CMM Measurement

Quality first

Our 3D inspec­tion soft­ware, Metrolog, is by far the most com­pre­hen­sive fully fea­tured soft­ware able to run on all exis­tent Coordinate Measuring Machines (CMM) on the mar­ket. CMM have been the main­stay of mea­sure­ment in the metal cut­ting, form­ing and plas­tic mold­ing indus­tries since decades. Precision com­po­nents of watches to sheet metal cas­ing of domes­tic appli­ances are inspected with CMM. These machines are used in metrol­ogy insti­tutes and cal­i­bra­tion lab­o­ra­to­ries as well as a vari­ety of indus­trial appli­ca­tions. Ultra-​high accu­racy CMMs are used in areas such as auto­mo­tive, aero­space, mechan­i­cal engi­neer­ing and wher­ever spe­cial geome­tries must be mea­sured with the utmost precision.

The intro­duc­tion of inno­va­tions and new tech­nolo­gies are con­stantly chang­ing the indus­trial land­scape, trans­form­ing the way we see and per­form three-​dimensional qual­ity con­trol. Despite new sen­sor tech­nolo­gies free of the CMM frame, pro­fes­sion­als face numer­ous chal­lenges: there are extra lay­ers of poten­tial mea­sure­ment uncer­tainty, tol­er­ances are becom­ing tighter, advanced man­u­fac­tur­ing requires a much bet­ter oper­a­tor under­stand­ing of CMM strate­gies.  Some talk about more afford­able alter­na­tives, but is the alter­na­tive where high accu­racy is a prerequisite?

Transform your CMM into a valu­able asset

CMMs are pop­u­lar for their unique abil­ity to mea­sure tight tol­er­ances with a high level of accu­racy. However, despite being the most accu­rate metrol­ogy equip­ment, CMM can be also source of 3D metrol­ogy bot­tle­neck issues. Let us explain why.

  • First, CMM is fixed lab­o­ra­tory equip­ment adapted to cer­tain sizes of parts. It is also bet­ter suited for rather del­i­cate inspec­tions, com­plex geome­tries or high-​tolerance features.
  • It is a highly com­plex metrol­ogy instru­ment requir­ing highly skilled and expe­ri­enced operators.
  • Conventional com­mon CMM are not well rated for their through­put, but lat­est CMM mod­els can please mass pro­duc­tion man­u­fac­tur­ers seek­ing reduced mea­sur­ing cycle times for improved pro­duc­tion performance.
  • The built-​in soft­ware pro­vided by the CMM man­u­fac­tur­ers usu­ally allows basic mea­sur­ing rou­tines with very lim­ited capabilities.
  • Besides this, CMM are sen­si­tive to envi­ron­men­tal para­me­ters influ­enc­ing results con­sis­tency and repeata­bil­ity (tem­per­a­ture, floor vibration).
  • Finally yet impor­tantly, CMM require reg­u­lar main­te­nance and cal­i­bra­tion, and in order to obtain cus­tomer approval for man­u­fac­tured parts, a cal­i­bra­tion cer­tifi­cate, among oth­ers, is manda­tory to guar­an­tee com­pli­ant qual­ity control.

Purchase of a new CMM

You are in a process of select­ing a new CMM that fits best or bet­ter to your require­ments, we know it is not an easy task. This implies some think­ing and research, but you do not have to do it alone. Together with lead­ing equip­ment man­u­fac­tur­ers who are sus­tain­able part­ners, Metrologic Group can pro­vide most com­mon brands of CMM — equipped with Metrolog and Silma!

Improvement of CMM capacity

You have already a great CMM, but you would like to mod­ern­ize it and restore its full per­for­mance, our experts can advise. A retro­fit or a soft­ware upgrade can be a cost-​effective way to increase CMM capac­ity. CMMs are built to last, we can help you refresh the system!

Metrolog user already

Your CMM works fine with Metrolog, but some errors still occur, let us dis­cuss about it. Besides need for cal­i­bra­tion or envi­ron­men­tal issues, oper­a­tors can also induce errors. If you are con­cerned about the skills of your pro­gram­mers and oper­a­tors, Metrologic Group offers hands-​on train­ing, not which but­ton to press but the how to grow skills on a solid 3D metrol­ogy foundation.
