Advantages of 2.5D machining
– Easy generation of efficient G-code
– Many milling operations can be completed using 2.5 axes
– Drilling and tapping operations are possible on a 2.5-axis mill
– 2.5D objects can be machined on a 3-axis milling machine
Applications of 2.5D machining
– 2.5D machines can perform cutting operations in two of the three axes at a time
– 2.5D machining is less complex than 3D contour machining
– Drilling and tapping centers are often 2.5-axis machines
– CNC routers are another example of machines that use 2.5 axes
– CNC routers can perform basic milling processes
