iMachining is an Android App designed for machinists, technicians, engineers and student to be used as a machining calculator and also a reference tool for drilling, milling and turning (lathe). It is designed to be very easy-to-use and user-friendly at shops. Features: *** Turning (Lathe) *** - Calculate RPM given Cutting Speed and Cutting Diameter - Calculate Cutting Speed given RPM and Cutting Diameter - Calculate Machining Time given Cutting Length, RPM and Feed/Turn - Metric and Imperial units (mm, inch) *** Milling *** - Calculate RPM given the Cutting Speed and Tool Diameter - Calculate Tool Feed Rate given Feed/Tooth, Tool Diameter and number of tool teeth - Calculate Machining Time given the Feed and Cutting Length - Metric and Imperial units (mm, inch) *** Drilling *** - Find RPM given the Cutting Speed and Tool Diameter - Find Feed Rate given the Cutting Feed (inch/rev) and RPM - Find Machining Time given the cut length and feed rate - Metric and Imperial units (mm, inch) *** Reference Tool: Tap Size Charts *** - Interactive tap size charts - Fractional, Screw Size and Metric Standards - Coarse and Fine threads *** Reference Tool: Drill Size Charts *** - Interactive drill size chart - Fractional, Letter, Wire Gauge and Metric Standards - Drill Size in mm and inches *** Reference Tool: Machining Parameters *** - Interactive machining parameter charts for cutting speed and feed rates for different materials - Machining parameters for different tool materials: HSS and Carbide - Feed rates for milling and turning - Selection between Metric and Imperial units
