A J-groove is formed either with special cutting machinery or by grinding the joint edge into the form of a J. Although a J-groove is more difficult and costly to prepare than a V-groove, a single J-groove on metal between a half an inch and three-quarters of an inch thick provides a stronger weld that requires less filler material. Double-J ...
The Maxwell Kinematic system consists of three V-shaped grooves that are oriented to the center of the part, while the mating part has three curved surfaces that sit down into the three grooves. [1] Each of the three v-grooves provides two contact points for a total of six. This design benefits from symmetry and therefore easier manufacturing ...
A through groove (left) and a stopped groove. In joinery, a groove is a slot or trench cut into a member which runs parallel to the grain. A groove is thus differentiated from a dado, which runs across the grain. [1] Grooves are used for a range of purposes in cabinet making and other woodworking fields.
Being mindful of these grooves improves your efficiency at the keyboard, increasing your typing speeds so you don’t have to constantly glance down at your hands," explains Brooke Nelson for ...
In manufacturing or mechanical engineering a groove is a long and narrow indentation built into a material, generally for the purpose of allowing another material or part to move within the groove and be guided by it. Examples include:
The recessed region is bounded by a deep choke trench (or ditch or groove) cut into the face of the flange. Choke flanges are only used with rectangular waveguide, and are invariably pressurizable, having a gasket groove encircling [3] the choke ditch. The presence of these two concentric circular grooves makes choke flanges easily recognizable.
Spiral groove bearings were used most successfully in inertial gyroscopes for planes and ships. [9] In this application, the spiral groove bearings were made of boron carbide ceramic and the grooves were manufactured by ION beam. The bearings were very successful, with MTBF values over 100,000 hours and stop-start capability of 1,000,000 times ...
Solid parquet boards with grooves on the near ends. Tongues on the right sides of the boards and grooves on the left sides. The far ends are tongued. Tongue and groove is a method of fitting similar objects together, edge to edge, used mainly with wood, in flooring, parquetry, panelling, and similar constructions. Tongue and groove joints allow ...
