Groove

Most grooves have radii at the top and bottom. Groove tool paths are actually quite complex. The following sequence is often used to create a groove that is accurate and with no tool marks.

A common groove operation is shown in the Details view in Figure 8.31:

a) The tool is usually plunged near the center of the groove to rough.

b) Other plunge moves as required to remove excess material.

c) One contouring path, starting outside and moving inward, creating radii and contour.

d) One contouring path, starting from the other side and moving inward finishing the other side.

Rules for Grooving

• Use a groove tool narrower than the groove and with a radius equal or less than the finished radius.

• Use CAD/CAM or lathe control groove cycles to program the grooves.
