Reverse engineering merupakan inovasi dalam pembuatan produk. Produk yang telah ada dianalisis untuk dilakukan pengembangan produk atau meningkatkan performa. Penelitian ini difokuskan pada penerapan metode reverse engineering untuk membuat toolpost, mengingat kebutuhan suku cadang toolpost mesin bubut konvensional masih bergantung pada impor dan seringkali tidak tersedia dipasaran karena pabrikan sudah tidak ada. Tahapan yang dilakukan meliputi pengumpulan informasi produk, analisis fitur fungsional, pengukuran dan pemodelan toolpost serta analisis keterbuatan melalui simulasi pengecoran. Simulasi pengecoran ini bertujuan untuk mengidentifikasi potensi cacat yang akan terjadi, sebelum desain toolpost akan diwujudkan dalam produk jadi. Hasil simulasi menunjukkan total cacat porositas sebesar 2% dengan lokasi cacat yaitu pada area gating system dan area lubang pada toolpost. Meskipun terdapat cacat, persentase dan lokasi cacat tersebut dapat dianggap tidak akan mempengaruhi keberfungsian dari toolpost. Waktu tuang optimal yaitu 2,38 detik dan waktu pendinginan yaitu 201,3 detik untuk mencegah terjadinya retak dan deformasi.
