Fabrication of Multi - Diameter Hole Attachment for Upvc Routing Machine

Abstract

Routing is the process to making handle holes in one height of each panel to fit handles in it. most of the routing machine consist of y and z direction adjustment for restricting head moment in order to make rectangular hole in profile, while following this process for routing it initially takes around 20min for adjustment of restriction bar according to required hole size, also in case of any other hole apart from rectangle hole is not possible with restriction used. When circular multi-diameter holes needed, in that case we have to mark the hole shape on profile and make hole free hand, resulting in poor finish and waste of material. Hence we introduced a stepped bar which we welded on the moving tool head and

added a required hole shape guide plate so the we can push the welded bar attached to moving tool head in the guide plate hole and the moving tool head will copy same shape resulting accurate hole on profile including circular multi-diameter hole with greater finish and eliminating the setting/adjusting time needed for routing process.
