SL Cycles
CYLINDER SURFACE (Cycle 39, software option 1)
Cycle 39 CYL SURFACE CONTOUR enables you to program an open contour
in only two axes, as if in a plane. The TNC then converts it for a cylindrical
surface.
8 Define a contour in a subprogram and list it in Cycle 14 CONTOUR
GEOMETRY
8 CYCL DEF: Select Cycle 39 CYL SURFACE CONTOUR
8 Milling depth: Q1
8 Finishing allowance for side: Q3
8 Set-up clearance: Q6. Distance between tool and workpiece surface
8 Plunging depth: Q10
8 Feed rate for plunging: Q11
8 Feed rate for milling: Q12
8 Cylinder radius: Q16. Radius of the cylinder

The TNC and the machine tool must be specially prepared by
the machine tool builder for the use of the 39 CYL SURFACE
CONTOUR
Cycle.
„ The workpiece must be set up concentrically on the rotary
table.
„ The tool axis must be perpendicular to the axis of the rotary
table.
„ Cycle 14 CONTOUR GEOMETRY can have only one label
number.
„
A subprogram can hold approx. 2048 line segments.
