Okuma L200 Reference Wiki
A quick reference guide for the Okuma L200 CNC Lathe.
Basic Manual Operation
Jogging
The L200 lathe has two axes of linear motion: X (radial) and Z (axial). In Manual mode, the position of the tool turret can be directly controlled using either the jogging encoder (by selecting one of the axes and a movement rate, then turning the knob) or by use of the rapid jog buttons (see below).
Note: the rate of movement using the rapid jog buttons is limited by the feed/rapid override dial.
Changing Tools
Unlike the Okuma mill, the lathe does not have a tool cabinet. Instead, all tools translate together in a rotary turret, with tools being selected by rotating a turret slot to the cutting position. In manual mode, the active tool can be changed by using the + and - tool change buttons (See below).
Note: Manual tool changes are disabled unless the machine’s X axis is fully retracted
Cutting Manually
With the spindle spun up, manual cutting can be performed by using the jogging functionality.
Probing/Setting Zero
GCODE Operation
Entering MDI
MDI operation is accessed via the MDI mode button on the main display. G and M codes can then be entered via the keyboard. Hitting Enter queues a command for execution, hitting the cycle start button causes the command to be executed. This is true even of G and M codes that only perform logical operations.
Common G and M Codes
- G0 - Rapid move
- G1 - Cutting move
- M3 - Spindle on
- TXXTXXTXX - Switch to tool in turret XX

CAM
CAM for the lathe can be performed in Fusion 360 or HSMWorks. When creating a setup, select “Turning or mill/turn”. Stock should generally be chosen as a fixed-size cylinder. All CAM should be done in inches. If the stock has non-radially symmetric features, select Spun Profile.
Tools are all stored in the cloud Lathe library. Bulk material removal should be done with Turning Profile Roughing cycles. Most finishing can be done with Turning Profile Finishing. Deep recesses will require Grooving cycles.
Part-off should be done with constant RPM instead of constant surface speed.
The turn-milling interpolator can be extremely stupid, watch out if doing multiple discontinuous cuts.
