CNC CONTROL PANEL: millwright

Scientific Machinist Calculator (free) Right-triangle solver, bolt hole circle, sine bar/plate, taper calculator, thread math, chip load/MRR, cutting power & torque, surface finish predictor, unit converter, and a scientific keypad calculator. Control Panel Library — 4 → 8 controllers Added Okuma OSP, Heidenhain TNC, Mitsubishi Meldas, Centroid. All 8 now have authentic per-brand button sets and a round, draggable jog handwheel with axis/multiplier controls. Workholding Selector — much deeper 13 part shapes, 23 fixture types, and a real scoring engine that ranks the best fixture for the job instead of hard-coded rules. CAD/CAM Studio — the big one, built in stages Foundation: Sketch a part (parametric shapes or freehand drawing), generate real toolpaths (milling: profile/pocket/drill/facing/slot/engrave; turning: facing/OD-ID/groove/thread/part), preview in 3D, and export G-code posted correctly for all 8 controllers — including genuinely different Siemens and Heidenhain syntax, not just relabeled Fanuc code. Toolpath quality pass: True G2/G3 arcs (not tessellated lines), pocket islands, a full A–Z engraving font, tangential helical lead-in/out arcs, ramping pocket entry, and an adaptive-style spiral clearing option. Solid modeling: Extrude (boss) and Extrude Cut (real material removal — bridged into the stock as an actual hole with a floor plug, not just an overlapping shape) for both parametric and freehand sketches. Latest round — four upgrades at once: Save/Load + Undo/Redo — projects persist to disk now; nothing resets when you leave the screen Complete solid preview — turning gets a real revolve solid, and drilled holes now carve into the part like sketch cuts do Production tools — cycle time estimate, a reusable tool library, auto-suggested feeds/speeds Toolpath playback — scrub through the cut with a moving tool marker
