Abstract
An information indicating that a pattern machining data for an industrial machine, which data is a collection of sectional machining data each including workpiece feed amount for each sectional machining and machining information for each sectional machining, is made contiguous to another machining data is inserted into a predetermined one of the machining data so that a plurality of machinings whose data size exceeds a capacity of a machining data memory of the machine can be can be performed thereby continuously.
Claims39
A machining data preparing apparatus for an industrial machine of the type which machines a continuous machining pattern on a workpiece, comprising:
- input means for inputting multiple groups of partial coordinate data, each group representing a partial machining pattern corresponding to a segment of said continuous machining pattern;
- memory means for storing each of said groups of partial coordinate data and a corresponding identification code as a machining pattern data set for one of said partial machining patterns, wherein a capacity of said memory means is substantially equal to a size of said machining pattern data set;
- pattern data input/output means for transferring each of said machining pattern data sets from said memory means to a storing medium and for selectively deriving at least one of said machining pattern data sets from said storing medium according to said identification codes;
- and
- operation means for assembling a plurality of said pattern data sets derived selectively from said storing medium, through said pattern data input/output means, according to connection codes, each of which instructs a connection between one of said machining pattern data sets and another machining pattern data set, to produce said continuous machining pattern from said partial machining patterns.
A data preparing device for an industrial machine including an execution memory of a predetermined maximum data size, comprising:
- means for producing machining data including a plurality of sectional machining data sets, each of said sectional machining data sets having less than said predetermined maximum data size and including a workpiece feed amount and machining information for a corresponding machining section which represents a segment of a continuous machining pattern whose continuous data set is larger than said maximum data size;
- means for separately storing each of said sectional machining data sets with a corresponding identification code in memory;
- means for selectively reading said sectional machining data sets from said memory by using said identification codes as keys;
- means for inputting said identification codes for said plurality of said sectional machining data sets;
- means for indicating a connection of said plurality of said sectional machining data sets inputted with said identification codes;
- and
- means for connecting in response to said identification codes corresponding sectional machining data sets.
A sewing data preparing apparatus for generating a complete sewing pattern for a sewing machine having an execution memory of a predetermined maximum size from sewing data including a plurality of stitch data commands, each of which includes a feed amount and sewing information for each stitch of a sewing machine, comprising:
- means for inputting groups of said stitch data patterns, representing portions of a continuous sewing pattern, wherein each of said portions is less than said predetermined maximum size and wherein all of said portions combined total more than said maximum size;
- and
- means for inputting sewing information indicative of a connection between first and second groups of stitch data commands of said sewing data.
A method of preparing sewing data for an electronic sewing machine including an execution memory of a predetermined maximum size, said sewing data being formed from a plurality of stitch data commands each including a cloth feed amount for each stitch and sewing information for each stitch, comprising the step of:
- inputting sewing data for multiple groups of stitch data commands, each group representing a portion of a continuous sewing pattern, each said portion being less than said predetermined maximum size but collectively being larger than said predetermined maximum size;
- and
- inserting, into a predetermined one of said groups of stitch data commands, information indicating that one of said groups of sewing data commands is contiguous with another one of said groups of sewing data commands.
