Abstract
An apparatus for cutting into a cylindrical munition, comprising a cutting head and a mechanism for moving the cutting head relative to the surface of the munition. The mechanism for moving the cutting head constrains the cutting head to follow a linear path in one direction, to be positioned in use parallel to the axis of the munition, and an arcuate path in the plane normal to the first direction to follow the contour of the munition.
Claims13
An apparatus for cutting into a munition having a casing with a cylindrical external surface and a central axis, comprising a cutting head and means for moving the cutting head relative to the external surface of the casing along a closed path, characterised in that the means for moving the cutting head constrain the cutting head to follow a linear path in a first direction, to be positioned in use parallel to the central axis of the casing, and an arcuate path in a plane normal to the first direction so as to remain at a constant distance from the external surface of the casing, whereby the cutting head cuts a piece out of the casing of the munition without requiring the munition to be moved.
A method of cutting into a munition having a casing with a cylindrical external surface and a central axis, comprising:
- positioning a cutting head in cutting relationship with the external, surface of the casing,
- moving the cutting head relative to the external surface of the casing along a closed path, and
- constraining the cutting head to follow a linear path in a first direction parallel to the central axis of the casing and an arcuate path in the plane normal to the first direction so as to remain at a constant distance from the external surface of the casing.
