摘要:
The invention is a cutting machine and its method of operation. The machine contains a vise, a feed mechanism for positioning a workpiece toward the cutting position, a mechanism for detecting the front end of the workpiece, a mechanism for detecting the transfer distance of the front end of the workpiece, a mechanism acting in conjunction with the last two referenced mechanisms to reduce the feed speed of the workpiece, a mechanism to control the feed velocity of the workpiece, a mechanism to contact the first end of the workpiece, and a mechanism to halt the speed of the workpiece.

Indicator device for determining the distance between a workpiece set up in a working machine, and a tool set up in said machine. The device comprises a lower portion (2) with an underside (13) which is adapted to lie against the workpiece, and an upper portion (1) with a topside (8) against which the tool is intended to come into contact, the topside being parallel to the underside (13) of the lower portion and movable towards the underside against the efect of a resilient force. A voltage source (4) and an indicator (5) are provided. The underside (13) and the topside (8) are electrically conductive but are insulated from each other, and the indicator (5) and the voltage sorce (4) are electrically coupled so that the indicator (5) provides and indication when a circuit (16) between the topside (8) and the underside (13) is closed via the workpiece, the machine, the tool, the voltage source (4) and the indicator (5).

Disclosed is an edged tool positioning device which is fixed to the quill of a machine tool for permitting the edged tool to reach a desired X- and Y-coordinate position on a workpiece and for permitting the edged tool thus put at the desired X- and Y-coordinate position to advance a desired distance in the thickness of the workpiece in the Z-direction. Every time the device is brought in contact with at least one selected side and upper surface of the workpiece, a warning unit built in the device informs a worker of the contact by the device with the workpiece, thus permitting him to find a start position and measure a desired distance in each direction.

A rotatably indexable tool-programming drum for use in a machine tool having a rectilinearly reciprocal tool carrying assembly movable exteriorly over the length of the drum which carries one or more removable strip members having plural outwardly projecting and selectively positioned block members therealong, one of which has an end surface engageable with stop means on the tool carrying assembly for limiting the stroke of the assembly; the second of which has an outer cam surface engageable with follower means on the assembly and actuatable for changing the rate of rectilinear movement of the assembly from rapid traverse to tool feed rate, and a third of which carries adjustable projections engageable with means actuated thereby for regulating the rotational speed of a workpiece in the machine tool and the feed rate of a work tool engaged with the workpiece; each strip member being removable from the drum for presetting of the block members in predetermined relative positions remotely of the machine tool as determined by a predetermined operating program and movements for an associated work engaging tool.
摘要:
A device strips circular areas of insulation to expose the flat conductors in flexible printed circuits, flat electrical cables, multilayer circuit boards and the like, to permit making electrical connections thereto. The basic principle of operation resembles that of an end mill or drilling machine. The new machine employs rotating cutters of novel shape which cut more readily through insulating films and sheets than through metals such as copper, and the machine has a precision depth stop. Both features prevent cutting through the thin foil conductors. The depth stop may be set so that the cutter penetrates the foil by a small fraction of its thickness, exposing a clean metal surface for soldering. The bottom of the cut is visible during the cutting operation.
