CYCLE76 Introduction
Use this cycle (CYCLE76) to machine rectangular spigots in the machining plane. For finishing, a face cutter is required. The depth infeed is always carried out in the position upstream of the semicircle style approach to the contour.

Parameters
The following input parameters are always required.
| _RTP = Retraction plane (absolute) |
| _RFP = Reference plane (absolute) |
| _SDIS = Safety clearance (to be added to the reference plane, enter without sign) |
| _DP = Depth (absolute) |
| _DPR = Depth relative to the reference plane (enter without sign) |
| _LENG = Spigot length, for dimensioning from corner with sign |
| _WID = Spigot width, for dimensioning from corner with sign |
| _CRAD = Spigot corner radius (enter without sign) |
| _PA = Reference point of spigot, abscissa (absolute) |
| _PO = Reference point of spigot, ordinate (absolute) |
| _STA = Angle between longitudinal axis and 1st axis of plane |
| _MID = Maximum depth infeed (incremental; enter without sign) |
| _FAL = Final machining allowance at the margin contour (incremental) |
| _FALD = Finishing allowance at the base (incremental, enter without sign) |
| _FFP1 = Feedrate on contour |
| _FFD = Feedrate for depth infeed |
| _CDIR = Milling direction: (enter without sign) Values: 0: Down-cut milling 1: Down-cut milling 2: with G2 (independent of direction of spindle rotation) 3: with G3 |
| _VARI = Machining type: Values: 1: Roughing to finishing allowance; 2: Finishing |
| _AP1 = Length of blank spigot |
| _AP2 = Width of blank spigot |
Examples
CYCLE76 CNC Program Example – 1
With this program, you can make a spigot with a length of 60 mm, a width of 40 mm, and a corner radius of 15 mm in the XY plane (G17). The spigot has an angle of 10 degrees in relation to the X axis and is programmed from a corner point P1. When corners are used for dimensioning, the length and width of the spigot must be specified with a sign to define the spigot position uniquely. The spigot is premachined with an allowance of 80 mm in length and 50 mm in width.
