Software Demonstrations at MACH will Focus on Saving you Time

A key focus at MACH 2018 for CGTECH will be the time savings that can be achieved using the comprehensive capa- bilities of its VERICUT world leading inde- pendent machine simulation, verification and optimisation software.

The company will be running demonstra- tions at MACH with actual customer data to highlight the capabilities of VERICUT and to show how the software works and highlight the benefits it can unlock for UK engineer- ing businesses.

Managing Director, Tony Shrewsbury, said: “In today’s globally competitive environ- ment, software verification is essential to the ability of any manufacturing business to attain the goals of producing on-time, high quality parts at a minimum cost.

“VERICUT helps companies achieve these goals in five significant areas.”

The first area VERICUT focuses on is avoid- ing collisions, scrap parts and broken tools. Machine simulation within VERICUT detects collisions and near-misses between all machine tool components such as axis slides, heads, turrets, rotary tables, spin- dles, tool changers, fixtures, workpieces, cutting tools, and other user-defined objects.

‘Near-miss zones’ set up around the com- ponents check for close calls, and detect over-travel errors. Removing the risk of colli- sions avoids any gouging of the workpiece or raw material, and reduces damage to the cutting tool.

With machines modelled in a virtual world, VERICUT can speed the implementation of new CNC onto the shopfloor. As the soft- ware version of any machine tool identically reflects the static and dynamic attributes of the actual machine, any company can virtu- ally operate any machine before it is installed.

For many machine shops any capacity shortage is a serious issue. Here, VERICUT again delivers in two important ways. The first involves the relocation of any prove-outs for new parts away from the actual machine into the VERICUT virtual world. The second is the optimisation of the post processed CAM program to remove any inefficiencies.

Says Tony Shrewsbury: “Every machine shop has to introduce and prove new NC

programs at some point. For most engi- neering companies around 10 to 15 per cent of a machine tool’s spindle time is allo- cated to this. On a single 10-hour shift, working 20 days per month with 12 CNC machine tools this equates conservatively to 240 lost hours.

“Assuming the machine is charged out at a very reasonable £70 per hour, that’s

£16,800 worth of lost production time. So, the cost for a shop manually proving-out programs is over £201,000 per year.”

VERICUT also optimises the CAM program to modify feed rates to make the tool path faster and more efficient, ensuring any parts are machined safely and in the least amount of time.

This capability has recently been enhanced with the introduction of the new Force module.

Force is a physics-based optimisation method that determines the maximum reliable feed rate for a given cutting condi- tion based on four key factors: force on the cutter, spindle power, maximum

chip thickness, and maximum allowable feed rate.
