Thank you for using Milling Calcs. Your skill and attention to detail make good machining possible, and we appreciate a place in your working day. From a quick spindle speed check to a customer tool trial, keep the numbers and notes you need close at hand. Milling Calcs brings CNC milling calculators, shop reference tables, job planning, and cutting-tool sales records together on iPhone and iPad. Use it at the machine, in the office, or during a customer visit. CALCULATE YOUR NEXT CUT • Find spindle RPM, cutting speed, feed rate, and chip load per tooth. • Calculate feed per revolution and estimate plunge feed. • Work with Imperial and Metric inputs where supported. • Plan milling jobs using material, cutter size, flute count, and cutting speed. • Check material removal rate for a proposed cut. • Estimate cutting force and tool deflection with the Cut Optimizer. • Explore depth and width of cut against an advisory deflection limit. • Share calculation results and return to saved milling jobs. KEEP SHOP MATH WITHIN REACH • Look up tap drills and work through thread engagement choices. • Calculate true position, sine bar height, arc length, and chord length. • Work out offsets, conduit bends, and shrinkage compensation. • Convert common shop measurements. • Browse drill sizes, pipe threads, material machinability, and tooling references. • Find G-code and M-code reference information without opening a browser. MAKE TOOL TRIALS EASIER TO EXPLAIN A promising cutter needs a useful comparison. Record the customer's current process, enter a proposed setup, and keep the evidence with the trial. • Compare baseline and proposed tooling costs. • Include tool life, cycle time, labor, setup time, and customer rates. • Review estimated cost per part and annual savings. • Record trial runs, observations, and photos. • Keep product specifications and price history together. • Carry price sources and effective dates into your comparisons. • Create and share PDF trial reports for the next customer discussion.
