About this app

"Tired of calculating manually from blueprints? Now, get perfect absolute coordinates in just 1 second with your smartphone!"

Created directly by an active machining technician with the field in mind.
CNC Master CALC is a 'professional practical machining coordinate calculator' born for technicians struggling in CNC lathe and machining environments. For complex taper (slope) and arc (R) machining, it perfectly applies Tool Nose Radius (Nose-R) compensation to instantly provide precise coordinates without a single margin of error.

Go beyond a simple calculator and meet your perfect machining partner that relieves stress in the field!

1️⃣ Taper & Groove Machining Precision Compensation
Handle the most frequent and tricky slope machining without mental math.
🔹 Entry Point X/Z Calculation: Precisely calculates the virtual cutting edge intersection coordinates when offsetting the drawing line by the Nose-R, with zero errors.
🔹 Auto-Compensate Z Clearance Start Point: When setting the safe distance (Z clearance) before entry, it tracks the slope angle to automatically calculate the exact entry X-axis coordinate.
🔹 Complex Double Taper: Calculates continuous taper shapes with changing angles seamlessly in one go.
🔹 Groove Multi-Stage Machining: Supports stepped multi-stage machining coordinates reflecting the groove tool insert (T value) and an area invasion warning system.
🔹 Reverse Machining Support: Fully supports cutting edge inversion for both left/right bidirectional machining and reverse tool (Rev. Nose-R) setups.

2️⃣ Complex Multi-Round (R) Perfect Control
Provides 3 customized calculation modes to perfectly handle any drawing.
🔹 Tangent Mode Calculation: Uses trigonometry to precisely extract the exact tangent point where the arc and slope meet.
🔹 Compound R Trajectory Calculation: Combines the drawing R and Nose R to perfectly calculate the actual trajectory of the tool arc.
🔹 Manual Mode (CAD 3-Point Arc): Easily handles complex non-standard shapes through the CAD 3-point arc method.
🔹 Real-time Shape View: Instantly and intuitively verify on the screen if the entered data matches the drawing.

3️⃣ Right Triangle Unknown Calculator
No need to open CAD or tap a scientific calculator for missing dimensions on the blueprint.
🔹 Instant Unknown Calculation: Simply enter two known values among base, height, hypotenuse, and angle to find all remaining dimensions in 1 second.
🔹 Instant Coordinate Integration: The calculated dimensions can be immediately utilized as the X, Z coordinates required in the actual machining field.

4️⃣ Turn-Mill Polar Coordinate (G12.1) Polygon Machining
🔹 Newly supports the generation of polar coordinate turn-mill polygon machining programs utilizing the CNC X-C axis.
🔹 Drastically increase work safety by previewing the generated machining path with a 2D simulation.

5️⃣ G76 Threading Composite Cycle Generation & Precision Analysis
🔹 Eliminates the cumbersome dimension checking process by automatically linking standard data by thread specifications.
🔹 Threading Precision Analysis Data Provided: Supports precision analysis data according to G76 code usage, allowing perfect verification of even complex thread machining.
🔹 Generates the optimal G76 NC program that can be immediately applied to the field, in the easiest and fastest way.
6️⃣ Material & Cutting Condition Precision Calculator
Supports basic CNC calculations and precise machining analysis by material type, along with integrated cutting condition calculations based on catalogs from the top 5 global drill manufacturers.
