Check that first panel again before running the batch.\n  <\/div>\n\n<\/section>\n\n\n<section class=\"qc-section\" id=\"process\">\n\n  <h2>How to Get the Holes Back on Target<\/h2>\n\n  <h3>1. Go back to the drawing datum<\/h3>\n\n  <p>\n    Find out what the hole positions are measured from. It could be the raw panel edge, finished edge, edge-banded size, groove center or another feature. A wrong reference can give you perfectly repeatable holes in the wrong place.\n  <\/p>\n\n  <h3>2. Make sure the panel cannot move<\/h3>\n\n  <p>\n    Clean the table, check the spoilboard, use the correct vacuum zones and make panel positioning repeatable. Narrow parts and drilling close to an edge need enough support around the drilling area.\n  <\/p>\n\n  <h3>3. Check the drill and holder<\/h3>\n\n  <p>\n    Look at the cutting edge, shank, collet cleanliness, clamping and runout. If a drill is worn or the collet is dirty, fix that before touching servo or controller parameters.\n  <\/p>\n\n  <h3>4. Match the drilling method to the hole<\/h3>\n\n  <p>\n    Spindle drilling works well when the hole and tool suit the job. Interpolation gives more diameter flexibility but takes more cycle time. If one furniture panel contains many repeated holes, a drill bank or dedicated drilling unit can be more efficient than changing router tools one by one.\n  <\/p>\n\n  <h3>5. Set the cutting condition around the real material<\/h3>\n\n  <p>\n    MDF, plywood, melamine, particle board, acrylic and composites do not behave the same way. Start from the drill manufacturer&#8217;s data, then look at chips, heat, noise, hole edge, diameter and repeatability on the material you actually use.\n  <\/p>\n\n  <h3>6. Check the real panel thickness and Z reference<\/h3>\n\n  <p>\n    Do not assume every nominal 18 mm board is identical. Check the actual panel, spoilboard and Z reference. Blind hinge and connector holes should be checked for depth before production continues.\n  <\/p>\n\n  <h3>7. Approve the first panel as a finished part<\/h3>\n\n  <p>\n    Measure the important holes from the correct datum, then install the hardware or assemble the mating panels. If a correction is needed, record the program, drill, material and change so the result can be repeated on the next shift.\n  <\/p>\n\n  <div class=\"qc-callout qc-callout--warning\">\n    <span class=\"qc-callout-title\">Do not approve the process from one good hole<\/span>\n    Check several positions on the actual panel and make sure the hardware or mating part fits. One clean hole in the middle of the sheet does not prove the whole drilling process is right.\n  <\/div>\n\n<\/section>\n\n\n<section class=\"qc-section\" id=\"machine-choice\">\n\n  <h2>When Is a CNC Router Enough\u2014and When Does the Machine Type Need to Change?<\/h2>\n\n  <p>\n    Start with two things: <strong>which faces need holes<\/strong> and <strong>how much of the normal cycle is drilling<\/strong>.

A CNC router can handle cabinet drilling when the hole directions, drill, panel holding, datum and program suit the job.
