AluminiumAluminium - a material that has a futureParticularly in the field of transportengineering massive application oflight weight materials representsthe order of the day. The goal ofsaving fuel and other energy <strong>for</strong>mscan mainly be achieved through thereduction of vehicle weights.Apart from various syntheticmaterials, the classical light metal<strong>aluminium</strong> offers the bestprerequisites <strong>for</strong> reaching thisobjective.In other application fields, too, itsnumerous favourable propertiesmake <strong>aluminium</strong> an appreciatedconstruction material <strong>for</strong> engineers.[ mill. tons]Aluminium in the automobile19992009(Prognosis EAA)Trends in the field of <strong>machining</strong>Innovative <strong>machining</strong> strategies arecharacterised by maximum cuttingspeeds and feed rates in order toobtain the highest possible metalremoval rates.Refraining from massive use ofcooling lubricant represents animportantdemand with reference tothe environmental impact.Process safety and an increase inproductivity are the prerequisites<strong>for</strong> a favourable market positionand thus competitiveness.The <strong>machining</strong> properties of<strong>aluminium</strong> are perfectly suitable <strong>for</strong>putting modern <strong>machining</strong>concepts into practice.Machining time [in h]conventionalHPC – High Per<strong>for</strong>mance CuttingTime saving withHPC <strong>machining</strong>machine down timesroughingfinishingHPC<strong>machining</strong>Prerequisites <strong>for</strong>HPC <strong>machining</strong>HSC spindle(> 25,000 rev./min)high feed rates(> 40 m/min)high acceleration(> 2.5 – 3.0 m/sec)fast CNC controls(processing speed < 3.0 ms)balanced toolsadequate cutting materialsSource: Heidelberger Druck2
