Simple programming and comprehensive tool management
The intuitive operation manager has a simple tree structure displaying the machining operations and the selected tools from the comprehensive tool library. Based on piece and tooling material, many machining parameters are calculated automatically, including feeds, speeds, stepover and depth of cut. A highly graphical interface guides the user through the machining parameters, cutting conditions and holders for the selected tooling. Multiple origins enable the data to be quickly orientated around any datum or set-up for multi-axis indexing.
Center drilling, drilling, tapping, reaming, boring, helical milling, thread milling and mill drill cycles give the user a wide choice of operations to cover any combination of hole type. Selection of diameters and depths directly from the model makes it easy to enter drilling parameters and eliminate the possibility of MDI errors. Optimisation of the toolpath movement ensures the shortest distance for tool travel and reduces cycle times offering maximum productivity.
Full range of drilling cycles
The profiling operations give a choice of machining direction, circular or direct approach, and the ability to cut down to a depth with a sequence of profiling moves. Cutter radius compensation capability provides practical CNC code for use on the shop floor. When the cutter cannot machine tight internal radii, the system will automatically create residual stock geometry (defined by the previous tool) and enable re-machining with a smaller tool. Spiral or zigzag face milling operations, with internal island nesting provide a choice of methods to clean up planar faces. Milling by successive passes allows the user to mill a profile and start away from the material, gradually moving inwards using a stepover parameter.
Profile and face machining operations
VISI allows spiral and zig-zag pocketing operations with multi depth islands nesting including the ability to define draft angles and base radii for the pocket and island walls. Individual control for the bottom and side tooling oversise plus options for automatic island face milling provide optimum flexibility to suit individual machining requirements. For open sided pockets the user can identify the open faces and the cutter will then automatically start outside of the feature and move across the open edge to remove any residual stock.
Open and closed pocket machining
Extrusion, revolution or sweeping a 2D profile along another 2D curve provide the programmer with the ability to produce simple 3D toolpaths without the need of a full 3D machining system or indeed the need to create a 3D model. Internal and external thread milling, helicoidal milling and fillet / chamfer machining for sharp edges offers maximum toolpath flexibility.
2.5 axis toolpaths for simple 3D forms
By identifying clamps and fixtures, the system will automatically avoid these using the shortest route during machining operations. Obstacle management ensures collision avoidance, and helps to reduce the cycle time on the machine by eliminating unnecessary Z retract moves. Graphical toolpath verification enables the user to check the complete cycle of operations. Simulation of the tool path shows the expected surface finish, the amount of material being removed by each operation and a warning of any potential collisions.
