Cone tolerance (2)

1. GB11334 specifies several items for cone tolerance? A: The cone is a multi-parameter part. From the function, the national standard specifies the following four items of conical tolerance: (1) Cone diameter tolerance T_D: It is suitable for cone length L range All cone diameters inside. (2) The taper angle tolerance AT is given by the angle value ATα or the line value AT_D. (3) The shape tolerance T_F of the cone. It includes conic line straightness tolerance and section roundness tolerance. (4) Given a section cone diameter tolerance T_(DS), which applies only to the cone diameter of the given section.

Application of laser ranging in house area measurement
It is understood that the surveying and mapping of commercial housing area is carried out in two stages. First of all, the surveying and mapping personnel measure the estimated area of the house according to the drawings and other materials; after the house is completed, the actual area should be measured. In the actual area measurement stage, the surveying and mapping personnel should conduct household measurement, use advanced equipment of laser range finder to measure the length, width and height of the house, and calculate the inner area of the house according to these data, and conduct common buildings such as stairwells and elevators. Take area measurements. A laser rangefinder is an instrument that uses laser technology to measure.
