Ren­ishaw bets big with new ad­di­tive man­u­fac­tur­ing sys­tem

Ren­ishaw, a world leader in pre­ci­sion en­gi­neer­ing tech­nolo­gies, has launched new range of metrol­ogy and ad­di­tive man­u­fac­tur­ing equip­ment. The new prod­uct is de­signed to meet the re­quire­ments of the ad­vanced man­u­fac­tur­ing sec­tor in In­dia; from the need to pro­duce parts with in­creas­ing com­plex­ity and tighter tol­er­ances, to the drive to re­duce costs, to in­crease speed of op­er­a­tion and the re­quire­ment to im­prove the ease-of-use for new tech­nol­ogy.

Ren­ishaw has been trad­ing in In­dia since 1983 and it em­ploys 350 highly skilled peo­ple across the coun­try, in­clud­ing a wholly-owned sub­sidiary in Ban­ga­lore and a large fa­cil­ity in Pune. Many of its em­ploy­ees in In­dia di­rectly con­trib­ute to the R&D and man­u­fac­ture of its ex­cit­ing mea­sure­ment and metal 3D print­ing tech­nolo­gies.

In June 2016 Ren­ishaw opened an Ad­di­tive Man­u­fac­tur­ing So­lu­tions Cen­tre at its Pune site, which aims to in­crease the adop­tion of metal 3D print­ing tech­nolo­gies by In­dian man­u­fac­tur­ers. Re­cently the com­pany in­tro­duced the RenAM 500M ad­di­tive man­u­fac­tur­ing sys­tem, which has been fully de­signed to be used for se­ri­alised pro­duc­tion of com­plex metal com­po­nents di­rectly from CAD us­ing metal pow­der fu­sion tech­nol­ogy. High­lights of the sys­tem in­clude a Ren­ishaw de­signed and en­gi­neered op­ti­cal sys­tem with dy­namic fo­cussing, au­to­mated pow­der siev­ing and re­cir­cu­la­tion, a 500 W yt­ter­bium fi­bre laser and patented high ca­pac­ity dual fil­ter Safe Change sys­tem.

As de­mands on com­po­nent tol­er­ances in­crease, man­u­fac­tur­ers are now re­quired to con­sider all er­ror sources from the machines pro­duc­ing parts; an­gu­lar er­rors as well as lin­ear and straight­ness er­rors. Ren­ishaw also launched its new XM-60 multi-axis cal­i­bra­tor re­cently, which is ca­pa­ble of mea­sur­ing all 6 de­grees of free­dom from a sin­gle set-up, in any ori­en­ta­tion for lin­ear axes. It of­fers sig­nif­i­cant im­prove­ment in sim­plic­ity and time sav­ing over con­ven­tional laser mea­sure­ment tech­niques. The XM-60 uses the XC-80 en­vi­ron­men­tal com­pen­sator to cor­rect for en­vi­ron­men­tal con­di­tions.

The com­pany’s new vi­sion mea­sure­ment probe (RVP) for use with the REVO-2, 5-axis mea­sure­ment sys­tem on co­or­di­nate mea­sur­ing machines. Thin sheet metal parts, com­po­nents with large num­bers of holes (as small as 0.5 mm), and parts which are not suited to tac­tile mea­sure­ment can now be fully in­spected with the RVP sys­tem. The new probe in­creases the multi-sen­sor ca­pa­bil­ity of REVO-2 by adding non-con­tact in­spec­tion to the ex­ist­ing touch-trig­ger, high-speed tac­tile scan­ning and sur­face fin­ish mea­sure­ment ca­pa­bil­ity of the sys­tem.

In the re­cently con­cluded IMTEX 2017, Ren­ishaw show­cased its new high pro­duc­tiv­ity machining cell con­cept which demon­strates how the abil­ity to mon­i­tor key process in­puts, an­a­lyse data and continuously im­prove man­u­fac­tur­ing pro­cesses fa­cil­i­tates in­creased pro­duc­tiv­ity and higher ac­cu­racy. The com­pany be­lieves that sim­ply mea­sur­ing the out­put of a man­u­fac­tur­ing process us­ing ‘tail­gate’ in­spec­tion is not enough and, more of­ten, too late to con­trol all the vari­abil­ity in that process. It is crit­i­cal that checks and mea­sure­ments are also made be­fore, dur­ing and im­me­di­ately af­ter machining to con­trol both com­mon-cause and spe­cial-cause vari­a­tion.

Ren­ishaw also demon­strated new MODUS 2 metrol­ogy soft­ware suite which sim­pli­fies the pro­gram­ming of CMMs, plus Ren­ishaw’s full suite of ma­chine tool probes, cal­i­bra­tion prod­ucts, metrol­ogy fix­tures, styli and po­si­tion en­coders, in­clud­ing the new VIONiC dig­i­tal en­coder and the Queen’s Award win­ning RESOLUTE ab­so­lute en­coder.
