5 Axis CNC Machining Centers

Besides the linear axes X, Y and Z, 5 Axis Machining Centers also move in two rotary axes, often identified as A and B axis. The rotary axes tilt the tool with respect to the part. Physically, it can be either the tool that tilts or the part that tilts. True 5 axis CNC machining uses these axes to smoothly follow a contoured surface. This type of machining has long been important in the aerospace industry, where machined parts follow the aerodynamic forms of aircraft. Some machines move the rotary axes only to position the tool or work outside of the cut. A machine capable of this “3+2” machining often can reach all of the machined features of the part in a single setup.

For Large-Part Machining, Five-Axis Capabilities Prove Essential to Staying Competitive

Metalcraft of Mayville’s old milling machine for large parts failed just when the company began seeing increased pressure to take on projects requiring more flexibility and capabilities. Two five-axis HMCs from Toyoda helped the company stay in step with the trend. 

Center of Excellence Is New Twist on Old Manufacturing Department Structure

The new Spirit AeroSystems facility for five-axis machining allows a small team to oversee a significant amount of machining capability. Is this the way of the future as machining systems become more automated?
