.... This causes welding to the tool during the machining operation and consequent galling, smearing, and chipping of the machined surface, along with rapid destruction of the cutting tool. Titanium has a lower elastic modulus than steel and superalloys and thus has more “springiness” than these metals...

... poor finish, more rapid tool wear, and loss of tolerances. Reduced wheel speeds, as contrasted with those employed with steel, aid in grinding performance. In surface grinding, for example, 279 sm 2 /min (3000 sft 2 /min) has been found to cause minimum surface stresses and distortion. The basic...

... is shown in Fig. 12 . The benefits of these differences, improved hardness uniformity and grindability, have led to the increasing use of P/M tool steels. Low-alloy steels and superalloys are other examples where rapid cooling benefits are exploited. New alloys continue to be developed, often...

... of the as-deposited part. Machining times are reduced by as much as 30%. In addition, there are no expensive dies or tools required. Finally, the part lead times are much shorter: 12 to 18 months for forgings versus only several months for laser-formed preforms. This process can also be used to conduct local repairs...
