Apparatus and method for cutting a v-shaped groove in a sheet of material

摘要

This invention provides V-shape groove cutting method, V-shape groove cutting unit and V-shape groove cutting machine capable of cutting the V-shape groove easily at low cost. By bringing an upper table (7) and a lower table (9) relatively closer, a work is pinched in cooperation between a first plate pressing tool (FP) and a second pressing tool (15). When a carriage moving unit (21) moves a carriage (19) along a guiding member (15), a V-shape groove cutting blade (17) for V-shape groove cutting mounted on the carriage (19) cuts a V-shape groove in the work. Therefore, a straight V-shape groove can be cut easily. <IMAGE>
