Rake angle is actually I dont know
∅=45°+ α- β∅=shear angleα= rake angleβ= friction angle
Rake angle is usually used for cutting and machining processes. This can vary according to the materials being cut and set-up. The two types of rake angle are the back and side rake angle.
The clear difference between positive and negative rake angles is that for the positive rake angle,the leading edge of the cutting tool is behind the perpendicular of the material to be cut.While the tool leading edge is ahead or beyond the perpendicular for the negative rake angle.

In the geometry of a bicycle, the main angles to consider are the head tube angle, seat tube angle, and fork rake angle. The head tube angle affects steering responsiveness, the seat tube angle influences rider position and pedaling efficiency, and the fork rake angle affects stability and handling.
To make a drag rake from a chain link fence you will need the following materials.One 6 foot by 6 foot section of chain link fence.Two six foot lengths of 1/2 inch galvanized angle iron.14 1/2 inch u-bolts with nuts.One 10-12 foot section of 1/2 inch galvanized chain.2 1/2 inch co-links.Drill holes in angle iron to correspond with dimension of the u-bolt width on one foot center across both pieces of angle iron. Bolt the angle iron to the chain link fence section with the u-bolts. Attach the chain to one end of the drag rake by connecting the co-link to the chain link fence as close as possible to the angle iron and approximately one foot from each edge of the rake.. Note: lay the drag rake flat on the ground prior to attaching the co-links to the fencing material. The angle iron should be resting flat on the ground to provide a smooth leading edge of the rake. Finally connect the two co-links to the length of chain to complete the drag rake.
The value of the relief (and rake) angle effects how the tool cuts into a particular material and the type or size of chip produced. For short: relief angle determines how deep and how rough the tool bites.

The best technique for effectively removing grout with a grout rake is to hold the rake at a slight angle and carefully scrape it along the grout lines, applying gentle pressure to avoid damaging the tiles. Be sure to work in small sections and take breaks to avoid straining your hand.
"We'll rake her from stem to stern", said the pirate captain. "Hand me that rake.", said the farmer's foreman. Is that a comb or a rake? I went outside to rake the leaves. A rake is a garden and lawn tool.
