CYLINDER SURFACE (Cycle 27, software option 1)
Cycle 27 CYLINDER SURFACE enables you to program a cylindrical contour
in only two axes, as if in a plane. The TNC then rolls it onto a cylindrical
surface.
8 Define a contour in a subprogram and list it in Cycle 14 CONTOUR
GEOMETRY
8 CYCL DEF: Select Cycle 27 CYLINDER SURFACE
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
8 Dimension type: Q17. Degrees = 0; mm/inch = 1
The TNC and the machine tool must be specially prepared by
the machine tool builder for the use of the 27 CYLINDER
SURFACE
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. 1024 line segments.
