Drill/mill on the diametric part of the workpiece in Lathe (tracyl) Siemens 840D sl

Drill on the diametric part of the lathe workpiece(G19)

How it’s done,

Y Rotation (Much more on this later)

Z Distance in longitudinal (standard Lathe Z direction)

X depth (Diameter-dimensions).

Starting codes:

Besides the usual...

SETMS (1.. 4); The number of the driven spindle

TRACYL (50); Choice of machining on the diametric surface and diameter of the workpiece

Y will be the length of the diametric surface in mm or inch. (the rotation)

For example, if you have a diameter of 50mm, work out the perimeter and use these dimensions, 50xPi = 157,07963267948966192313216916398

This represents a whole 360 deg turn, use this for suitable split values between holes.

Example of 4 holes around a 50 detail
