Q: The biggest safety concern when programming or setting up the ST20Y Lathe is
- Running the turret into the guarding of the machine or your part
- Having a partner double check your work
- Operating the machine with the lights on
A: Running the turret into the guarding of the machine or your part

Q: The best way to make sure you have adequate clearance is to
- Eyeball it
- Measure with a tape measure
- Jog the machine around the machining area of your part.
A: Jog the machine around the machining area of your part.

Q: For making tool changes when programming live tooling lathes a good practice would be to use the following machine home commands.
- G28 X0 Z0
- G28 U0 Z0
- G28 U0; G28 W0;
- G91 G28 Y0 Z0
A: G28 U0; G28 W0;

Q: When programming a ST20Y another area of concern is cutting tool lengths. When using other cutting tools, make sure you call up the shortest cutting tool.  Then check the longest tool in the program to ensure that there is enough clearance with the guards.
- True
- False
A: True

Q: What should you always check with the live tooling to ensure that there is clearance around the tailstock?
- length of the cutting tools
- coolant
- Drive motors and any other obstacles that might be in the tailstock area.
- Both A and C
A: Drive motors and any other obstacles that might be in the tailstock area.

Q: What are 2 types of live tool holders for CNC lathes?
- Front and side
- Contour and twist-lock
- Axial and radial
A: Axial and radial

Q: Axial tool holder can
- Complete part in one operation.
- Machine on the end of you part.
- Machine complex parts
- All of the above
A: Machine on the end of you part.

Q: If I wanted to machine a helix on the end of my part what tool holder would I use?
- Axial
- 16C collet
- Radial
- Fixture
A: Axial

Q: What code is used to start the live tooling motor?
- G97 P1500 M133
- G96 S1500
- G50 S300
A: G97 P1500 M133

Q: If you are machining a hexagon or square you do not need to enter the radius of the cutter.
- True
- Fasle
A: True
