What types of machining calculations does Kopo offer?
Kopo offers calculations for spindle speed (RPM) based on cutting speed and diameter, milling feed rate (mm/min) and feed per revolution, surface finish (Ra) based on feed and tool radius, and pre-tapping hole depth with stainless steel adjustments.
Can Kopo calculate mechanical properties like bolt strength and torque?
Yes, Kopo includes calculations for bolt resistance (rupture, elastic limit, shear), tightening torque (Nm) by bolt class, and standard metric thread dimensions from M3 to M30. It also features right-angled triangle trigonometry.
Does Kopo support ISO tolerances and fits?
Kopo supports ISO 286-1 tolerances for bores and shafts, with grades IT3 to IT14. It provides instant results for free, uncertain, tight, and press fits, and includes calculations for ISO 6636 keyways and DIN 471/472 circlips, as well as elastic and cylindrical pins.
What materials and tools are included in Kopo's library?
The app includes 10 predefined materials like steel, stainless steel, aluminum, brass, and cast iron, with properties such as Rm, Young's modulus, HB hardness, and indicative Vc. Users can also create and save custom materials and select from tools like HSS, carbide, ceramic, cermet, and diamond with Vc coefficients.
Does Kopo work offline?
Yes, Kopo is designed to function 100% offline, meaning you do not need Wi-Fi or a network connection to use its features in the workshop.
