Jika burr berubah seiring kecepatan, periksa stabilitas tegangan dan pelumasan.<\/p><h3 class=\"wp-block-heading\" id=\"8ba41720-1684-482f-a3a7-df1d40da1b63\">Q: Persentase celah pisau slitting (clearance) berapa yang harus saya gunakan sebagai awal?<\/h3><p>A: Gunakan rentang awal berdasarkan material (bukan % tunggal yang tetap). Mulailah dari tengah rentang, jalankan strip verifikasi singkat, lalu sesuaikan dalam inkremen kecil sambil mencatat tinggi burr.<\/p><h3 class=\"wp-block-heading\" id=\"b963eebc-4de6-471e-9802-020da0b5a18c\">Q: Apakah tumpang tindih vertikal (vertical overlap) yang lebih besar selalu mengurangi burr?<\/h3><p>A: Tidak. Tumpang tindih berlebihan dapat meningkatkan burr dan merusak tepi pisau. Perlakukan tumpang tindih sebagai variabel terkontrol dan kurangi jika burr meningkat seiring bertambahnya kedalaman.<\/p><h3 class=\"wp-block-heading\" id=\"b1eb926a-c52e-4179-b719-f03deaf70a2c\">Q: Bagaimana cara mengukur tinggi burr secara konsisten?<\/h3><p>A: Gunakan metode yang ditentukan (mikroskop\/optik\/profilometer), lokasi pengambilan sampel yang tetap, dan templat pencatatan yang dapat diulang. Laporkan tinggi burr sebagai % dari ketebalan jika gambar teknis mengizinkan.<\/p><h3 class=\"wp-block-heading\" id=\"448aabe9-153f-4490-8d49-03e3c2c35698\">Q: Mengapa burr lebih buruk pada satu tepi potongan daripada tepi lainnya?<\/h3><p>A: Pola tersebut sering kali menunjukkan masalah keselarasan (alignment), runout, atau masalah pada susunan\/spacer yang menciptakan celah tidak merata. Periksa kembali sejajarnya poros (arbor), dudukan pisau, dan akurasi spacer.<\/p><h3 class=\"wp-block-heading\" id=\"93ae3aa5-2ee2-4ba4-ab57-d7abe04a0603\">Q: Seberapa sering pisau pemotong longitudinal (slitter knives) harus diperiksa dan mengasah ulang (reground)?<\/h3><p>A: Periksa sesuai jadwal yang terikat pada toleransi burr dan tingkat keparahan material Anda, menggunakan pembesaran 30\u201350\u00d7.
