Mazak G01.1: Threading with C‑Axis Interpolation – Practical Example

CNC Program

/*MAZATROL MATRIX For INTEGREX IV Programming EIA/ISO
Mazak G01.1 command in the milling mode enables a simultaneous interpolation on the C-axis and
the X- and/or the Z-axis for straight, tapered or scrolled thread cutting of constant leads.

Programming format
G01.1 Zz/Ww Xx/Uu Ff Ss;
Where
Zz, Ww, Xx, Uu: Thread ending point addresses and coordinates (mm or in.)
Ff: Lead of long axis (axis of which moving distance is the longest) direction
Ss: Rotational speed of C-axis (rpm)
Set parameter F111 bit 3 to select the direction of C-axis rotation:
F111 bit 3 =
0 : Normal rotation of C-axis
1 : Reversed rotation of C-axis
