The ability to achieve the requested
perpendicularity tolerance is affected by the condition of the workpiece before honing, amount of stock to be removed, machine, fixturing and honing tool.
The application of PT zone is recommended where the variation in
perpendicularity of threaded or press-fit holes could cause fasteners to interfere with mating parts.
Perpendicularity was ensured by adjusting the transducer head until the brightest reflection lines from the various corneal layers were observed in real time.

Excessive tool wear produced changing tool geometry and increased cutting forces, which promoted elastic deformation of casting with increasing tilt and destroying required tolerance on
perpendicularity ("tilt").
By contrast, the permeation path of sample without CP was more tortuous because its interfacial area
perpendicularity to the permeation direction of small molecules was larger.
Demonstrate an understanding of parallelism and
perpendicularity of lines and planes in three dimensions
The company's Mitutoyo RA2100 Roundness Tester makes light work of measurements including cylindricity, concentricity and
perpendicularity (as well as other more specialist measurements), added to which, the flexible design of the equipment allows for set-up of an extensive range of different geometries.

25 dg and
perpendicularity of image plane to zenith direction is within 0.
The orthocentric tetrahedron of triangle [8], [7] is a simple construction which gives students a great opportunity for in-depth study of
perpendicularity in space and testing of various methods of proof.
The highly controlled runout and concentricity of the body, and their precise 90 degree
perpendicularity to the workpiece, ensure a high degree of accuracy.
