Mold manufacturers always met the challenges of complex surface machining. Ideal for vertical and near vertical surface of the knife track type and priority level for the level and close to the surface of the knife track there is a big difference. What about using the tool path and the exact decision of applications made by the CNC programmer. These decisions were based on how the surface roughness of molded parts experience and best guess. Traditional approach surface machining The traditional CAM programming, tool path approaching from the side parts (usually the contour cutting) is common in vertical and near vertical surface; the tool path approaching from the top part (usually a projection Milling) level and close to the level applied to surfaces. Also along the surface accuracy of each ISO line of march of the tool path. For complex surface parts, each surface has its own set of ISO lines - means that between each surface machining, the cutter knife and forced to retreat into a new set of ISO lines. So there will be many back knife. Mold makers may choose the tool path in the processing of any combination of the parts. Some problems in this approach are as follows: With the tools from one area to another area often re-positioning, complex tool path require complex back knife campaign tool. The more parts on the surface, cutting tools from one type of tool path into another tool movement when the back more. No matter how precise machine tools, because tool wear, and the former Road radius curved tool path position, these movements will generate contact mark. composite tool path in the design, testing and processing time to spend more time, but for the entire part, the surface roughness will lead to inconsistencies. In a given region than in other regions of the tool path for tool path for better surface roughness, so that programmers need to constantly adjust for the tool path for each processing parameter. CAM system according to the specified tool path and processing standards, when the composite tool path overlap, certain areas of mold may require more processing time. Mold manufacturers do not have time to be processed in accordance with standards. Better solution With intelligent CAM system processing capacity of a new tool path to resolve these issues. This tool path using a single tool path technology to intelligent application of contour parts based on the shape of the path projection processing organic combination. Interlaced spiral tool path contour cutting technology based on its part for the whole tool in the Z axis with a constant incremental feed. CAM system first analyzes the surface of the slope and shape of parts, and then use the constraint to calculate the roughness values between the contour lines in the need for spiral tool path. When the tool is still at the end of each contour cutting, it moves to the next step in any spiral contour cutting and cross cutting tool path missing light area, the move to the next contour line before cutting to the surface In addition to materials. Generated with the least number of tool retraction (if there is retracting it) with the parts match the shape of the continuous cutting tool path. Users simply specify the place and will take place staggered expect to obtain the maximum contour of the surface roughness height of the maximum slope value. CAM system to calculate the need for spiral tool path, how much and how much cut into the corner, so that the parts were constant roughness value (see the following figure: CAM system to calculate the need for spiral tool path, how much and how much cut into the corner, so that the whole Parts were constant roughness. mold manufacturer may choose the tool path to process in any combination of the parts). Staggered spiral tool path generation: direct shape-based part of the most effective tool path; No matter what the slope surface, the parts always get the same step distance with a smooth surface; limited number of back knife campaign; shortened single rail the programming time.
