Abstract: Spaced cutting tools, each having a plurality of linear axes and a rotational axis, are supported with a conveyor carrying successive parts past the tools. The tools include positioning motors and are positioned by a computer driven system including a controller and a tool program for positioning the tools to sequentially cut each part. Separate computer boards each include a memory unit and a CPU for coupling to individual positioning motors for each tool. The controller downloads the program for particular axes to the board for the tools. A positioning sensor is coupled to each tool axes and connected to the computer input for monitoring each tool position. All tools are simultaneously positioned using an initial fast constant speed feed followed by a varying slow speed, with a closed loop control, within a fixed time period.

Abstract: A woodworking machine has a series of stations spaced along a conveyor having a clamp support for holding flat wood parts and passing the edges through the stations which include cope stations as well as others. The coping stations have a tool unit with a stack of tools mounted on a common spindle. The tools in each stack at the several stations are interrelated such that the cuts of the individual tools can be combined to form different final profiles in a wood part moving through the several stations. The particular cuts in the profile line are analyzed and interrelated to define basic cuts which can be combined to form the final profiles. One tool of each tool stack provides a particular cut, and by precise positioning of the individual tools, the combination of sequential cuts provide the final profile. Each tool may form a complete cut, may overlap a previous cut to form a continuation of such previous cut or may form a cut which includes only a portion of its cutting face.
