Multiaxis machining is a manufacturing process where computer numerically controlled tools that move in 4 or more ways are used to manufacture parts out of metal or other materials by milling away excess material, by water jet cutting or by laser cutting. Typical CNC tools support translation in 3 axis; multiaxis machines also support rotation around one or multiple axis.
There are now many CAM (computer aided manufacturing) software systems available to support multiaxis machining including software that can automatically convert 3-axis toolpaths into 5-axis toolpaths.
Multiaxis machines offer several improvements over other CNC tools at the cost of increased complexity and price of the machine:
The amount of human labor is reduced, if the piece would otherwise have to be turned manually during the machining.
A better surface finish can be obtained by moving the tool tangentially about the surface.
More complex parts can be manufactured, particularly parts with curved holes.
The number of axes for multiaxis machines varies from 4 to 9. Each axis of movement is implemented either by moving the table (into which the workpiece is attached), or by moving the tool. The actual configuration of axes varies, therefore machines with the same number of axes can differ in the movements that can be performed.
Secrets of 5-Axis Machining:
Karlo’s presentation will unlock the mystique of 5-axis machining. It will cover a discussion of the history of multiaxis machining. It will explain configurations and considerations for purchasing a machine. Karlo will also tell you how to setup the equipment and what all the jargon means.
Karlo’s course on eapprentice builds upon the principles laid out in his book and goes even further into the actual principles in CAM, such as cut patterns, tilt angle, tool axis control, machine simulation, and custom applications.
The course shows you step-by-step how to build a virtual machine for simulation and delves into probing with Renishaw Plus.
