Calculator for Complex Field vs Dividing Plate Generator

Your input to this app will be a natural math expression, and the answer will appear in a separate line. This makes it easy to revise current input to get an updated result. Up to 20 of your inputs will be automatically saved and can be reused later. You can also save your answer and incorporate it into your input expressions later. Undo and redo buttons will help you edit your expressions. All mathematical operations are performed in the complex field. Output will be a real or a complex number depending on your input and the selection is automatic. Three output formats are available for you to select: Fixed point, scientific and engineering. The number of decimal digits is adjustable. Finally, the help and demo buttons will bring you quick and easy usage examples. Current version includes the following math functions: exp, log, log10, sin, cos, tan, sinh, cosh, tanh, asin, acos, atan, asinh, acosh, atanh, abs, angle, real, imag and power (^).

Dividing plates are used with indexing heads to precisely divide a circle for machining tasks like cutting gear teeth or drilling bolt-hole patterns. This app generates full‑scale dividing-plate templates (SVG or PDF) that you can print as drilling guides. Full-scale templates: Generate SVG or PDF templates of your dividing-plate design. Configure the plate outer diameter, center hole, mounting holes, ring margins and hole counts. Use custom values or presets for hole counts per ring. Custom geometry: Enter plate dimensions and hole sizes in inches or millimeters. Include optional 3–6 mounting holes on a specified bolt circle. Preview inner/outer ring margins and indexing hole diameters as you edit. Live preview: See a real-time on-screen preview of the plate drawing. Pinch to zoom and pan to inspect details. Toggle dimension markers, concentric ring outlines and hole indicators on or off for clarity. Export & print: Export your design as a full-scale PDF or SVG file. Print the PDF at 100% scale (no printer scaling) for an accurate drilling template. For large plates, use poster-print mode or split over pages. Built-in calculators: Includes a bolt‑circle hole pattern calculator, a simple indexing calculator, an angle converter and a chord-length calculator. These tools help plan hole layouts and gear indexing on the fly. Help & tips: The in-app Help provides usage instructions and printing tips (e.g. always print at 100%). Ideal for machinists and hobbyists using lathes, mills, CNC or DIY equipment. Download now to design precise drilling templates in minutes!
