How to choose crystal orientation for single crystal diamond tools?

Diamond crystals belong to the cubic crystal system. Due to the difference in atomic arrangement and atomic density on each crystal plane and the distance between crystal planes, the anisotropy of natural diamond crystals is caused. Therefore, diamond not only has different physical and mechanical properties of each crystal plane, but also has different manufacturing difficulty and service life, and the microscopic damage strength of each crystal plane is also significantly different.

The three primary crystal orientation are {111}, {100} and {110} in diamond industry, which described as 3 point, 4 point and 2 point respectively.

Customer case: Size: 1x1x4mm MCD, 0.5x0.5x4mm CVD

Application: Diamond tool

Customer desired 4pt diamond

Generally, if the diamond tool is required to obtain the highest strength, the (100) suitable as tool orthogonal rake and tool clearance; if required to resist mechanical wear, the (110) suitable as tool orthogonal rake and tool clearance; if required to resist chemical wear, the (110) suitable as tool orthogonal rake, the (100) as the clearance, or the (100) for both the front and flank.
