3.13 Milling rectangular spigots - CYCLE76 (SW 5.3 and later)
Programming example
Spigots
This program allows you to machine a spigot that is 60
mm long, 40 mm wide, 15 mm deep in the XY plane
and with a corner radius of 15 mm. The spigot has an
angle of 10 degrees in relation to the X axis and is
programmed from a corner point P1. When a spigot is
dimensioned with reference to corners, the length and
width must be entered with a sign to define a unique
position for the spigot. The spigot is premachined
with an allowance of 80 mm in its length
and 50 mm in its width.
