About this app

"Tired of calculating drawings manually? Get perfect G-code absolute coordinates in 1 second on your phone!"

[App Introduction]
Created by an active machining technician with the field in mind!
CNC Master CALC is a professional practical machining coordinate calculator designed for technicians struggling in CNC lathe and machining fields. It instantly calculates start (X, Z) and end coordinates for various taper and arc (R) machining with perfect Nose-Radius (Nose-R) compensation.

1️⃣ Precision Taper & Groove Compensation
Handle frequent and tricky taper machining without manual mental math.

Precision Nose-R Offset: Calculates virtual intersection points by accurately offsetting the drawing line by the nose radius.

Z-Clearance Auto-Compensation: Set a safety distance (Z-clearance), and it automatically calculates the correct entry X-coordinate by tracking the taper angle.

Compound Double Taper Support: Seamlessly calculates continuous taper shapes with changing angles.

OD/ID Multi-step Groove Machining: Supports step-by-step groove machining reflecting the insert width (T-value) and features an area intrusion warning system.

Reverse Machining Support: Fully supports reverse (Left-to-Right) machining and Rev. Nose-R settings for reverse tool holders.

2️⃣ Compound Multi-Radius (R) Tangent Calculation
Precisely calculates complex contact points where arcs meet arcs or tapers.

Tangent Point Extraction: Uses trigonometric logic to calculate perfect tangent points between curves and lines, preventing machining steps/marks.

Continuous R Machining: Provides absolute coordinates for R start/end points to generate smooth G02/G03 paths.

Synthetic R Trajectory: Calculates the actual rolling path of the arc by combining drawing R and nose R.

3️⃣ Right Triangle Calculator
No need to turn on CAD or use a scientific calculator for missing dimensions.

Instant Result: Enter just two known values (base, height, hypotenuse, or angle) to find all other dimensions in 1 second.

Coordinate Integration: Use calculated dimensions immediately for real-world X and Z coordinates.

🚨 [Smart Alarm & Safety System]

[Limit] Alarm: Triggers if the R-value is geometrically impossible for the given segment length or angle.

[Chk NoseR] Alarm: Warns when the drawing R is possible but interference occurs due to the actual nose radius.

Selective Reset: Only clears the field that caused the error, making re-entry fast and easy.

🛠️ [User-Friendly Features]

📱 Optimized UI: A one-page layout for intuitive input while viewing the drawing shape.

📷 Built-in Drawing Viewer: Display a photo of your paper drawing on the screen to compare shapes and prevent input errors.

🌙 Dual Theme Mode: Deep Dark Mode for night shifts and Vivid Light Mode for bright environments.
