Unit 275 Contour Slot
The Contour Slot unit is used to machine open and closed contour slots
that you defined in an .HC program or generated with the DXF converter.
Parameters on the overview form:
U T : Tool number or name (switchable via soft key)
U S : Spindle speed [rpm] or cutting speed [m/min or ipm]
U F : Feed rate for plunging [mm/min], FU [mm/rev] or FZ [mm/tooth]
U F : Feed rate for milling [mm/min] or FU [mm/rev] or FZ [mm/tooth]
U Type of milling : Climb milling, up-cut milling or reciprocating
machining
U Slot width : Enter the slot width; If you enter a slot width that equals
the tool diameter, the TNC will only machine the contour outline.
U Infeed per rev. : Value by which the TNC moves the tool in the
machining direction per revolution
U Top surface coordinate : Workpiece top-surface coordinate; the
entered depths are relative to it
U Depth : Milling depth
U Plunging depth : Infeed per cut
U Allowance for side : Finishing allowance
U Contour name : Name of the contour file (.HC) to be machined. If the
DXF converter option is available, you can use it to make a contour
directly from the form.
