var fDesc=new Array(); fDesc[0] = "G-Wiizard's machining calculator is designed to help you determine the best feeds and speeds for particular machining operations. Getting the best feeds and speeds is one of the most important steps to ensure maximum material removal rates, best surface finishes, and better tool life. The Feeds and Speeds calculator considers many additional variables that simple look up tables and the SFM and chip load math every machinist knows by heart don't. Considerations such as radial chip thinning, and when it's better to climb versus conventional mill are very important to getting the best results."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
