CNC Price Estimation Tool: Instant STP File Cost Calculator for Turning, Milling & Laser Cutting
CNC machining cost estimation often wastes hours on manual quotes and inaccurate guesses. MechSkills’ new tool delivers instant, model-based pricing for turning, milling, and laser cutting directly from your STP file.
Key Problems Solved
Engineers and shops struggle with time-consuming RFQs, overlooked features driving up costs like tiny radii or deep pockets, and poor collaboration between designers and machinists. Manual BOM checks and input gathering drain energy, leading to rework and uncompetitive bids. This tool automates estimates, spotting visible model issues early to cut quoting cycles from days to seconds.
A recent Discord comment highlighted frustration with “spreadsheets and waiting” for quotes—our tool responds by analyzing STP files instantly, inspired by community feedback on faster workflows.
Value
Get precise costs without spreadsheets: material, machining time, tooling wear, and derived needs like tool replacements. Unlike basic calculators requiring manual inputs, it reads your STP model’s mass and geometry for tailored breakdowns on turning (simple parts now), milling, and laser cutting. Pro version handles complex models with PDF drawings for tolerances and threads—enterprise-ready accuracy at a fraction of enterprise software prices.
How It Works
The algorithm extracts the STP model’s mass to proportion roughing and finishing operations. It assigns realistic times based on visible features, calculates material cost, total machining time, and extras like tool consumption. Current version excels on simple turning/milling; upcoming update integrates PDF drawings to detect roughness, dimensional tolerances, threads, boosting precision for complex parts.
Upcoming PDF Integration
The next version introduces PDF drawing upload with OCR technology to extract critical details invisible in STP models alone. It will detect threads, surface roughness (Ra values), dimensional tolerances, GD&T symbols, and fits, dramatically improving estimate accuracy for complex parts. This bridges the gap between 3D geometry and 2D specs, making quotes production-ready without manual input.
