Thank you for using Milling Calcs. Your skill and attention to detail matter at every setup. Build on that good work with CNC machining calculators, tool trials, shop records, and references in one app for iPhone and iPad and Apple Watch. Check spindle speed at the machine, compare a new tool with the current cut, or prepare for a customer visit. Keep the numbers and the job details together so you can find them when the next order arrives. CALCULATE YOUR NEXT CUT - Find spindle RPM from cutter diameter and cutting speed. - Calculate feed rate, chip load per tooth, and feed per revolution. - Estimate plunge feed and material removal rate. - Plan milling and drilling jobs with material, tool size, and cutting inputs. - Explore estimated cutting force and tool deflection for planning. - Work with Imperial and Metric units. - Convert length, area, solid volume, and liquid volume. SOLVE EVERYDAY SHOP QUESTIONS - Check true position from measured X and Y deviation. - Find tap drill sizes and sine bar setup heights. - Calculate arc length, chord length, and circular segment height. - Work through shrinkage compensation. - Lay out pipe kicks, compound offsets, and conduit bends. - Use a shop calculator with arithmetic, conversions, and local history. COMPARE TOOLS WITH THE FULL COST IN VIEW - Compare baseline and proposed cutting tool trials. - Review tooling, machine, labor, setup, and tool-change costs per part. - Estimate cycle time savings and annual savings from your inputs. - Record tool life, usable edges, tool prices, and production volume. - Keep trial photos, observations, and measured runs with the job. - Share PDF trial reports. KEEP CUSTOMER WORK MOVING - Organize customers, sites, contacts, parts, and applications. - Track trial stages, quotes, next actions, and outcomes. - Set local follow-up reminders when you choose. - Record first orders, purchase orders, quantities, and lead times. - Review reorder forecasts based on your stock and production assumptions. - Maintain local contacts or explicitly import, refresh, and export iOS Contacts. - Keep customer notes and decision-maker details in your sales workspace. SAVE THE DETAILS THAT MAKE REPEAT WORK EASIER - Keep saved calculations and milling jobs close to your shop records. - Maintain tool, machine, and material libraries. - Record setup jobs, shop notes, daily tasks, and tool wear. - Search records, browse categories, and change sort direction. - Build setup sheets for repeat jobs and shift handoffs. - Use supported text, PDF, JSON, and QR setup-sheet sharing. MACHINING REFERENCES WITHIN REACH - Browse Imperial and Metric tap drill tables. - Look up drill sizes, clearance drills, and pipe threads. - Check decimal, fraction, and metric conversions. - Consult G-code, M-code, material, tooling, and machine references. - Review speeds and feeds reference data without opening a browser. YOUR WORK, READY WHEN YOU NEED IT Core calculations, references, records, and the sales workspace work locally without an account or internet connection. Use Today, Tools, Trials, Calculate, and More to move between the day's priorities and the details behind them. - Back up shop data and preview supported imports. - Export sales summaries for spreadsheet review. - Carry customers, contacts, products, trials, photos, and reports in a sales project. - Preview sales-project changes before merging them with existing work. Start with core calculators and reference data. Pro adds advanced calculators, unlimited calculation and shop records, full shop libraries, and PDF, JSON, and QR setup-sheet exports. Bring your experience. Keep useful numbers, trial evidence, and the next action close at hand. For monthly subscriptions: Monthly Pro is a 1-month auto-renewable subscription.
