Milling & Machining Calcs — version history

Version 9.1 is focused on one goal: making your best setup work easier to repeat. The calculators are still fast, but now the app does a much better job of helping you save, find, and reuse the numbers that keep jobs moving. This update introduces a cleaner flow across Calculate, Records, Reference, Calendar, and Settings. - iPhone keeps a quick list-and-detail workflow for machine-side use. - iPad gets split views in Calculate and Records so you can review details without losing context. - Search is faster and now reaches deeper across calculators and saved content. - Navigation titles, icons, and row layouts were cleaned up for better glance reading. Calculator coverage is broader, with a clearer structure. - Added Milling Job Planner for material, cutter, diameter, flute count, RPM, feed, and SFM planning. - Added Speeds and Feeds Guide for quick starting values. - Added Plunge Feed Rate calculator. - Added True Position calculator. - Added Tap Drill calculator. - Added Shrinkage Compensation calculator. - Added Unit Converter. - Expanded geometry and layout tools for offsets, kicks, saddle bends, arcs, chords, and segment height. Records are the biggest practical change in this release. Instead of retyping setup notes on every repeat order, you can now keep structured shop history that is easy to search and hand off. - Save calculations with title, material, machine, tool, notes, tags, and timestamps. - Keep both inputs and outputs in each saved record. - Mark favorites to pin proven setups. - Search by title, material, machine, tool, notes, tags, or calculator type. - Sort by recently updated, newest, name, material, or calculator type. - Filter views for favorites, milling jobs, tools, machines, notes, and calculations. - Duplicate records for repeat parts and similar setups. - Share a formatted setup summary. - Remove stale records that no longer apply. Shop Library was expanded so the app works more like a real shop notebook. - Save and maintain tool records. - Save and maintain machine records. - Save and maintain material records. - Save milling job records. - Save setup job records. - Save shop notes. - Save tool wear logs. Reference content was reorganized around searchable data while keeping familiar chart access. - Imperial Tap Drill Table. - Metric Tap Drill Table. - Tap, Thread, and Drill Database. - Drill Size Conversion and clearance drill references. - Pipe Threads and thread references. - Decimal, Fraction, and Metric lookup tables. - G-Code and M-Code reference entries. - Material Machinability database. - Speeds and Feeds database. - Tooling database. - CNC Machine reference. Calendar is now part of the daily workflow. - Browse saved work by date. - Review activity for today, this week, this month, selected date, or favorites. - Track what was calculated, saved, and changed on real production timelines. Multiple calculation fixes were included to improve trust in layout and bend outputs. - Corrected conduit offset distance using D = H / sin(theta). - Corrected straight pipe kick distance using D = H / sin(theta). - Corrected straight pipe kick total length behavior. - Corrected compound offset rotation handling. Quality and reliability work was expanded as well. - Added automated test coverage for compound offset layout, conduit offset bend, parallel offset bend, and straight pipe kick. - Improved persistence error handling so failures surface as readable messages. - Preserved existing saved milling jobs while introducing the expanded record model. - Improved migration readiness for Core Data growth. - Updated empty states across Records, Reference, and Calendar. This version is built for how shops actually run: calculate quickly, save what worked, find it fast, and hand off cleaner setup details with less rework between shifts.
