I fully understand. Apart from the monetary cost of buying another package you then need to spend time and effort learning how to use it. > No, that point will move, if the head rotates around C and the head is > tilted around B axis. > I believe that some additional work with kinematics module will solve > this issue and EMC will calculate all the necessary compensating moves > Theoretically you should be able to do it all with kinematics but it could be tricky to implement. You would have two options: 1) As you suggested, set B to the kerf angle then rotate C to be tangential to the cut path 2) Have A as tilt left/right and B as tilt front/back then use kinematics to operate both axes as you cut. The kinematics would have to offset X and Y as it tilts A and B. This would be a variation on the standard 5 axis kinematics. > My apologies, i do not completely understand, what did You mean by > this question :) > If you are using scheme 1 above you need a joint on the nozzle that can handle rotation as the C axis rotates. A rotary joint then can handle waterjet pressures is likely to be very expensive. I suppose you could mount the nozzle assembly in a bearing so the nozzle itself does not rotate.
