If the grooving insert is of the same size as the dimension of the groove then grooving is even more easy, we will make the groove in one go, but if the grooving insert is of smaller width than we have to take depth more than one time. ![]() Now with our grooving tool the groove machining task is just easy. In FANUCOTD CNC system, the CNC lathe has more than 10 kinds of cycle programs, such as G70 and G71, each instruction has its own characteristics, the machining accuracy of the. 1) Make full use of the CNC cycle program. ![]() Reasonable and efficient use of the inherent cycle program. The turning tool will first face the component then it will make a chamfer, after that there is straight turning and then there is arc machining the arc may be machined with R (Radius of arc) or arc can be machined with I and K values of the arc, at the top of arc there is a chamfer, then again straight turning, now there comes the groove but we can’t make grooves with turning tools because of their shape so we will machine the groove with our next tool which is solely made for grooving operations, but at the time we are machining with turning tool so we will just skip this groove and will just machine in straight line, after that there is a taper and again a straight line to be machined. Check the following CNC lathe programming tips.
