Select the line cutter mold these General Principles : Install easy to adjust , good reliability , good rigidity, high durability and precision. Meanwhile , to meet the processing requirements of the premise , try to choose a shorter shank tool to enhance the processing of rigidity.

1, according to the choice of the surface shape of the workpiece cutter mold

During mold processing , the ball ends of the die cutting tool is zero , so as to ensure accuracy , the general use of the cutting tip spaced closely spaced , the ball end mill used in surface finishing. The flat head cutter mold surface quality and efficiency are superior cutting knife ball , so long as the guarantee , but the premise cut , either roughing or finishing surfaces should Select flat knife.

Further , durability and accuracy of the relationship between the tool and the tool a great price , attention is necessary , in most cases , a good choice of the tool while the tool increases the cost , but the resulting processing quality and efficiency , you can greatly reduce the cost of the entire process .

2 , reasonable arrangements for the order cutter mold

In the economical CNC machining process, due to the mold tool wear measurement and replacement , mostly carried out manually , occupied assisted a long time, therefore, must make reasonable arrangements Sort tool . General should follow the following principles :

① processes concentrated in a single setup , the same tool can do all of the processing steps which carried .

② rough finishing tool should be used separately .

③ after the first hole surface .

④ first for surface finishing, finishing the two-dimensional contour .

⑤ rational use of CNC machine tool automatic tool changer features to enhance productivity.

⑥ minimize the number of tools .

3 , according to the size of the workpiece surface mold tool selection

When the mold tool is selected , to make the size of the mold tool and the workpiece surface dimensions are adapted to use . Production, contouring around the flat parts , often using mills ; milling plane , to be elected carbide blade cutter. When processing bosses , grooves, choose high-speed steel milling cutter ; rough machining rough surface or holes , can be used carbide inserts corn milling ; for some three-dimensional contour of the slope surface and variable processing , selection disk -shaped cutter, round nose knife, flat knife to do roughing , selection ball cutter, circular cutter, conical cutters do finishing.
