for examples of how machines _might_ use thes axis: http://www.cnc-toolkit.com/cnc_machines.html there are many classic machine tool configurations sometimes the ABC merely 'pose' the part often, 2 angular axis are sufficient, and 3 are not necessary sometimes the ABC are interpolated, depends on the cnc control the UVW are sometimes used to move the xyz work space about in a large envelope,or W might simply adapt Z by moving the spindle stroke range into the work zone. UV can oscillate the spindle ( EDM orbiting or trochoidal machining) google up an xy turntable mounted on a bridgeport to see a crazy way to mill pockets in a mold base (thats xyz c uv) The array of combinations is large. try google images for 'multi axis cnc' remember basics: some machines spin the tool and hold work still (mill, grinder, drill) some machines spin the work and hold tool still (lathe) some machines dont spin anything (punch, EDM) and more variants than this short list HTH tjtr33 tomp xyzab are common, example: part is rotated and tilted by ab mounted above xy table or part is aligned to xy travel on xy table but spindle has yaw and pitch ( google nutating head) the C is used insink edm to turn tool to an angle to the X axis (eg radial array of slots) ------------------------------------------------------------------------------ "Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE Instantly run your Selenium tests across 300+ browser/OS combos.
