3.1 Basic Machine Startup-Basic Lathe Operator

Once the Power Up Zero Return pop-up window is showing, the next steps are:

Open the door, and check that the tool turret is clear to rotate, and will not interfere with the chuck

If you find a large clump or mass of stringy chips in the machine, make sure to do the following:

Grab with gloved hands and safety glasses

When the workpiece is loaded into the machine, and you are ready to press Cycle Start, we want to slow down the feedrate of the turret coming toward the workpiece. The video suggests that the correct rapid override key to press is:

5%

The operator should check the air pressure gauge to ensure the air pressure is in the correct range for machine operation. The correct air pressure range is:

85-115psi

After powering on the machine, the next steps on the Haas lathe for start up are:

Cycle the door, turn the E-Stop button to the right, press Reset, and then press Power-Up

Checking the coolant level should be part of your _______ start-up procedure.

Daily

The next key to press is the X key to send both the X and Z axes to the Home position.

False

Once you are ready to start running your part, you will press Cycle Start. The machine will run automatically, unless you stop the machine. There are three ways to stop the machine during operation. The three ways are:

Feed hold, Reset, E-stop

At the start of the day, it is important to check the coolant level of the machine. What are the two ways to check the coolant level on your Haas machine?

Memory key and view coolant readout. Walk to the back of the machine and visually check the coolant level in the tank.

If the tools in the turret are not in a safe position, you can use the ________ to move the turret into a safe position.

The Jog handle wheel

When the tool turret has a clear path for rotation, we press which key to send the tool turret to the Home position?

The T key

After you have homed the machine and are ready to start work for the day, it is important that your machine is clean and ready for work.

True

Once the machine is powered on, the Power-Up Zero-Return window will pop up on the screen. This window guides the operator through "homing" the tool turret and each machine axis in a specific sequence.

True

The most common type of workholding to hold material in a CNC lathe is a hydraulic chuck.

True

The process of sending the machine to the Home Position gives the machine a known starting position for each axis.

True

When checking the tool turret position, it is important that the tools in the turret have a clear path to rotate, and will not crash into the workpiece or the chuck.

True

When the operator starts the day, it is important to check that the main circuit breaker for the machine is in the ON position.

True

When you press the Power On button, the machine will perform a series of diagnostics, and then the red E-Stop light will blink. This is normal start-up activity, and nothing to be concerned about.
