6 Steps for Tolerance Calculation of Shaft Drawing with Din ISO 286 IT Grades and Fundamental Deviation Symbol

Fig.1: Typical Shaft Drawing Showing ISO 286 Tolerance & FD Symbol

Do you feel uncomfortable reading those shaft drawings with diameter values followed by the symbols like h8 or g5?   These symbols are combination of fundamental or basic deviation symbol and tolerance grades IT numbers and follows DIN ISO 286 standard. How?   Side Note: ISO 286 standards is equivalent to other national standard like …

DIN ISO 286 Standard Tolerance Zone Size Table for Different IT Grades and Nominal Size

Reading the drawings with fundamental deviation (FD) symbols (like g, h or G, H etc) and IT grades will require ISO FD table and DIN ISO 286 fundamental or standard tolerance table. By the way, the ISO 286 standard is equivalent to other national and international similar standards like JIS B 0401, BS EN 20286, …

Applied Mathematical Modeling of SISO Physical Mechanical System – Part1 –Developing System Equations

SISO Physical Mechanical System Representation

Developing system equations is the important first step for finding solution of a physical mechanical system. Here, I will discuss the procedure for creating the system equations to model a Single Input Single Output (SISO) mechanical system.     Example: Find out the displacement [x (t)] with respect to time for the mass m for …
