CNC Lathe Machine DLC – Precision Meets Automation!

Take your machining skills to the next level with the CNC Lathe Machine DLC for Milling Machine Simulator! This expansion introduces Computer Numerical Control (CNC) turning, allowing you to program and execute precise, automated machining operations just like in real workshops.

Key Features:

• Advanced CNC Functionality – Program your turning operations using a realistic G-code system, bringing authentic CNC control to your projects.

• Precision & Automation – Utilize CNC technology to execute complex toolpaths with efficiency and accuracy.

• Interactive CNC Interface – Operate a detailed CNC control panel with adjustable parameters, step-by-step execution, and dynamic feedback.

• Realistic Tooling & Setup – Choose the right tools and settings to achieve optimal cutting results, just like in real-life CNC machining.

Whether you're experienced in machining or just starting out, this DLC brings an exciting new level of depth to Milling Machine Simulator. Master CNC operations and see your programmed toolpaths come to life!

Real CNC G-Code — Straight From the Lathe

Program the CNC Lathe with authentic, Fanuc-style G-code. Type single commands into the MDI line or run a full turning program — every pass is simulated with real-time, GPU-accelerated voxel material removal, so you watch your part take shape exactly as your code cuts it.

Motion & Interpolation

• G0 – Rapid positioning

• G1 – Linear feed move (turning & facing)

• G2 / G3 – Circular interpolation (CW / CCW), by I/K center or R radius

• G32 – Single-point thread cutting (spindle-synchronized feed)

• G4 – Dwell (P milliseconds or X seconds)

• G28 – Return to machine zero

Planes, Units & Positioning

• G18 / G17 / G19 – XZ / XY / YZ plane selection (XZ is the lathe default)

• G20 / G21 – Inch / Millimeter units

• G90 / G91 – Absolute / Incremental positioning

Feed & Spindle Modes

• G94 – Feed per minute

• G95 – Feed per revolution

• G96 – Constant Surface Speed (CSS) — rpm tracks diameter automatically

• G97 – Constant spindle speed (fixed rpm)

• G50 – Clamp maximum spindle rpm for CSS

Work Offsets & Coordinate Systems

• G53 – Machine coordinate system

• G54–G59 – Six work coordinate systems

• G10 – Programmable offset setting (L2 / L20)

• G43 / G49 – Tool length compensation (apply / cancel)

Turning Cycles

• G71 – Longitudinal roughing (Z-parallel passes stepping in X)

• G72 – Facing roughing (X-parallel passes stepping in Z)

• G70 – Finishing pass along the defined profile

• G76 – Multi-pass threading cycle

Drilling on Center

• G81 / G82 / G83 – Drilling, drilling with dwell, peck drilling with chip clearing

• G84 – Tapping with synchronized spindle reversal

• G85 / G86 / G87 / G88 / G89 – Boring cycle variants

• G80 – Cancel cycle · G98 / G99 – Retract to initial Z / R plane

Spindle, Turret & Coolant (M-Codes)

• M3 / M4 / M5 – Spindle CW / CCW / stop

• T – Turret tool change with tool offset

• M8 / M9 – Coolant on / off

• M0 – Program pause

• M2 / M30 – Program end (with / without rewind)

Subprograms

• M97 – Local subprogram call (with repeat count)

• M98 – External subprogram call

• M99 – Subprogram return

Macro Programming (Parametric G-Code)

Go beyond static programs with full Fanuc-style macro support:

• Variables – #100 = 10 + 5, then use X[#100 / 2] inline

• Math functions – SIN, COS, TAN, ASIN, ACOS, ATAN, SQRT, ABS, ROUND, FIX, FUP, LN, EXP

• Operators – Full arithmetic, comparison and logic in expressions

• Flow control – IF [cond] GOTO n, IF [cond] THEN #var = expr, and nestable WHILE [cond] DOn … ENDn loops

Built for Learning

• MDI mode for quick single-line testing

• Full program editor with live console feedback and alarms

• Toolpath preview and dry run before you commit metal

• On-screen reference of every supported command with example snippets

From facing and roughing to single-point threading, the G-code you write here is the same G-code you'd run on a real turning center.
