Embodiment Construction

[0015] Exemplary embodiments of the present invention are given herein with reference to the accompanying drawings. Here, the same reference numerals denote the same components.

[0016] A machine may be configured to perform work operations at a job site. Examples of machines may include cold-grade mills, on-highway and off-highway vehicles, construction equipment, and earth moving equipment. While the teachings of the present invention are not limited to a particular type of machine, the exemplary machine 100 (cold temperer) is Figure 1-3 shown in and described below to illustrate the teachings of the present invention.

[0017] Exemplary machines 100 , such as milling machines or cold planers, may be configured to remove, mix, or reclaim material from asphalt-containing surfaces, concrete or tarmac roads, and other surfaces. The cold planer 100 may include a frame 102, a support apparatus 112, a plurality of ground engaging units 114, and a tool 116 (eg, a rotatable gri...

Abstract

A milling machine is provided including: a frame; a plurality of ground engaging units; a plurality of vertically adjustable legs, the plurality of vertically adjustable legs comprising a front leg and a rear leg; a rotatable mill configured to mill a surface; a user interface configured to receive a milling grade depth and a cut-transition factor; a speed sensor configured to provide a ground speed of the milling machine; a vertical position sensor; and a controller coupled to the speed sensor, the vertical position sensor, and the user interface, the controller configured to lower a height of the rotatable mill to the milling grade depth by incrementally adjusting a length of at least one of the plurality of vertically adjustable legs according to the cut-transition factor, the speed sensor, and the vertical position sensor.

Description

technical field [0001] Embodiments of the present invention relate to machines for the treatment of road surfaces, and more particularly to road grading machines for road surface manipulation. Background technique [0002] Road milling machines, also known as cold graders, may be configured to remove, mix or recover material from asphalt-containing surfaces, concrete or asphalt roads, or other surfaces using rotatable graders mounted on a frame. The frame may be mounted on tracks or wheels that support and transport the machine along the road surface. [0003] Typically, cold planers may also include a plurality of lift members positioned near the front and rear of the frame. The lift member is adjustable between extended and retracted positions to control the depth and shape of the cut by raising or lowering the frame and rotatable leveling tool. [0004] Road surfaces are typically used after the road has been milled by a milling machine. The absence of a smooth transit...
