Max. Ramp Radius

Ramping is a tool entry method whereby the tool enters the part by gradually increasing in depth, preventing any shock loading on the tool to avoid poor tool life or premature tool failure. The angle of entry is determined by a defined ramp angle.

When the cutter approaches at a Ramp Angle less than 90 degrees, it will move in helical motions (see illustration 1 below).

If the Ramp Angle is less than 90 degrees, the following additional parameters are displayed: Min. Plunge Size and Max. Ramp Radius (this parameter is the maximum radius of the helical approach).

If the tool cannot approach using helical motions by the Max. Ramp. Radius, it tries to plunge on the toolpath (see illustration 2 below). If the distance between the segments of the toolpath is smaller than the Min. Plunge Size, the system checks the distance between the current location of the tool and the furthest point of the area to be milled (see illustration 3 below). If this distance is smaller than the Min. Plunge Size, the procedure is not executed and all the subsequent layer milling is cancelled.

(This parameter is set in the Entry & End Points section of the Procedure Parameter Table.)
