Description
Various insertion modes can be selected – (only for plane-by-plane machining
method and for ∇, ∇∇∇ or ∇∇∇ edge)
Centered G0
•
Centered: Insert vertically in center of pocket
•
The tool executes the calculated depth infeed vertically in the center of the
pocket.
Feedrate: Infeed rate as programmed under FZ
Helical: Insert along helical path
•
The cutter center point traverses along the helical path determined by the
radius and depth per revolution. If the depth for one infeed has been reached,
a full circle motion is executed to eliminate the inclined insertion path.
Feedrate: Machining feedrate
Note: The vertical insertion into pocket center method can be used only if the
tool can cut across center or if the workpiece has been predrilled.
Maximum pitch of helix - (for helical insertion only)
The helix pitch may be lower due to the geometric conditions.
Radius of helix - (only for helical insertion)
The radius must not be larger than the cutter radius, otherwise material will
remain. Also make sure the circular pocket is not violated
Depth infeed rate - (for insertion in center only)
Complete machining
•
The circular pocket must be milled from a solid workpiece (e.g. casting).
Editing
•
A small pocket or hole has already been machined in the workpiece. This
needs to be enlarged. Parameters AZ, and ∅1 must be programmed.
Chamfer width for chamfering - (for chamfering only)
Insertion depth of tool tip (abs or inc) - (for chamfer only)
Depth of premachining - (for remachining only)
Diameter of premachining - (for remachining only)
