Simumerik Control for Four-Axis Turning on Lathes

With two additional parameters, the user expands the machining process for a tool into balanced cutting with two tools. The Sinumerik contour machining cycle automatically creates the CNC sequences.

The expanded contour machining cycle for Sinumerik CNCs now facilitates four-axis turning on lathes. Two turning tools, opposite one another, machine the workpiece simultaneously enabling the machining time to be significantly reduced.

These machining process can be programmed directly on the Sinumerik CNC without a CAD/CAM system. With two additional parameters, the user expands the machining process for a tool into balanced cutting with two tools. The Sinumerik contour machining cycle automatically creates the CNC sequences.

In four-axis machining, a distinction is made between synchronous and asynchronous path control with the channel-based Sinumerik control executing two independent CNC programs simultaneously.

In synchronous machining, which is particularly suited for roughing and finishing, the cutting inserts are exactly opposite one another and move identically. The cutting depth is equally distributed over both cutting edges, making it possible to double the feed rate per revolution and chip volume. In asynchronous path control used for roughing, the two tools move differently.

In longitudinal turning, the cutting inserts work at different diameters, and in face turning, they work at different Z positions. The chip volume relative to a tool can be roughly doubled because of short waiting times for tool synchronization.
