Area Clearance Roughing

NCG CAM’s automatic roughing of surface data is suitable for all types of 2D or 3D forms, creating an optimised, smooth cutting motion for high speed machining (HSM) while maintaining part accuracy, cutting tool life and machine tool life. All cutters and tool-holders are collision protected to maximise efficiency and stock model visualisation of the machined part is available at every stage of the manufacturing process.

Core Roughing

NCG CAM has an additional routine for roughing which is ideal for core forms, where the machinist wants to rough away the material by machining from the outside, whilst maintaining climb milling. All toolpaths start in fresh-air at the given Z-depth, and work into the middle.

Raster Roughing & Zig-Zag Roughing

Zig-zag roughing in NCG CAM will take linear cuts across the job at fixed Z levels, similar to area clearance or core roughing passes. As these passes are linear, there is far less data involved and fewer changes of machine directions. At each level a profile pass is performed to remove the cusps around the parts profile at that level, before moving down to the next Z-level.

Stock Models

Stock models can be created from one or more toolpaths, which can be 3, 3+2 or 5 axis, or a combination. Stock models can be used for the visualisation of the machined part on the screen, eliminating any costly test cutting.

Horizontal Area & Horizontal Core Machining

Horizontal area passes are used to finish machine flat surfaces more efficiently by using flat bottom cutters. Horizontal area passes are aimed towards cavities, while horizontal core passes start off the block and machine in from the side making them more suitable for core forms, whilst extending tool life.

Spiral Machining

This creates an archimedean spiral toolpath from a given focal point, generating a constant contact as it machines within a given boundary.

Radial Machining

Similar to spiral machining, radial machining also starts from a focal point, providing the user with the ability to create radial passes. Some extra options include the ability to stop short of the centre where the radial passes become very dense.

3D Constant Offset Machining

The constant offset machining strategy is used for maintaining a constant equidistant step-over from one tool pass to the next, irrespective of the slope angle of the part.

Pencil Milling

The pencil milling routine is to finish corners which might otherwise have cusp marks left from previous machining operations.

Parallel Pencil Milling

Parallel pencil milling is an extension of pencil milling, in that the user can determine the number and step-over of multiple-passes either side of the pencil toolpath.

Boundary Machining

Boundary machining, machines along an open or closed boundary profile. A negative machining thickness can be used to machine at constant depth below the surface being machined and can be used in conjunction with cutter contact angles.

True Surface Machining

NCG CAM machines using triangulations as standard, which are quick to calculate and check against for gouge free machining. True surface machining is optional for users to select, should they wish. Machining the surfaces spaces the points in the NC Tape file more uniformly, giving a better / smoother machine movement on some machine tools. However, the calculations to ensure the machining is gouge free will take longer in most cases.

The better the surface finish means less hand polishing, which saves time and money, it also reduces any mis-match / flash caused by polishing rolling/belling corners.

Surface Analysis

The curvature function allows the user to quickly find out what the smallest radii is on the part to aid cutter selection. Internal and external radii are filterable and the radii range is user definable. For quick identification this is done graphically using a colour overlay to the surfaces and the cursor tool tip provides an accurate size.

Combined Passes – Waterline & Constant Stepover

The curvature function allows the user to quickly find out what the smallest radii is on the part to aid cutter selection. Internal and external radii are filterable and the radii range is user definable. For quick identification this is done graphically using a colour overlay to the surfaces and the cursor tool tip provides an accurate size.

3+2 Axis Machining

3+2 multi-axis machining has an easy to use graphical interface, including being able to snap to the surface normal for machining.

Rest Areas Options

NCG CAM has rest area machining options on all the finishing routines, such as waterline, raster, spiral, radial, constant step-over, parallel pencil passes, corner offset passes, morphed and boundary passes.
