11 Programming of Cycles
11.1 General information
Cycles etc. can be created manually (without computer) using the @ code. Difficult problems
are solved with the WS 800 A configuring workstation in the CL800 programming language.
The following machining cycles are available in the user memory submodule (UMS) as
permanently stored subroutines:
SINUMERIK 880T:
• L93 Grooving cycle
• L94 Undercut cycle
• L95 Stock removal cycle with relief cutting elements
• L96 Stock removal cycle without relief cutting elements
• L97 Thread cutting cycle
• L98 Deep-hole drilling cycle
• L99 Chaining of threads (4-point thread cutting cycle)
SINUMERIK 880M:
• Drilling cycles L81 to L89
• L900 Drilling patterns
• L901 Milling pattern ”GROOVE”
• L902 Milling pattern ”ELONGATED HOLE”
• L903 Milling rectangular pocket
• L904 Milling pattern ”CIRCULAR GROOVE”
• L905 Drilling pattern ”SINGLE HOLE”
• L906 Drilling pattern ”ROW OF HOLES”
• L930 Milling circular pocket
For the SINUMERIK 880T/M various measuring cycles are additionally available as an Option.
In addition to the possibility of checking the dimensional accuracy of the workpiece, measuring
with a CNC machine offers further applications:
• Detection of tool breakage
• Measuring of the tool geometry
• Determination of workpiece clumping tolerances
• Compensation for factors influencing machining etc.
