Abstract: A machine tool has a pallet transfer system comprising a rotary deck having a pair of pallets oppositely disposed about a vertical rotary transfer axis, wherein at the transfer position, the pallets are further movable along a horizontal linear transfer axis toward and away from the pallet transfer system. A vertical guard plate is affixed to the rotatable section or deck of the transfer system, and the plane of the guard plate passes through the rotary transfer axis at an oblique angle to the linear transfer axis. The rotatable guard plate interacts with an elastomeric seal at the interface of a guard opening in a stationary guard assembly on a machine tool to substantially confine coolant overspray and the like within the machine guard enclosure. By passing obliquely across the linear transfer axes of the pair of parallel pallets, substantially full access of a stationary pallet lying outside the machine guard enclosure may be had.

Abstract: A method and apparatus for executing a set-up cycle of operation to automatically move a cutting tool and workpiece into close proximity from an unknown positional relationship. After selecting the set-up mode of operation, the cutting tool and workpiece are moved together; and upon detecting superficial contact, the cutting tool and workpiece are separated by a selectable distance. The cycle of operation may also be used to establish the absolute position of the working edge of the cutting tool from which subsequent cutting tool motion may be measured.

Abstract: A method is disclosed for modifying coordinate data in a machining program in response to workpiece measurements made by a programmably controlled surface sensing element. The location of the workpiece and position of workpiece characteristics are determined by a series of programmed scanning cycles. The maximum, minimum and average measured positions of points on a workpiece surface are stored and may be used to calculate position offsets which may be used to modify a machining program. Further, the measured positions and offsets may be tested against programmed maximum and minimum limits to determine if the measured positions are within a tolerance band. In one embodiment, the positions of points on the workpiece surface are measured by a cutting tool operating in conjunction with a torque measuring circuit.

Abstract: A grinding machine has a base and a pair of work support bars journalled within the base. A table is journalled with the support bars in such fashion that it is axially movable along the parallel spaced bars and pivotable around one bar central axis while the other bar is radially displaced relative to the base. A pair of ramp surfaces having ramp planes disposed transversely to the pivot axis of the table are provided on the radially movable bar, such that a wedge feed is accomplished by relatively moving a powered wedging device along the ramp plane to thus radially move the movable bar, thereby causing table feed movement with respect to the base. A work support head stock is preferably carried on the base, and a wheelhead having a rotable grinding wheel is carried on the table, so that pivotal movement of the table causes relative feed movement of the grinding wheel with respect to a supported workpiece.

Abstract: A gage controlled grinding method for oppositely disposed commonly tapered end bores in a workpiece, maintaining a constant spacing of two identical bore gage diameters independent of part length is disclosed. A machine such as an internal grinding machine utilizes a drive plate and support shoes for locating and driving the workpiece, and a pair of gage fingers are provided at axial points proximal and distal to the drive plate. A first tapered bore in the outboard end of the workpiece is ground and gaged to a predetermined diameter at a first fixed gage distance from the curve plate. The workpiece is turned end-for-end on the drive plate, and the previously finished bore is sampled by a second gage finger located at a second fixed gage distance from the drive plate. The sampled diameter is compared with a predetermined stored value, and the sampled diameter is subtracted from the predetermined stored value to generate a difference value.

Abstract: An article gripping apparatus has a housing moved into proximity with a part to be gripped. A clamp finger is pivoted on the housing by an actuator biased by a first "stiff" spring reacting against the housing. In the clamped position, an interference wedge block is biased against the clamp finger by a second, "soft", spring reacting against the actuator to prevent the finger from opening under the influence of an external force. A piston portion of the actuator is contained in a cylinder portion of the wedge block. When pressurized fluid is ported to the cylinder cavity, the wedge block is first retracted from the clamp finger, overcoming the second, "soft", biasing spring. When the wedge block contacts a fixed shoulder in the housing, the actuator piston is then forced away from the shoulder, overcoming the first, "stiff", biasing spring, pivoting the finger to an "open" position.

Abstract: A method is disclosed for detecting the presence of a workpiece characteristic and controlling the sequence of execution of operational steps in a machining program. First instructions in a machining program cause a sensing element to execute a scanning cycle to detect workpiece characteristics.

The next operational step may be sequentially located in the program or may be identified by third instructions which define a nonsequential program location. Jump instructions are also provided to execute an unconditional jump to operational steps defined by a jump location instruction in the program.

Abstract: A computer control is utilized to exclusively control the cycles of operation of a machine. The computer control contains a memory for storing a part program defining a number of independent machine processes. Each machine process is defined by a series of machine functions. In accordance with the execution of a part program or the exercise of pushbuttons, the control requests the execution of a machine process. An instruction block defining the first function in the process is examined, and the actual states of selected input signals defining the current machine conditions are compared to predetermined states. If there is a difference between the actual and predetermined states of the selected input signals, an error signal is generated identifying the selected input signals which are in error. If the actual and predetermined states are the same, an output signal is transferred to the machine to actuate a device thereby executing the first function.
