Keyway position
 |
by Lampros Georgiou - 29.12.2005
Keyways are essential in machinery design. Torque transferring or rotation fixing at levers, shafts, linkages, power posts and others is provided by a key and a keyway with low cost and reliability.

Internal keyway
 |
by Lampros Georgiou - 27.12.2005
One design principle which every designer must keep in mind is to design difficult to manufacture features with the appropriate cuts (holes and slots) in order to facilitate manufacturing and assembly. |
Airvent
 |

In many cases press-fitted connections can successfully be replaced by bonded (glued) connections. One minor disadvantage of such connection is the liquid state of the glue during installation.

Pin hole location
 |
by Lampros Georgiou - 23.12.2005
One method for securing a shaft in a hole and prevent it from rotation is the usage of a pin. Although this is a very simple design many of us don't know the correct location of the pin hole. |
Methods for correcting wrong center distance between pin holes
 |
by Lampros Georgiou - 19.12.2005 - 1 comments
Many of us have difficulties in final assembly, when we discover that we have wrong center distance between pin holes. How to fix this problem fast, cheap and functional? Read this article. |
Calculating internal radius with known boundaries
 |
by Lampros Georgiou - 14.12.2005
Internal radius in design engineering is a very useful feature. Often we need to add a radius which passes through a given intersecting point (an edge) and tangent to two lines (surfaces). With a cad program such a calculation is a “piece of cake”, but without one, a puzzle.

Spot face milling for precision assembly
 |
by Lampros Georgiou - 11.12.2005
When a designer follows the road of fine mechanics and precision at higher levels, he must concentrate at every detail, every potential source of inaccuracy. Such a source is the elastic deformation due to thread-bolt forces. The solution: a simple spot face.

Dial gauge (comparator) stand error
 |
by Lampros Georgiou - 2.12.2005
When using a dial indicator with a self made or commercial dial gauge (comparator) stand, it is important to place the first vertical to the measurable surface. If the dial indicator positioned with a small angle (due lack of squareness), its reading will not be the true dimension. |
Protection split bushing
 |
by Lampros Georgiou - 2.12.2005
Often in precision assembly (especially in gauging) we need to secure metrology equipment or precision components (which often disassembled) by means of a set screw direct clamping. This kind of clamping (tightening directly with a screw) causes surface deformation, burs and craters.

How to secure a square shape shaft end without a square cut on the mating component
 |
by Lampros Georgiou - 2.12.2005
When we want to prevent the rotation of a shaft we use various methods (pinned, screwed, friction, etc.). One method is to use a shaft with a square shaped end (across flats) and an identical square slot feature on the mating part. |
