Подрезка получилась точной.

Here получилась is the past tense of получиться, which often means to turn out, to come out, or to end up being.

So Подрезка получилась точной means something like:

• The cut turned out precise
• The trimming came out accurate
• The maneuver ended up being precise

This is a very common Russian way to talk about the result of an action.

Because the subject подрезка is feminine singular.

In the past tense, Russian verbs agree with the subject in gender and number:

• получился — masculine
• получилась — feminine
• получилось — neuter
• получились — plural

Since подрезка is a feminine noun, the verb must be получилась.

Because after получиться, Russian usually uses the adjective in the instrumental case when describing what something turned out to be like.

So:

• точная = nominative feminine singular
• точной = instrumental feminine singular

This pattern is very common:

• Фильм получился интересным. — The film turned out interesting.
• Статья получилась полезной. — The article turned out useful.
• Подрезка получилась точной. — The cut/maneuver turned out precise.

So точной is not random: it is the normal form required here.

It is an adjective, not an adverb.

Why?

Because it describes the noun подрезка, and it matches it in gender and number, while appearing in the instrumental case because of получилась.

Compare:

• точной — adjective form
• точно — adverb

For example:

• Подрезка получилась точной. — The cut turned out precise.
• Он подрезал точно. — He cut precisely.

So in your sentence, точной means precise as a quality of подрезка.

The dictionary form is точный.

That is the masculine nominative singular form, which is how Russian adjectives are usually listed in dictionaries.

Some forms are:

• точный — masculine nominative
• точная — feminine nominative
• точное — neuter nominative
• точные — plural nominative
• точной — feminine instrumental / feminine dative / feminine genitive / feminine prepositional, depending on context

In this sentence, точной is specifically feminine singular instrumental.

Because получилась emphasizes the result.

Compare:

• Подрезка была точной. — The cut was precise.
  This just states a quality.

• Подрезка получилась точной. — The cut turned out precise.
  This emphasizes how the action/result came out in the end.

So получиться often suggests:

• the result was achieved
• things turned out a certain way
• there is an element of outcome, not just description

This is often more natural than была when talking about something someone did and how it came out.

Подрезка is a noun. It is formed from the verb подрезать.

Very roughly:

• подрезать — to trim / cut / cut off / undercut, depending on context
• подрезка — a trimming, a cut, a cutback, a cutting-off maneuver, etc.

The suffix -к-а often forms nouns for actions or results of actions.

So grammatically in this sentence:

• Подрезка = subject, nominative singular
• получилась = past tense verb, feminine singular
• точной = predicate adjective, instrumental feminine singular

Yes. Russian word order is flexible, although the neutral order here is:

• Подрезка получилась точной.

Other orders are possible, but they shift emphasis:

• Точной получилась подрезка. — emphasizes точной
• Получилась точной подрезка. — more literary or context-dependent

For a learner, the given order is the most neutral and safest.

Because it refers to a completed result.

The speaker is looking at the outcome and saying that the cut/maneuver turned out precise.

If you wanted a present-time or ongoing sense, you could say:

• Подрезка получается точной. — The cut is turning out precise / comes out precise.

But in many real situations, especially when evaluating something already done, the past tense is the natural choice.

The main stresses are:

• подрЕзка
• получИлась
• тОчной

So the sentence is pronounced approximately:

подрЕзка получИлась тОчной

Stress is important in Russian, because it is not always predictable from spelling.
