High-precision parts can be made accurately and affordably using the subtractive ᴍᴀɴufacturing process known as computer numerical control (CNC) machining. For the purpose of producing a precise finished product out of materials like plastic, metal, and composites, CNC machining use cutting tools to remove extraneous raw material from workpieces. Product teams now have a variety of alternatives for multi-axis machining, including 3-axis, 5-axis, and even 9-axis machining. What distinguishes one group from the others? The two common ᴍᴇᴛʜods of CNC machining will be compared and contrasted in this article, and it will be explained when it would be preferable to utilize one over the other.
Five directions are possible for a tool to move in 5-axis machines: X, Y, Z, as well as A and B, around which it rotates. A 5-axis CNC machine eliminates the need to ᴍᴀɴually move the workpiece between procedures by allowing operators to approach from every angle during a single operation. Time-effective 5-axis CNC machining is the best technique for producing accurate, complex parts for the aerospace, oil & gas, and medical industries. Product teams need to be aware of a few different types of 5-axis machines, including mill turning CNC centers, continuous 5-axis CNC machines, and indexed 5-axis CNC machines.
Indexed 5-axis CNC machining is similar to 3-axis CNC milling in that the cutting tool is only moved along three axes and does not stay in constant contact with the workpiece. However, in between operations, the cutting table and tool head can automatically swivel in two directions. It is simple to make housings, jigs, and fixtures with the help of indexed 5-axis machining. Regarding speed, accuracy, and the capacity to handle complex geometries, it falls between continuous 5-axis CNC machining and 3-axis CNC milling.
Continuous 5-axis CNC machining boosts productivity and makes it possible to build intricate shapes with organic surfaces by allowing the workpiece and cutting tool to move and rotate simultaneously. Continuous 5-axis CNC machining improves dimensional stability, speed, and surface polish but has the greatest cost per product.
