Title: Method and device for control of feed speed for numerical control
Inventor: YOSHIDA JUN
IPC: G05B19/416
Filed: 1991-08-30
Abstract: PURPOSE:To enable high speed and high efficiency machining even including the circular arc processing by setting a deceleration start point based on the circular arc machining end point and the deceleration speed set previously so as to secure a prescribed deceleration speed. CONSTITUTION:A data receiving/decoding part 2 receives and decodes the machining shape data and the feed speed data which are read out of a recording medium 1 like a numerical control NC tape, etc. A circular arc block deceleration deciding part 3 decides whether the deceleration is needed for a circular arc machining block or not based on the machining shape data. If not, a command feed speed is designated to a servo part 6 and maintained there. If so, the end point of the corresponding circular arc is obtained and sent to a deceleration start point computing part 4 together with the deceleration feed speed set in a circular arc machining state. The part 4 calculates a deceleration start point from the command feed speed and the fixed acceleration. A deceleration control part 5 receives the deceleration start point information and instructs the part 6 to start the deceleration of the feed speed.

IPC: F16K1/22
Filed: 1990-09-13
Abstract: PURPOSE:To obtain a useful life almost twice as much as that of the conventional one by removably fitting a sleeve with an outer peripheral center axis passing through the center to a valve box, providing flanges corresponding to the upper and lower surfaces of a valve box on the outer peripheral surface of the released sleeve, and removably screwing a bracket mounted over both the flanges. CONSTITUTION:Center axes of valve boxes 11 and 12 are eccentric from a center axis O of the peripheries of sleeves 13A and 13B, and are respectively crossed at right angles to a passage axial line Fx at a position Os1 (in the state that a valve body-valve seat 8 can be engaged with a first valve box-valve seat 5), or a position Os2 (in the state that the valve body valve seat 8 can be engaged with a second valve box valve seat 6). Since a center axis Ob of the valve box-valve seat surface is apart from a valve box center axis Os by a distance of Ls in the direction of Fy rectangular to a Fx line, an equation of Ev=Ls is obtained. In the above equation, 180 deg. rotation of the valve body in the valve box requires a condition of the shortest distance between the center axis O of the outer periphery of the sleeve and the valve box-valve seat surface being larger the longest distance between the center axis of the outer periphery of the sleeve and the valve box-valve seat surface, and consequently, a relationship of Eb>Ev is brought about, and thus an equation of Lb=EXsin beta is added.
