Kertas kajian ini mengemukakan algoritma interpolasi CNC bagi lengkok parametrik umum 2D. Interpolasi yang dikemukakan ini menggunakan teknik rujukan-dedenyut ataupun teknik langkah-tambahan. Algoritma ini berasaskan kepada pencarian secara berterusan garisan-lingkungan yang bersilang dengan lengkok parametrik. Setelah garisan-lingkungan dikenalpasti, kawasan jarak-terdekat digunakan untuk memilih titik interpolasi tanpa melaksanakan pengiraan. Simulasi komputer secara real-time menunjukkan bahawa interpolasi yang dikemukakan ini telah meningkatkan halaju maksimum yang dibenarkan dan pada waktu yang sama mengekalkan kejituan yang tinggi. Kata kunci: interpolator; CNC; rujukan-dedenyut; peralatan mesin This paper proposes an efficient CNC interpolation algorithm for general 2D parametric curves. The proposed interpolator uses reference-pulse or incremental step technique. The algorithm is based upon finding the successive enclosing-lines that the parametric curve intersects. Once the intersected line is identified, the pre-defined closest distance region is used to select the interpolating point without resorting to calculation. Real-time computer simulations indicate that the proposed algorithm increases maximum allowable velocity while still maintaining high precision. Key words: interpolators, computerized numerical control (CNC), reference pulse, machine tools
