CYCLE93 Introduction
With the grooving (CYCLE93) cycle, you can make symmetrical and asymmetrical grooves for longitudinal and face machining on straight contour elements. You can machine both
external and internal grooves.

CYCLE93 Format
| CYCLE93 (SPD, SPL, WIDG, DIAG, STA1, ANG1, ANG2, RCO1, RCO2, RCI1, RCI2, FAL1, FAL2, IDEP, DTB, VARI, _VRT, _DN) |
Parameters
| SPD = Starting point in the facing axis (enter without sign) |
| SPL = Starting point in the longitudinal axis |
| WIDG = Groove width (enter without sign) |
| DIAG = Groove depth (enter without sign) |
| STA1 = Angle between contour and longitudinal axis; Range of values: 0 ≤ STA1 ≤ 180 degrees |
| ANG1 = Flank angle 1: on the groove side determined by the starting point (enter without sign); Range of values: 0 ≤ ANG1 < 89.999 degrees |
| ANG2 = Flank angle 2: on the other side (enter without sign) ; Range of values: 0 ≤ ANG2 < 89.999 |
| RCO1 = Radius/chamfer 1, externally: on the side determined by the starting point |
| RCO2 = Radius/chamfer 2, externally |
| RCI1 = Radius/chamfer 1, internally: on the starting point side |
| RCI2 = Radius/chamfer 2, internally |
| FAL1 = Finishing allowance at the recess base |
| FAL2 = Finishing allowance at the flanks |
| IDEP = Infeed depth (enter without sign) |
| DTB = Dwell time at recess base |
| VARI = Machining type; Range of values: 1…8 and 11…18 |
| _VRT = Variable retraction distance from contour, incremental (enter without sign) |
| _DN = D number for 2nd edge of tool |
CYCLE93 Examples
CYCLE93 CNC Program Example – 1 – Plunge Cutting
This program is used to produce a groove externally at an oblique line in the longitudinal direction. The starting point is on the right-hand side at X35 Z60. The cycle uses tool offsets D1 and D2 of tool T1. The cutting tool must be defined accordingly.
