GTMA SUPPLIERS AT MACH

With VERICUT Reviewer shopfloor personnel, suppliers, customers, and other production

engineers can view animations of the

CNC machining process. It is a stand-alone viewer that does not

use a license that can play forward and backward while removing

and replacing material. New for MACH, the Reviewer files will also

be able to operate on an iPad. Other key positives:

Integration with CAM CNC Programming: As an independent

system, VERICUT can run standalone and simulate the CNC

process driven by post-processed NC code. However, in practice,

most manufacturing companies use a CAM system to create CNC

part programs. VERICUT can be integrated with all leading CAM

systems including Dassault Systemes CATIA, Siemens PLM NX,

Delcam PowerMill and FeatureCAM, Vero EdgeCAM, DP

Technologies Esprit, CNC Software MasterCAM and Open Mind

HyperMill.

Integration with cutting tool suppliers and Tool Management

Systems: As with all software programs the accuracy of the data

input will directly affect the output. So, an accurate model of the

cutting tool and holder is required for the effective and accurate

simulation of the machining process. Leading cutting tool manufacturers,

such as Sandvik, Kennametal and Iscar, now make 3D

solid model data available to users and VERICUT has tools to read

in this model data for use in the simulation process. VERICUT also

interfaces with tool management systems such as TDM Systems

and WinTool for access to databases holding cutting tool

information.

Simulation of all types and machine tool brands: CGTech has

worked with end users and machine tool manufacturers and distributors to create

accurate and effective Virtual Machine Tool configurations. These range from

simple 3-axis milling machines and

multi-axis machining centres to simple 2-axis lathes, water jet and

laser cutting, and machining/polishing robots. VERICUT simulates

every machine tool brand.

Other Products: With the growth of the various additive manufacturing processes

CGTech has developed programming and simulation of the CNC processes

used in this technology area, including

automated composites fibre placement and tape laying. The automated drilling and fastening machines used for the production

of

aero-structure components are also supported by VERICUT Drilling

& Fastening (VDAF). It allows the user to visualise and simulate

CNC drilling and fastening machines using the same NC program

code that will be run on the machine.

GTMA

VERICUT machine simulation, verification and

optimisation software is

at the heart of CNC

manufacturing.

New for MACH - the

VERICUT Reviewer files

can also operate on

an iPad.

HEIDENHAIN (GB)

HEIDENHAIN's innovative CNC system

functionality for chatter control has

reinforced the company's TNC control

as world-leading technology and can

be seen at MACH.

The enhancement is part of the new suite

of Dynamic Efficiency and Dynamic

Precision developments that allow TNC

system users to achieve:

• Faster, more stable and predictable

machining

• 20-25 per cent improvements in heavy

machining metal removal and

• Higher levels of surface finish and accuracy.

Dynamic Efficiency combines effective

control routines with intelligent machining

strategies while exploiting the machine's full

potential and limiting mechanical

loads/process-induced vibrations.

Active chatter control (ACC) reduces the

occurrence of chatter to permit improved

infeed rates by applying damping to raise the

feedrate threshold at which chatter will arise.

ACC detects chatter through the measuring

signals of the feed drives then uses the

drives to withdraw energy from the vibration. TNC users can define when ACC will

be used; separate parameters can be

selected for each tool.

ACC also improves tool life as well as having a positive effect

on the machine main

spindle, guideways, ballscrews and

bearings.

Dynamic Efficiency also embraces functionality for adaptive feed control

- to optimise

feed rates depending on machining conditions - and trochoidal

milling, which accelerates the roughing

of slots and pockets.
