TurnAxis‑CNC Lathe Simulation TurnAxis is an industrial training software powered by a full‑featured G‑code simulation engine that replicates real‑world machine‑tool machining workflows. Designed for programming practice, hands‑on operational training and fault‑diagnosis learning, it serves CNC practitioners and learners. Core Features • G‑code Simulation & Machining The software parses standard ISO/FANUC‑format G‑code and executes common commands including linear interpolation, circular interpolation and rough‑turning cycles. It monitors tool movement in real‑time and triggers automatic halt‑and‑alarm upon potential collisions. This helps users detect programming errors in advance and mitigate the risk of tool crashes in physical machine‑shop operations. • Full‑Function Virtual Machine Control Panel Equipped with a complete simulated operation panel, it supports multiple working modes: Edit, Auto, Handwheel, Reference‑point Return and more. Operations such as axis jogging, spindle start/stop, turret indexing and override adjustment are available, allowing users to get familiar with basic lathe workflows and build hands‑on operational muscle memory. • Workholding, Tool Setup & Tool‑setting Workflow Custom workblanks and various turning‑tool parameters are supported. Users can configure work‑piece coordinate systems and tool offsets. A built‑in trial‑cut tool‑setting utility reproduces the full on‑site workflow of workpiece clamping and tool offset calibration prior to machining. • NC‑program Validation & Tool‑path Preview A built‑in code editor supports manual NC‑code authoring and NC‑file import. It detects code errors and visualizes tool trajectories in real‑time, enabling beginners to practice programming and quickly fix program defects. • Workpiece Measurement & Dimension Compensation Adjustment Upon simulation completion, calipers and micrometers are provided for dimensional inspection. Measured values can be linked to tool offset parameters, helping users learn real‑world fine‑tuning techniques by adjusting tool compensation according to finished‑part dimensions. • Fault‑injection Training & Learning Resources Common machine‑tool faults such as spindle overload and turret jamming can be injected into simulation scenarios. Built‑in reference materials include G/M‑code manuals and classic machining examples for self‑paced code learning and fault‑troubleshooting drills. Integrating programming, machine operation, quality inspection and teaching, this software enables CNC lathe training without physical machine‑tools and lowers the barrier to hands‑on CNC learning.
