Walter Feeds & Speeds vs Hole Pattern Programming App

Walter Feeds & Speeds is an intuitive app for determining base feed rate and cutting speed values. The app covers variety of machining operations in the field of Turning-, Drilling-, Threading- and Milling tools with indexable inserts. The intuitive navigation, from machining operation, work piece material, tool type and further parameters, will help you to determining the feed rate and cutting speed values.

Hole Pattern Programming App is a powerful, professional, and easy-to-use app designed for engineers, machinists, VMC programmers, VMC operators, CAD designers, fabrication professionals, and students who require accurate, error-free hole layout calculations and VMC programming support. The app supports virtually every type of hole arrangement — from simple linear rows to advanced multi-PCD mesh structures. Whether you are working on flanges, plates, jigs, fixtures, decorative panels, or precision mechanical parts, this tool simplifies even the most complex drilling and tapping calculations. Simply enter a few key dimensions and the app instantly generates: • Exact X–Y coordinates • Visual preview of the hole layout • Hole sequence numbering • Optional VMC drilling and tapping programs Even if your hole center is not at X0, Y0, you can change the origin and the app will automatically recalculate all coordinates accurately. Supported Hole Patterns • Single and Multiple PCD (Pitch Circle Diameter) • Full circle or limited angular span PCD • Linear patterns (horizontal, vertical, or angled) • Circular bolt circle layouts • Rectangular grids • Border-only hole layouts • Angular linear patterns • Mesh / lattice structures using multiple PCDs Key Features PCD Hole Patterns Create full or partial angular span hole arrangements on single or multiple PCDs. Linear Hole Patterns Generate straight or angled rows of holes at any custom angle. Rectangular Patterns Fill complete rectangular areas or generate holes only along borders. Mesh / Lattice Structures Create complex multi-PCD patterns for structural and decorative designs. Custom Center Adjustment Change origin (X0, Y0) and automatically recalculate all coordinates. Coordinates & Visual Preview Get precise X-Y coordinates with a visual layout of every hole. Hole Sequence Numbering Automatic numbering from 1 to total holes for easy reference. VMC Programming Support Generate ready-to-use drilling, center drilling, and tapping programs. Editable Drill & Tap Parameters Customize drill depth, tap depth, pitch, and sequence. Flexible Output Options Copy coordinates, copy full VMC program, or share using the Share button. Automatic Error Handling If required inputs are missing, the app shows clear messages instead of crashing. Metric & Imperial Units Work seamlessly in millimeters (mm) or inches. User-Friendly Interface Designed for fast use in workshop, field, or office environments. Practical Use Cases Flange & Bolt Circle Layouts – Design precise PCD holes with full or partial spans. Linear Hole Rows – Create straight or angled hole rows on plates and sheets. Rectangular Plates – Fill areas or generate border-only patterns. Mesh / Lattice Designs – Complex structural or decorative layouts. Custom Center Workflows – Adjust coordinates to match machine zero or fixture setup. Workshop & CAD Planning – Use coordinates for manual drilling or CAD input. VMC / CNC Programming – Instantly generate editable drilling and tapping programs. Why Choose Hole Pattern Programming App?
