In the video we discuss that a standard lathe has 2 axis. What axis is is active when the turret moves left to right?
A-axis
Y-axis
Z-axis
X-axis
In the video we discuss the movement of the turret in the up and down direction. What axis is this
Z-axis
A-axis
X-axis
Y-axis
The machine coordinate system defines where the axis can move and how we measure how far the axis have moved
True
False
Home position for the Z-axis on a lathe is when the turret is positioned with:
None of the answers
The Z axis moved to the left side, closest to the spindle
The Z axis moved to the right furthest away from the spindle.
The X axis at the furthest up position away from the operator.
Home position for the X axis on a lathe is where the turret is in which position?
X axis moved to the bottom position
With the x axis moved to its lowest position
None of the above?
With the X axis furthest up away from the operator
The work coordinate system defines the important starting points for the workpiece loaded into the machine.
True
False
In a CNC lathe the cutting tools are stored in
in the tool box
in the tool turret
In a tool tray next to the machine
In the spindle
The function of the tool offset page is
To tell the machine where the cutting tool is in relation to the workpiece
To tell the machine the speed to go
none of these
to tell the machine what parts to make
To set the X axis offset you would
1 - Take a skim
2 - move the tool away
3 - Measure the size you cut
4 - Which button do i press here?
Z face measure button
+Z rapid button
X diameter button
Offset button
Once you have set the X-axis the control will ask you to record the size, is this correct?
Yes
No
It is important to enter the tool offset number into the Haas control as the machine will know where the tool is located.
True
False
Once the tool offsets are in place the workpiece face becomes Z zero
True
False
The centre of the workpiece diameter becomes the new zero position for the X-axis
True
False
The codes that tell the lathe what to do are G-codes and M-codes
True
False
The important G-codes for lathes are
Gee - i forgot
G01 G09 G11
G01 G02 G03
G4 G5 G6
