back rake meaning

• [Design engineering]
  An angle on a single-point turning tool measured between the plane of the tool face and the reference plane.

• There are two rake angles, namely the back rake angle and side rake angle, both of which help to guide chip flow.
• Brass for example requires a back and side rake of 0 degrees while aluminum uses a back rake of 35 degrees and a side rake of 15 degrees.
• Back Rake is to help control the direction of the chip, which naturally curves into the work due to the difference in length from the outer and inner parts of the cut.
• Side Rake along with back rake controls the chip flow and partly counteracts the resistance of the work to the movement of the cutter and can be optimized to suit the particular material being cut.
• Legroom is ample for a small midengine car ( compared with the cruelties of the X1 / 9, for instance ), allowing you to move the seat up for a few degrees of seat-back rake.
• If you've ever had a shovel snap in two while digging a hole, injured your back raking leaves or ended a day in the yard with blisters on your hands, you know it's worth investing in the right gardening tools.
