CYLINDER SURFACE (Cycle 27)
The TNC and the machine tool must be specially
prepared by the machine tool builder for the use
of Cycle 27.
This cycle enables you to program a contour in two dimensions and
then roll it onto a cylindrical surface for 3-D machining.
The contour is described in a subprogram identified in Cycle 14
CONTOUR GEOMETRY.
The subprogram contains coordinates in a rotary axis and in its
parallel axis. The rotary axis C, for example, is parallel to the Z axis.
The path functions L, CHF, CR, RND are available.
The dimensions in the rotary axis can be entered as desired either
in degrees or in mm (or inches). You can select the desired
dimension type in the cycle definition.
Before programming, note the following:
The memory capacity for programming an SL cycle is
limited. For example, you can program up to 128 straight-
line blocks in one SL cycle.
The algebraic sign for the depth parameter determines
the working direction.
This cycle requires a center-cut end mill (ISO 1641).
The cylinder must be set up centered on the rotary table.
The tool axis must be perpendicular to the rotary table. If
this is not the case, the TNC will generate an error
message.
Pre-position tool in X-axis (Y for spindle axis) on rotary
table center before the cycle call.
This cycle can also be used in a tilted working plane.
The TNC checks whether the compensated and non-
compensated tool paths lie within the display range of
the rotary axis, which is defined in Machine Parameter
810.x. If the error message „Contour programming
error“ is output, set MP 810.x = 0.
