Rough Machining
Makino's FF/cam Machining Process is designed to utilize the tool to its maximum cutting capabilities. Every chip is factored into
toolpath control to ensure stable, high-efficiency machining that also extends tool life.
The principle of FF Machining is to supress the rise in temprature at the cutting edge of the tool while maintaining a constant cutting load. The generation
of precisely controlled, instead of forced toolpaths, promotes extended tool life and unattended, automated operation.
Toolpaths That Maintain a Constant Machining Load Support a Stable Machining Process and Extended Tool LifeWith FF/cam, toolpath is generated specifically for continuous cutting with the tool in constant contact with the workpiece. The cutting load is
kept at a minimum and constant level while the tool is working. A wide variety off roughing strategies are available to suit any part, material, machine or cutting tool.
Remaining Stock Machining
FF/cam Automatically Searches for Flat Areas of the Workpiece Geometry and Generates Toolpath for Only Those SurfacesAreas left uncut in a previous operation are automatically detected and only those areas that require further stock removal with smaller cutter will be machined, thereby reducing milling times.
Toolpaths are automatically generated that combine orbital cutting in contour lines with helical entry where the tool does not start cutting in the Z Axis alone.
Trochoidal Machining
Places where the cutting load incrases are automatically detected in advance. Toolpath is generated that progressively shave material from the block in a circular motion.
Using this trochoidal machining funciton eliminates full-width cuts and stabalizes the machining process to enable high-speed machining with end mill's and inserted cutters.
Half Pitch Shift
For stable rough machining, the half-pitch shift function automatically generates a toolpath that shifts
the tool half a pitch from the previous path.
Using this half-pitch shift function extends tool life by preventing chipping due to a sudden change in the amount of stock being removed, which tends to occur in rough machining.
Smooth Cornering Motion
Corner radii are automatically inserted in the corner portions of the toolpath. This function not only prevents tool gouging in high-speed machining operations but also prevents tool damage due to sudden changes in the tool load.
Collission Avoidance
FF/cam checks for interference between the tool shank or holder and the workpiece. Toolpath is generated only for the portions
that can be machined with the specified tool overhang length. This function generates safe toolpaths without any holder interference, even for workpieces with deep cavities and complex geometries.
Optimal tool selection is possible since FF/cam calculates the tool overhang need for machining. FF/cam determines the shortest possible tool overhang and selects
the most efficient tool and machining conditions.
