摘要： In a numerical control of a machine tool, the relation between the total number of instructions, or the range of movement of the movable member of the machine tool and the actual amount of movement is not represented by a straight line but periodically change sinusoidally over substantially equal ranges of movement, due to a lead error of a ball screw used for moving the movable element. For the purpose of correctly compensate the position error in a short time, the total range of movement of the movable element is divided into a plurality of ranges, and start and end points of movement, types of movement of respective ranges and periods thereof are stored in memory means. The actual position of the movable element and the data stored in the memory means are used to correct the actual position of the movable member.

摘要： A processing method and a processing machine for restraining abrupt increase in a load applied to a tool in entering a workpiece and for avoiding decrease in tool's life span are provided. When an end mill EM is entered into a processing surface of a workpiece W, the end mill EM is first entered obliquely to a processing surface of the workpiece W, and is moved oppositely to the entering direction while keeping the cutting depth. Alternatively, the end mill EM is entered obliquely to the processing surface of the workpiece W and is moved oppositely to the entering direction while gradually increasing the cutting depth of the end mill EM. When the cutting depth reaches a predetermined cutting depth, the end mill EM is moved parallel to the processing surface of the workpiece W.

摘要： A history of function values of a spindle rotation frequency in each time period from present to past is stored in a data table 22D and corrective coefficients are stored in advance in a corrective coefficient table 22C relating the coefficients to the location in the data table 22D. Each location and corrective coefficient are read out from the corrective coefficient table 22C and the function value of the spindle rotation frequency corresponding to the location is read out from the data table 22D. The compensation value is calculated from the total sum of each product of the function value and the corrective coefficient in each location and compensate the NC command position with the compensation value.

摘要： A surface finishing method and a machine therefor, in which good finish accuracy can be obtained in all carving surfaces and deterioration of tool's life can be prevented. When a surface of a concave portion formed on a workpiece is carved, an end mill is first revolved along an outermost side of a slope, and is moved toward inside and revolved along a circumferential direction. When a surface of the slope is carved, a movement path of the end mill is selected so that the surface of the slope is down-cut. When a bottom is carved, the end mill is moved from inside to outside, in other words, the movement path is selected so that a surface of the bottom is down-cut.
