ABSTRACT:
A method and apparatus for shaping semiconducting crystals for utilization in force and pressure measuring devices by chip removing machining of at least one surface portion of the crystal member. The shaping is effected by mounting the crystal member to be shaped and a ground cutting tool with respect to one another and rotating and contacting the tool and crystal member with respect to one another so as to remove a surface portion from the crystal. In this manner, many individual crystals can be shaped in an identical manner with high accuracy and with substantially no wear of the cutting tool.
