Machining Center
The Block Data menus on 5000/5020M controls are very similar to the menus on lathe controls.
The four menus are labeled: “CURRENT”, “BUFFER”, “SECOND BUFFER”, and “THIRD
BUFFER” on machining center controls. On some controls the fourth menu is labeled like the
lathe controls, “READ”.
The block data soft key allows the operator to access the menus that show the programmed
conditions of the machine one block at a time. The operator can see what block of information
is being, or will be executed. The “CURRENT” screen shows the program data of the currently
executed block. The left side of the screen shows the G and M codes that are in effect. The
following is a description of the data shown in the Block Data mode on 5000/5020M controls.
X Target value of X axis
Y Target value of Y axis
Z Target value of Z axis
B Target value of B axis
I Programmed I value (radius of cut with respect to the X axis)
J Programmed J value (radius of cut with respect to the Y axis)
K Programmed K value (radius of cut with respect to the Z axis)
F Programmed F value (feedrate)
Fd Feedrate command value (0.001mm/12.8msec)
Ft Feedrate (F1 digit command option)
F1 Feedrate (F1 digit command option)(feedrate setting command)
S Programmed S value (spindle speed)
Tc Active tool number
Tn Next tool number
M M command value
H Tool offset number
D Cutter radius compensation number
Ha Work coordinate system number
Np Hole number in coordinate calculation
Hc Work coordinate system number
The following data is shown on the right side of the screen no matter which menu is
selected in the Block Data mode.
Sr Actual spindle speed
So Programmed spindle speed (overridden)
fm Axis traverse speed in mm/min
fr Axis traverse speed in mm/rev
Pr Programmed number of main program repetitions
Pe Actual number of programs executed
Nr Hole number for restart
Ns Sequence specified by the sequence stop
