How is a helix milled from the face side with ShopTurn?
Proceed as follows:
The ShopTurn contour calculator is used to program a circle on the
face side (plane G17) that has the diameter of the required
Specify the infeed in Z in the free input box of the contour
Important: Not only the Z coordinate, but also the coordinates for
X and Y, are entered in this free input box.
The helix cannot be milled unless all coordinates are entered for
The programmed helix will also be displayed in the simulation.
If the production of the helix also requires a defined retraction
of the tool, this will be realized with the input of a subsequent
JobShop, description of work offsets from the part program.
How can work offsets from a part program be described?
Work offsets can be described via the ShopMill/ShopTurn user
interface in the "Tools/Zero - Work offset" screen form, but these
forms cannot be integrated into a part program.
Work offsets can be described from a part program in a G code block
with the following syntax:
$P_UIFR=CTRANS(X,10) ==> G500 X axis 10mm
$P_UIFR=CTRANS(Y,20) ==> G54 Y axis 20mm
$P_UIFR=CTRANS(Z,30) ==> G55 Z axis 30mm
$P_UIFR=CTRANS(X,10,Y,20,Z,30) ==> G54 X, Y and Z axis
$P_UIFR[npv]=CTRANS() deletes all values (offsets and rotations) in
all axes of the progr. offset (npv).
$P_UIFR[npv]=CTRANS(X,value) describes the offset in the X axis,
the offsets in further axes as well as all rotations are
Why do undefined changes occur to MD 34090 of a rotary (modulo)
In certain situations, the controller autonomously changes this
value (modulo compensation).
For example, this can happen during Power On/Off, but also in other
situations if the controller wants to correct the modulo value,
e.g. because the measuring range limit of the encoder is
The speed specified for a lathe equipped with one main spindle and two supports being operated alternately depends on the machining diameter being used by the active support. Each support is located in a separate channel.
The spindle must be specified for both channels (MD20070).The spindle machine data 30552 must be set to 2 (automatic GETD).
The speed for the jointly used spindle can thus be specified from both channels.
M3/M4 has to be programmed in the part program of the respective channel where the spindle is accessed.
Program example for “Speed setting from 2 channels, see appendix.
