NCG CAM Solutions is due to release NCG CAM V10, which features a number of improvements said to be beneficial for large parts, such as large automotive components.

NCG CAM V10 includes enhanced multi-tasking capabilities, a feature for roughing with solid carbide cutters, an algorithm for rest roughing and faster rest finishing.

The five-axis module now also features machine tool simulation.

NCG CAM V10 is available as 32-bit and 64-bit versions.

Parallel processing in NCG CAM V10 further improves the use of central processing units (CPUs) by speeding up the calculation time, thus enhancing the multi-threading capabilities.

Almost all PCs today are dual core, if not quad core, and therefore support parallel processing.

This means that a PC could typically support between two and eight CPUs in one form or another, although the user could have 16 or more CPUs on a high-end PC.

NCG CAM now utilises this parallel processing facility.

For example, when calculating rest finishing passes, rather than using a single processor, NCG CAM will spread the calculation among all the available processors.

Rest finishing is said to be up to 300 per cent faster with four processor PCs and up to 400 per cent faster with eight processor PCs.

Adaptive area clearance is a new feature added to the basic module of NCG CAM V10.

Adaptive area clearance eliminates full-width cuts using a concept similar to trochoidal milling.

This cutting technique is targeted at high-speed machining with solid carbide cutters.

It provides the ability to safely cut using the full length of the flute at the optimum cutting speed for the material and the part.

Tool wear is spread evenly, cutting more on the flute than the bottom of the cutter, reducing deflection and the potential for vibration by maintaining a constant load on the cutter.

The technique is particularly suitable for cutting hard materials and also some electrode manufacturing.

The cycle automatically adjusts the toolpath for efficient and safe machining, improving cutting conditions and enabling more consistent and possibly higher machining speeds to be maintained.

As well as improving tooling life, adaptive area clearance can reduce machining time by an average of 25 per cent over conventional roughing as the machine uses the full flute length of the cutting tool and the machine runs at the optimum speed without exceeding its limits at an isolated point.

The linking order is very important, so the linking is done at the same time as the passes are calculated.

After each level has been cleared using all of the flute length, additional passes can be made to reduce the size of the terraces on the 3D form.

These additional passes will be either profile or clearance passes as required, depending on the material remaining or the shape of the part.

A new, optimised algorithm for calculating the rest roughing is now included in the basic module of NCG CAM V10.

This new algorithm gives a speed improvement of more than four times across a wide range of example parts.

Speed improvements are greater still on some larger jobs.

Recent improvements to NCG CAM have made the rest finishing complete in 50 per cent of the time, when supporting tool holders.

Combined with the use of parallel processing, the speed increase is said to be even greater.

A 10x speed increase can be seen, when compared with NCG CAM V9 running on a eight-processor PC, according to the company.

Machine tool simulation has been added to the five-axis add-on module and is now included as standard.

The machine tool simulation allows the user to simulate the machine movement.

This is generally important for five-axis toolpaths, where it is often difficult to visualise the real position of the machine when animating the toolpath.

By running the toolpath through the machine simulation, the user can be sure that there will be no collision between the machine head and the bed/table of the machine.

The user can control the simulation speed and zoom in and out.

Should there be a collision, it will be highlighted graphically and a dialogue is displayed to inform the user.

First of all, the basic machine needs to be modelled up.

The simulation will then check that the head of the machine will not collide with the workpiece or the bed of the machine tool.

The machine tool simulation is also able to simulate the stock being removed pass by pass.
