a difficult material and generates a significant amount of heat during cutting. Using high-pressure coolant can help reduce chip adhesion by flushing them away from the cutting area and cooling the workpiece and cutting tool. Additionally, using a chip conveyor or other means of automatic chip removal can further improve chip evacuation and reduce the risk of tool breakage.

Tool wearmechanism

Tool wear is a common problem when machining titanium. To prevent tool wear and damage to the workpiece, it is important to monitor your cutting tools regularly and replace them when necessary. You should also adjust your machining parameters if you notice signs of tool wear, such as poor surface finish or increased cutting forces.

Using cutting tools with improved wear resistance, such as those made from advanced materials or with specialized coatings, can also extend tool life. Applying proper cooling and lubrication during machining helps to reduce friction and heat, further preventing wear.

Tool wear occurs naturally during CNC machining due to the constant contact between metal tools and workpieces. As tools are used, they gradually wear down, which can be monitored and managed to optimize their lifespan. However, if left unchecked, tool wear can lead to quality issues in finished parts and even result in broken tools.

Implementing a robust tool wear monitoring system can significantly improve your machining processes. These systems use sensors to measure factors like cutting forces, vibration, and temperature in real-time. By analyzing this data, you can detect early signs of wear and make timely adjustments to prevent tool failure.

Arc In is the steady entry of the tool into the workpiece, while chamfer is the angle at the cutting edge of the tool. Both factors can have a significant impact on the performance of your cutting tool when machining titanium. Make sure when machining to program thick-to-thin-arc instead of a straight path which will help avoid sudden jarring changes in cutting forces. And program your chamfer to avoid unstable left-over materials.

Secondary relief is an additional relief angle ground into the back of the cutting tool, which can help to reduce the risk of chipping or breakage, stabilize cutting edges and increase clearance. This can be particularly important when machining titanium, which can be highly difficult to work on. With todays advanced designs, you’ll find many tools utilizing eccentric ground edges specifically targeted toward titanium. These designs offer the proper clearance behind the eccentric relief. They are very effective and tend to feature a stronger edge and last longer. Kennametal’s HARVI™ III high-performance aerospace end mills are only one example of what is offered in the line.
