Siemens CNC | CYCLE82 | Drilling and Counterboring

In this article, we describe how to use CYCLE82 to drilling and counterboring in Siemens CNC controlled machines with all details and examples.


CYCLE82 Introduction

The tool drills at the programmed spindle speed and feedrate to the specified final drilling
depth. A dwell time can be allowed to elapse when the final drilling depth has been reached.

Supported CNC Series

Siemens CNC 802D, 810D, 840D, 840D sl, 840Di, 840Di sl series controllers.

CYCLE82 Format



RTP = Retraction plane (absolute)
RFP = Reference plane (absolute)
SDIS = Safety clearance (enter without sign)
DP = Final drilling depth (absolute)
DPR = Final drilling depth relative to the reference plane (enter without sign)
DTB = Dwell time at final drilling depth

Repeat the Cycle

To repeat the cycle in more than one position, MCALL must be written at the beginning of the cycle. The MCALL command is active until the next call. If it is written after positioning the command, MCALL will be canceled.

MCALL Example

X30. Y20.;
MCALL CYCLExx …….. ;
X10. Y10. ;
X-140. Y35. ;

CYCLE82 Examples

CYCLE82 CNC Program Example – 1

The program machines a single hole of a depth of 27 mm at position X24 Y15 in the XY
plane with cycle CYCLE82.

The dwell time programmed is 2 s, the safety clearance in the drilling axis Z is 4 mm.
