Without considering the preparation of a machine detailed below, the working process of a CNC drill can be described as the following. Spindles securing the chucks, drill bits, and other movable parts of a machine are activated by an operator through the control panel. Then, following the CAD/CAM file, a drill adjusts speed, fed rate, and the position of its spindles while cutting holes of appropriate depths and diameters. 

After the machining is over, parts manufactured are checked for compliance, and adjustments are made, if necessary. Sometimes the manual change of tools in spindles is required if the pre-installed, in a tool changer, drill bits are not enough for all the types of holes needed in the design.

Such constructing decisions enable the simple arrangement of furniture with basic instruments. An example of the CNC machine is shown in the image below.[/et_pb_text][et_pb_image src=”http://ecoreprap.com/wp-content/uploads/2022/01/cnc-drilling-dowel-inserting.jpg” alt=”cnc-drilling-dowel-inserting” title_text=”cnc-drilling-dowel-inserting” align=”center” _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][/et_pb_image][et_pb_text _builder_version=”4.16″ _module_preset=”default” text_font=”Lato||||||||” text_text_color=”#292929″ text_font_size=”17px” custom_margin=”||18px|||” global_colors_info=”{}”]

From the perspective of programming, a CNC drilling & dowel insertion machine to be operated correctly should be prepared according to the same steps as any other machine.

Such stages are detailed further, along with some additional information enabling to deepen more into programming, particularly a CNC drilling & dowel insertion machine.
