The workpiece path to be added is regarded as into a standard items machining path accordingly.
Referring to Fig. 5, its flow diagram for the fourth embodiment of Work piece processing method of the invention.As shown,
The present embodiment and previous embodiment the difference is that, can also include a scanning step S20 before step S21: will be with a collection of
Remaining semi-finished product of amount carry out 3-D scanning one by one, generate a semi-finished product scanning information with corresponding.And in step S21, then may be used
To carry out three-dimensional alignment using semi-finished product scanning information and standard items, to plan the production and processing path of semi-finished product.Actually answering
In, after obtaining the semi-finished product scanning information of each semi-finished product, computer or related software, cooperative mechanical arm can use
The position of semi-finished product is adjusted, the planning in production and processing path is more accurately carried out with benefit.Certainly, the production and processing road described in this
Diameter refers to the control data of mechanical arm energy interpretation.By the scanning step S20, the production and processing cooked up will can be made
Path is more accurate, and promotes the production yield of subsequent finished goods.
As shown in fig. 6, in the 5th embodiment of Work piece processing method of the invention, after executing above-mentioned steps S20, Yu Bu
In rapid S21, then it can correspond to and carry out three-dimensional alignment using each semi-finished product scanning information and standard items, then again according to three-dimensional ratio
Comparison to gained as a result, and modified based on standard items machining path, to form institute corresponding to each semi-finished product
State production and processing path.In other words, the production and processing path of each semi-finished product can be with each semi-finished product scanning letter of direct basis
It ceases with standard items three-dimensional alignment as a result, being modified based on standard items machining path, obtains production and processing path accordingly,
Without planning generation again again, whole prouctiveness can so be substantially improved.
Specifically, in actual work piece production manufacturing process, machining path planning is carried out to three-dimensional workpiece, is needed
It takes a substantial amount of time, and the spent time is also substantially directly proportional to difficulty of processing.Therefore, the utilization that the present embodiment is proposed
Standard machining path is modified, and to form the production and processing path of semi-finished product, can will substantially shorten the production and processing of semi-finished product
The time of path planning.Furthermore by the semi-finished product that same batch is produced, the change in size of the semi-finished product of part to each other
It is relatively small, it therefore, is modified on the basis of standard items machining path, to form the production and processing path of each semi-finished product
Speed will be substantially better than the speed in the production and processing path for planning semi-finished product again.
In various embodiments, with each semi-finished product in batch, after Yu Zhihang step S21, standard items are processed
The modification that path is carried out can be recorded in database, after identical modification is performed for several times, then can add to standard items
Work path is modified, and subsequent semi-finished product is made to carry out production and processing path on the basis of modified standard items machining path
Planning, in this way, by can reduce planning semi-finished product production and processing path needed for the time.
Referring to Fig. 7, its flow diagram for the sixth embodiment of Work piece processing method of the invention.As shown,
The present embodiment and previous embodiment the difference is that, can also include a detecting step S3 after volume production making step S2:
Step S31: to multiple default locations of at least one finished goods, position corresponding with standard items is compared
It is right, to generate a mismachining tolerance information；And
Step S32: according to multiple mismachining tolerance information, selection sexually revises at least one default processing ginseng of mechanical arm
Number.
In specific implementation, in step S31,3-D scanning first can be carried out to each finished goods, then according to scanning institute
As a result, cooperative mechanical arm adjustment finished goods position, then by way of various comparisons (e.g. utilize mechanical arm
Respectively in a manner of contacting finished goods and standard items, using image capturing, utilize scanning information etc.), entirety to finished goods or
It is that multiple default locations are compared.In different applications, in Yu Suoshu step S31, each finished goods can be measured
Thickness or appearance geometric dimension, generate a thickness information or an appearance information with corresponding, accordingly with standard items
It is compared, to generate the mismachining tolerance information.
For example, therefore semi-finished product may can use ultrasonic in step S31 by the process of grinding
Detection device carries out Thickness sensitivity to finished goods, to confirm whether thickness of the finished goods after grinding reaches scheduled standard；
In the case where finished goods has circular arc appearance, then it can use related optical detection device, to each arc position of finished goods
It sets and carries out appearance detection, to confirm whether each arc surface reaches expected radian.Certainly, according to the processing of practical work piece
Operation is different, and the mismachining tolerance information, which can wrap, contains other different measurement informations.
In other examples, each finished goods mismachining tolerance information caused by step S31, can be recorded in
In database, and the mismachining tolerance information generated when finished goods is corresponding, belong to when can reprocess range, then the finished goods can
To be classified as reprocess workpiece.Relatively, the mismachining tolerance information corresponding to the finished goods, it is non-belong to can reprocess range,
And when having exceeded allowable range, then it can be classified as defective products.In step s 32, the default machined parameters can wrap
It, can be according to needing containing the posture etc. when cutting point, process tool type, moving direction, amount of movement, rotation angle, tool sharpening
It asks and is changed, it is without restriction in this；In practical applications, aforementioned planning one workpiece machining path to be added, standard items processing
Path or production and processing path, can wrap and preset machined parameters containing these.
In practical applications, when mechanical arm processes semi-finished product, may because of various unexpected problems,
And there is a situation where target processing result and actual processing results error.Therefore, it by above-mentioned detecting step S3, can collect
The mismachining tolerance information of each finished goods, and the relevant default of processing operation of the mechanical arm to semi-finished product is suitably adjusted accordingly
Machined parameters carry out processing operation to semi-finished product so as to make mechanical arm more accurately according to scheduled production and processing path.
Certainly, detecting step S3 can be the volume production making step S2 after the completion of or volume production making step S2 completes predetermined quantity
It is executed after finished goods, it is without restriction in this.
Referring to Fig. 8, it is the flow diagram of the seventh embodiment of the present invention.As shown, the present embodiment with it is aforementioned
First embodiment it is maximum the difference is that: in step S11, three first can be carried out at least one or each semi-finished product
Dimension scanning generates a semi-finished product scanning information with corresponding, then according to multiple semi-finished product scanning informations, selects workpiece to be added.
Specifically, semi-finished product scanning information corresponding to workpiece to be added can be closest to all semi-finished product scanning letter
The average value of breath；In other words, it by the semi-finished product scanning information, can choose out in batch, with remaining semi-finished product
The smallest semi-finished product of size difference are as workpiece to be added.In this way, the speed that volume production making step S2 execution will can be substantially improved, and
The difference of finished goods produced by same batch to each other can be effectively reduced.
It illustrates, in existing technology, part manufacturer is for used in workpiece (especially metal works)
Robotic arm religion point path processing method or the planning that machining path is directly carried out with CAD design archives, all there are parts
Disadvantage.Specifically, the robotic arm religion point path processing method, user must first pass through relevant introduction equipment, instruct
Which kind of processing mechanical arm carries out to workpiece in which position in space, using what is processed as mechanical arm to subsequent workpiece
Machining path；Such method, when in production process change in size occurs for semi-finished product, mechanical arm follows original design
Fixation machining path, semi-finished product is processed, will be easy to produce the defective products for not meeting allowable error.
