[Points to Note for Inspection of Cutting Process Parts with Tolerance Bosses (Axles)]
○ Common phenomena in cutting parts with bosses or axles include the presence of R-shaped or stepped remnants at the base of the boss, dimensional variations at the tip, middle, and base of the boss, and lack of true roundness of the boss.
[Regarding 3D Data Corrections Performed Before Cutting Process Programming]
○ For parts with large tolerances such as hole diameter, boss diameter, and plate thickness, data adjustments are made in advance to ensure that the remaining allowance for roughing is uniform.
○ When the shape is complex, coordination is carried out at the corners of the product (where machining R is applied), and adjustments are made for fitting with other parts to create the machining program.
[Regarding the Role and Characteristics of Gates in Prototype Molds]
○ Gates serve as the "entrance" for pouring molten plastic into the product shape part of the mold.
○ There are various types of gates, including side gates, jump gates, pin gates, and submarine gates.
